Polyply ChemBlok

Corrosion Resistance

Splash and Spill (S&S)
2 ml of each reagent below were applied to a sample of the CR-900 material.
The material was cleaned and evaluated. The results are annotated below.

Fumes and Gases (F&G)
A 2"x2" sample of CR-900 was placed over a beaker of 25 ml of each reagent.
After 24 hours of exposure the panels were cleaned and evaluated. The results
are below.

Evaluation Ratings:	*None*	No detectable change in color or surface
	Excellent	Slight color/gloss change, but no effect on material surface
	Good	Clearly observable color/gloss change, no effect on surface
	Fair	Discolored with possible deterioration of material function

Unless otherwise indicated, all properties published are based on tests performed
on standard ASTM test samples and according to ASTM test methods. Values shown
are for test samples made from production materials and are believed to be typical.
No warranty is expressed or implied.
