Corian
The seamless monolith of your ideas
6 IMAGES — CLICK TO EXPAND
Corian is a solid-surface acrylic composite developed by DuPont in 1967 and now produced under the Corian Design brand (a DuPont de Nemours division). It consists of approximately one-third acrylic resin and two-thirds aluminum trihydrate (ATH), resulting in a nonporous, hygienic material capable of thermoforming. Its defining advantage is invisible seam bonding: two sheets joined with same-chemistry adhesive create a monolithic surface of any length — an effect impossible with quartz agglomerate or natural stone. Corian is certified under ASTM D6580 (cast acrylic sheets) and has passed NSF/ANSI 51 testing for direct food contact.
TECHNICAL PASSPORT
Three Corian Design product lines cover the full spectrum of design applications: Corian Solid Surface (classic, 170+ colors), Corian Quartz (quartz agglomerate, 93% quartz), and Corian Endura (facades). Sheet thicknesses: 6, 12, and 12.3 mm — laminated up to 50 mm when needed. Thermoforming at 160°C allows bending into 3D shapes: radiused edges, integrated sinks, wave-form reception desks. We have completed over 80 Corian projects in 10 years — from the Federation Tower lobby desk (Moscow City) to bar counters at Nobu restaurants. According to Corian Design Global, the material is installed in 1,400+ European hospitals due to its antibacterial properties and seamless sink integration. Key advantage: Corian is repairable — scratches and burns are sanded out with P320–P400 grit paper in 10 minutes, unlike quartz agglomerate where a chip means panel replacement.
Varieties & Types
Glacier White
$$$DuPont, manufactured in China / Germany
Pure white without inclusions — the best-selling Corian color worldwide. A standard for medical facilities, laboratories, and minimalist kitchens. When backlit from below, produces a soft glow due to slight translucency.
Deep Nocturne
$$$DuPont, Corian Solid line
Absolute matte black. In practice, demanding — micro-scratches and water spots show on the dark surface. Best used in low-traffic zones: windowsills, decorative panels, reception accent elements.
Sahara (Savannah)
$$DuPont, Corian Solid line
Warm sandy beige with fine granular pattern. Ideal for hospitality zones: hotel lobbies, spa reception desks, coffee stations. Effectively masks everyday stains and fingerprints.
Rain Cloud
$$$DuPont, DeepColor line
Gray with subtle veining — a concrete-look effect. Popular for loft and industrial interiors. Unlike actual microcement, it won't crack or require periodic resealing.
Ethereal (Private Collection)
$$$$$DuPont, Corian Private line
Translucent premium decor with a through-light effect. 6 mm thickness for backlighting. Used in bar tops, decorative walls, and pendant luminaires. Priced at 2.5× standard colors.
Advantages
- ✓Seamless joining — surfaces of any length without visible joints
- ✓Exceptional repairability — scratches and burns removed with sandpaper
- ✓Thermoforming — 3D shapes, radiused edges, and integrated sinks possible
- ✓Hygienic — nonporous, certified for medical and food-service environments (NSF/ANSI 51)
- ✓Lightweight — 1.5× lighter than natural stone, reduced structural requirements
- ✓Over 170 colors — from pure white to translucent Private Collection

Limitations
- ⚠Softer than natural stone — scratched by knives and abrasive objects
- ⚠Lower heat resistance — a hot skillet leaves a mark (vs. granite at 300°C)
- ⚠Acid-sensitive — lemon juice and vinegar dull the polish (repairable but requires attention)
- ⚠Not suitable for outdoor use — acrylic resin degrades under prolonged direct UV exposure
- ⚠Limited stone imitation — cannot reproduce the depth of marble or onyx veining
- ⚠Cost comparable to natural stone at 12 mm thickness + substrate
Applications
Kitchen countertops with integrated sinks — Corian's signature application. Seamless sink + drainboard + countertop = a single monolith with no crevices for dirt. Recommended build-up: 12 mm Corian + 18 mm moisture-resistant plywood substrate. Trivets required for hot cookware.
Reception desks — approximately 70% of our Corian projects. Monolithic fronts without a single seam, radiused edges, built-in LED underlighting. For premium projects — Corian Private with a glow-through effect.
Bar counters — a popular choice for restaurants and cafés. Seamless surfaces of 20 m² and beyond. Resists staining from wine and coffee. Downside: abrasive dishware causes scratches — periodic sanding required (every 6 months).
Medical countertops and modules — Corian is certified for clinics, hospitals, and laboratories. Nonporous surface does not harbor bacteria. Seamless integrated sinks — critical for sterile environments.
Wall panels and column cladding — 6 mm Corian sheets mounted on a subframe create a seamless interior. Thermoforming allows wrapping columns without joints.
Luminaires and light panels — translucent Private Collection colors transmit light for a soft, diffused glow. Used in ceiling panels, pendant fixtures, and backlit reception desks.
Pricing & Economics
Pricing Factors
- ·Collection — Private Collection costs 2–3× more than Solid Surface
- ·Thickness — 12 mm is standard; 6 mm cladding sheets cost ~40% less
- ·Form complexity — thermoforming adds 15–30% to the price
- ·Integrated sink — molded one-piece sink adds $700–$1,500
- ·Number of seams — longer pieces need more joints (+$180/seam)
- ·Edge profile — decorative routed edges cost 20–35% more than square
Care & Longevity
Daily Care
A damp cloth or sponge with mild soap is sufficient for everyday cleaning. Corian is nonporous: coffee, wine, and tea won't stain if wiped within a few hours. On dark colors, dry-wipe to avoid water-spot marks — this is an aesthetic, not hygiene, issue.
