Durasein Solid Surface: Chemical Resistance

Durasein is not just about creating surfaces; it’s about engineering solutions that stand the test of time and use.

In our quest to provide you with materials that elevate your creative projects, we’ve put our surfaces through a series of comprehensive tests.

The findings? A remarkable resistance to stains and damages caused by various chemicals, from household cleaners to tougher industrial agents.


This document includes stain and chemical resistance testing results of Durasein brand solid surface in accordance with CSA B45.5-17/IAPMO Z124-2017. Six (6) 15″ by 15″ panels of solid surface material were submitted. The panels were prepared in accordance with section 5.11.1(b) by wet rubbing, two drops of each reagent were placed on the surface. One drop was covered with a watch glass while the other was left exposed to ambient laboratory conditions for 16 hours. At the end of the exposure, samples were rst cleaned and then evaluated for defects and were rated 1 – 5.

Class 1

Removeable by washing with water and a cheesecloth for 20 cycles.

Class 2

Removeable by washing with naphtha and a cheesecloth for 20 cycles.

Class 3

Removeable with 20 cycles of wet rubbing with abrasive powder.

Class 4

Removeable with 40 additional cycles of wet rubbing with abrasive powder.

Class 5

Removeable by renewing the surfacing.

Although our surfaces are resiliant to most staining you should always remove chemicals quickly to avoid damage to surfaces.

**If stains persist after cleaning, remember you can renew all of our surfaces with light sanding followed by professional fabrication finishing techniques.

Some of the more aggressive reagents caused notable surface swelling in addition to the rated stain and surface texture changes. In accordance with section 5.11.3 the thickness of material removed to eliminate a stain must not exceed 0.005 in.

*The only reagents failing that criteria were Nitric Acid 70%, Nitric Acid 30%, and Nitric Acid 25%. All the other reagents passed the stain requirements of the standard. Furthermore, all reagents met the criteria of 5.4.2 and no cracks, chipped areas or blisters were observed. The docuemented swelling was not a fault described in the standard. As it was removable using the 400-grit sandpaper, it was considered to be equivalent to a texture change for the purposes of evaluation.

Covered & uncovered reagents that required sanding (0.005″ or less) after testing to remove stain and swelling.
