Prime Epoxy Resin Is...

  • Non-toxic
  • Resistant to most organic and inorganic chemicals
  • Resistant to mechanical and thermal shock
  • Economical, due to special formulation procedures which keep costs at the level of most conventional laboratory tops
  • Not dependent on surface coatings for durability and resistance

Modified epoxy resins with inert fillers are cured for several hours to produce excellent physical, chemical, and heat resistance.

Why Prime Epoxy Resin?

Epoxy's natural resistance to corrosion has made it the material of choice for laboratory work. PRIME has gone that extra step to not only provide the excellent material, but also the added responsibility of complete fabrication. PRIME will accomodate your every epoxy resin countertop need, from initial budgeting, through estimating and bidding, to molding and fabricating to your shop drawings and details.

Prime Epoxy Resin Specifications

Tops and curbs shall be molded from a modified epoxy resin that has been specially compounded and cured to provide optimium physical and chemical resistance required for a heavy duty laboratory working surface. Impregnated stone and/or furane resins are not equal. Tops and curbs shall be a uniform mixture throughout, and shall not depend on a surface coating that can be readily removed by chemical or physical abuse.

Tops and curbs shall be non-glaring matte finish and black in color.

Tops shall be a thickness as required with a drip grove provided on underside of all sink top exposed edges. All edges shall have slight radius.

Curbs shall be bonded to the surface on the top to form a square water-tight joint. All joints in tops to be bonded with an approved epoxy cement and shall be smooth and water-tight.

Counters with integral curbs shall have a junction with a 3/4" radius, except around columns and special cutouts, which will have a standard bonded curb.

Prime Epoxy Resin Chemical Resistance

Epoxy-resin is highly resistant to the normally used laboratory alkalies, alcohol, acids, and solvents. The following solutions listed were tested for a period of 24 hours with optimal resistance.


Acetic Acid Glacial Chloroform Methyl Alcohol
Acetone Chromic Acid Nitric Acid
Ammonium Hydroxide Ethyl Alcohol Phenol
Amyl Acetate Ethyl Ether Phosphoric Acid
Aqua Regia Formaldehyde Silver Nitrate
Benzene Hydrocloric Acid Sodium Hydroxide
Butyl Alcohol Hydrofloric Acid Sulphuric Acid
Calcium Hypochlorite Hydrogen Peroxide Xylene
Carbon Disulfide Kerosene Zinc Chloride

Prime Epoxy Resin Fire Resistance

A Bunsen burner overturned on working surface for several minutes causes no adverse effects. Epoxy resin is self-extinguishing, in accordance with ASTM-Method D-635.