What to Avoid
Do not place hot cookware directly on the surface — use trivets (limit 180°C; a hot skillet reaches 200–250°C). Avoid abrasive powders on gloss finishes. Acetone and solvents are acceptable briefly for adhesive removal but should not sit on the surface.
Periodic Maintenance
Renew matte finishes every 6–12 months: sand with P320, then P400 in circular motions. Gloss finishes: buff with polishing compound (e.g., 3M Perfect-It) or call a professional. The process takes 30–60 minutes for a 2 m² countertop.
Professional Care
Professional restoration (deep scratches, chips, thermal marks): from $30/sq ft. The technician removes the top 0.3–0.5 mm, fills with Corian Joint Adhesive, and polishes. Result: surface as new.
Expert Reviews
Average Rating · 5 expert reviews
«Corian delivers what stone cannot — an 8-meter seamless surface at the Federation Tower lobby desk. The bond is invisible even up close. After 4 years on matte Glacier White, there's no sign of wear. The only caveat — we had to boost the backlighting: Private Collection translucency was slightly lower than the catalog suggested.»
«Glacier White Corian countertops throughout the clinic — hygiene is impeccable, patients notice the cleanliness. A nurse once placed an autoclave unit (120°C) on the surface — no mark. But a 200°C sterilizer would have left one. In 6 years we replaced one section — a heavy instrument was dropped, chipping deep. Repair cost: $95.»
«Working with Corian is easier than stone — cuts on a standard CNC router, bonds quickly. But thermoforming is a headache: heat to 165°C and you've got 40 seconds to bend before it cracks. Ruined 3 sheets before getting the hang of it. Good material, but it demands skill. And dark colors are a fabricator's curse — every speck of dust shows.»
«A sink molded right into the countertop with no seam — that's why I chose Corian. Three years in, I clean it with a regular sponge. Removed a knife scratch with sandpaper in 5 minutes following the installer's instructions. My neighbor with a quartz countertop is jealous.»
«For hotel projects Corian is the workhorse: bathrooms, minibars, counters. At the W Hotel we used Sahara — warm tone, doesn't show fingerprints. But for a luxury lobby I choose natural stone: Corian lacks the depth of veining and the gravitas that marble or onyx deliver. Corian is about function; stone is about emotion.»
Frequently Asked Questions
It depends on your priorities. Corian wins on repairability and seamlessness: a scratch is removed in 5 minutes with sandpaper, and the sink integrates without gaps. Quartz (Caesarstone, Silestone) is harder — 7 Mohs vs. ~2.5 — and tolerates heat better (up to 300°C vs. 180°C). For a high-use kitchen with heavy cooking, quartz is more practical. For a designer kitchen with 3D shapes and an integrated sink basin, Corian is the choice.
Installed countertop pricing: from $240/sq ft for standard colors (Glacier White, Sahara) to $1,080/sq ft for Private Collection with backlighting. A typical 20–30 sq ft kitchen countertop with an integrated sink runs $4,800–$16,000 including fabrication, delivery, and installation. Prices as of Q1 2026 from authorized DuPont distributors.
Yes — and this is the material's key advantage. Minor scratches on matte surfaces: P320 grit sandpaper, then P400, in circular motions, dry. Deep cuts: fill with Corian Joint Adhesive (available from dealers, ~$35/tube), then sand smooth. Gloss finishes are trickier — use a 3M polishing compound and a felt pad. The entire process takes 10–20 minutes.
Corian is certified under NSF/ANSI 51 for direct contact with food. Its nonporous surface does not harbor bacteria — independent testing showed that Staphylococcus aureus and E. coli colonies are eliminated after standard cleaning. The material does not off-gas toxic compounds and holds Greenguard Gold certification for VOC emissions. It is installed in 1,400+ European hospitals.
Three lines: Corian Solid Surface — the classic, 170+ colors, 12 mm flat sheets, the workhorse of most projects. Corian Quartz — quartz agglomerate (93% quartz + 7% polymer), 40+ patterns mimicking natural stone. Corian Private Collection — exclusive translucent, metallic, and textured decors for art installations and designer statements.
Dark decors (Deep Nocturne, Deep Night Sky) are the most demanding: micro-scratches, water spots, and fingerprints all show. Daily: wipe with a damp microfiber cloth, then immediately dry. Monthly: sand with P400 in one direction to refresh the matte texture. Professional tip: specify matte rather than gloss for dark colors — scratches are far less visible.
An excellent choice. Water absorption at 0.02% means moisture doesn't penetrate and mold doesn't develop. Integrated basins with no gaps mean no crevices where grime collects. Warm to the touch (unlike stone at 15°C in a bathroom). Limitation: do not use Corian for bathroom flooring — it is slippery when wet.
Standard construction: 12 mm Corian sheet + 18 mm moisture-resistant MDF or plywood substrate. Total thickness — 30 mm, visually indistinguishable from a solid stone slab. For wall cladding — 6 mm with no substrate. For windowsills and shelves — 12 mm standalone. At the edge, a double-thickness buildup (24 mm Corian) creates a visual mass effect.
