A compreg is a wood laminate made by impregnating veneers with synthetic resin (usually phenolic) and curing under high heat and pressure to greatly increase density and chemical resistance.

What are the typical applications for Part 2 laminates?

They are specifically used for manufacturing chemical vats, filter press frames, and specialized industrial flooring where chemical exposure is prevalent.

How is chemical resistance evaluated under this IS code?

Test specimens are immersed in specified chemical reagents for a set duration, after which they are evaluated for changes in weight, thickness, and visible degradation.

Quick Reference Values

Specific gravity, Min1.20

Moisture content, Max6%

Water absorption (24 hours), Max2.0%

Practical Notes

Ensure all machined cut edges and joints are sealed with an appropriate chemical-resistant resin to prevent moisture ingress and delamination.

Always match the specific chemical resistance test results (acid, alkali, or solvent) with the intended operational environment of the plant or vat.
