Adhesion

Ceramic Cover CC Systems 100 has been tested for adhesion by tests corresponding to ASTM D-3359, a cross hatch adhesion test, resulting in a score of 100% (the highest on a scale of 1 to 100). Furthermore, Dunkin & Bush, Inc. an industrial paint contractor in Seattle, WA, performed an Elcometer Adhesion Test. Coating was spray applied using air assisted airless equipment.

The coating thickness ranges from 75 mils DFT to 45 mils DFT across the tested coupon on tightly adhered mil scale. The initial test was performed 20 days after application. The result was a pull strength of 210 psi at 74 mils DFT. The coating was disbonded leaving 3-6 mils on the substrate. The final pull test was performed about 30 days after final cure.

"...Ceramic Cover CC Systems 100 reaches full adhesive strength prior to final cure."

The result was a pull strength of 210 psi at 45 mils DFT. The coating again disbonded leaving 3-4 mils on the substrate. Ceramic Cover CC Systems 100 has been tested under ASTM D4541 Test Method for pull of strength of Coating using portable adhesion testers. The conclusions are that Ceramic Cover CC Systems 100 reaches full adhesive strength prior to final cure. Further conclusion based on disbondment within the coating shows an actual stronger bond to the substrate surface.
