Durcon Epoxy Resin Countertops are filled epoxy resin, molded into homogenous, non-porous sheets with no surface coating. All sheets are color and pattern consistent throughout the thickness and will have adhesively seamed components up to a maximum practical length. Epoxy resin laptops are molded from modified epoxy resins and inert fillers that have been compounded and completely cured in processing to provide optimum physical and chemical resistance properties required of a heavy duty laboratory work surface.
Dimensions | Thickness (in) | Metric (mm) | Thickness Tolerance | Lbs/ft2 |
---|---|---|---|---|
62" x 98" | 1" | 25mm | +/- 0.050" | 10.24 |
62" x 98" | 0.75" | 19mm | +/- 0.037" | 7.9 |
In addition to the sheet size available, Durcon monolithic, solid cast epoxy lab top work surfaces, with their smooth, non-glare matte finish, are molded in several thicknesses', with the typical and industry standard thickness being 1" (25mm).
When fabricating epoxy resin laboratory tops and sheet material at the ISO 9001 certified manufacturing facility, all fabricated cuts are made with diamond tipped, water cooled, rotary saws. Sink cutouts, faucet or gas tap fixture holes or other service hole requirements, are cut with CNC diamond tipped routers and drill bits. Typical specification for epoxy countertops in accordance with The Woodworking Institute (W.I.) and its US or Canadian affiliates is 25mm or 1" Thickness. The maximum span for unsupported epoxy shall not exceed 30" (762mm) without intermediate support. The maximum cantilever shall not exceed 12" (305mm) without intermediate support.
The fabricated sheet material comes with a drip groove cut on the front underside of the sheet material at a prescribed depth of 1/8" (3mm), 1/8" (3mm) width and 1/2" (12mm) distance from the front or side edge.
EPOXY backsplash or curbing at 4" (100 mm) height is typical, also known as applied splash, is provided loose, cut to size for field application, with each sheet order, if required, to match the countertop sizing, or can be field cut from sheet material to meet job requirements. The top front edge and exposed sides are typically eased with a 1/8" bevel or chamfer.
Window Sills (Stools) Epoxy - Material shall be monolithic, cast epoxy resin product and shall consist of a polymerized cast resin material formulated to provide a surface with high chemical resistance characteristics. The combination of epoxy resin and asbestos free inert filler materials shall be oven-cured in molds to obtain maximum chemical resistance, and then removed from the molds and oven tempered to achieve maximum physical strength and stability. Surfaces shall have a uniform low-sheen matte surface finish and the materials shall be extremely hard and resistant to scratches and abrasion. Surface is to be flat with square side edges or fabricated and finished if sills protrude past wall depth. Color shall be as required by architect or site conditions, obtained from the manufacturer's standard color range. Colored Epoxy adhesive for securing interior stools to substrate shall be Epoxy Smooth-On-2 part adhesive cement.

Durcon epoxy is nonporous which makes it naturally anti-microbial, anti-bacterial, and anti-fungal growth resistant..Note: ASTM G22-76(1996) Standard Practice for Determining Resistance of Plastics to Bacteria was (Withdrawn in 2002).
Durcon epoxy resin laboratory tops are the materials of choice for the harsh environment of research laboratories R&D), K-12 schools, university, charter schools, hospitals, wastewater treatment plants or other wet lab facilities. Epoxy tops or work surface products and the Durcon epoxy sinks however are subject to thermal shock when in contact with dry ice or liquid nitrogen and our products are not warranted against damage from their use. The improper use of dry ice or liquid nitrogen may cause cracking or sink failure.
USING ASTM D-635 TEST PROCEDURE, A 3/8" (9.525mm) BUNSEN BURNER, ADJUSTED TO A QUIET FLAME WITH A 1.5" (38MM) INNER CONE, WAS OVERTURNED ON THE EPOXY WORK SURFACE FOR A PERIOD OF FIVE (5) MINUTES WITH NO ADVERSE EFFECT, WITHOUT EXHIBITING ANY BLISTERS, CRACKS, NOR ANY BREAKDOWN OF THE WORK SURFACE. DURATOP EPOXY RESIN IS SELF EXTINGUISHING AND SHOWS NO BURN RATE, IN ACCORDANCE WITH ASTM METHOD D-635.
DURATOP EPOXY RESIN WAS TESTED UNDER THE HOT CRUCIBLE TEST PROCEDURE BY PLACING A HIGH FORM PORCELAIN CRUCIBLE (15ML CAPACITY) ONTO THE LAB COUNTERTOP AFTER HEATING OVER A BUNSEN BURNER UNTIL THE CRUCIBLE BOTTOM ATTAINS A DULL RED HEAT. IMMEDIATELY AFTER, THE HOT CRUCIBLE IS TRANSFERRED TO THE WORK SURFACE AND ALLOWED TO COOL TO ROOM TEMPERATURE. THE RESULT WAS THAT THE EPOXY RESIN SURFACE EXHIBITED NO BLISTERS, CRACKS NOR ANY BREAKDOWN OF THE WORK SURFACE.
