Chemical Resistance

The following tests have been performed to gauge our epoxy resin countertops’ exact levels of chemical resistance.

Method A

For the organic solvents listed below. A cotton ball, saturated with the test chemical, was placed in a one ounce bottle (10mm x 75mm test tube or similar container). The container was inverted on the test material surface for a period of 24 hours. Temperature of test: 23° +/-2° C (73° +/-4° F).

Method B

For all chemicals listed below other than the organic solvents. Five drops (1/4cc) of the test chemical were placed on the test material surface. The chemical was covered with a watch glass (25mm) for a period of 24 hours. Temperature of test: 23° +/-2° C (73° +/-4° F).

Evaulation

After 24 hour exposure, exposed areas were washed with water, then a detergent solution and finally with isopropyl alcohol. Materials were then rinsed with distilled water and dried with a cloth. Samples are numerically rated as follows:

  1. No Effect - No detectable change in the material surface
  2. Excellent - Slight detectable change in color or gloss but no change in function or life of the surface
  3. Good - A clearly discernible change in color or gloss but no significant impairment of surface life or function
  4. Fair - Objectionable change in appearance due to dis- coloration or etch, possibly resulting in deterioration of function over an extended period of time
  5. Failure - Pitting, cratering, or erosion of the surface. Obvious and significant deterioration

Physical Characteristics

  • Thickness - Epoxy resin is a solid product, it is not a laminate
  • Water Absorption - Epoxy resin does not absorb moisture
  • Fire Resistance - Epoxy resin is flame-resistant
  • Heat Resistance - Epoxy resin can withstand a great deal of heat before deflecting. For comparison, solid-surface material deflects at 90° C under the same test conditions
