POLYBAC® #315 AR - POLYGEM, Inc.

3. PRODUCT DESCRIPTION
POLYBAC® #315 AR High Performance Corrosion and Abrasion Resistant Lining is a two component, 100% solids, room temperature cured coating with very fine sized ceramic beads. The high performance coating has excellent acid and abrasion resistance while exhibiting good adhesion properties to various substrates.

Common applications include pump housings, tanks, troughs, scrubbers and any application where corrosion and abrasion problems exist. POLYBAC #315 AR, can be applied by brush or roller to a 30 mil thickness.

4. APPLICATION INSTRUCTIONS

Sandblast or scarify surface to eliminate all surface scale, rust and unclean matter. Wipe surface with a clean cloth soaked with POLYBAC #20 Solvent. if possible, warm the substrate to 120° F.
If sandblasting is not available, wire brush, disc grinder or a coarse sandpaper may be used. Clean with a soil free cloth, soaked with #20 Solvent.
The substrate must be free from all contamination such as oil, grease, rust, mill scale, water, release agents or soil. Mix 1 part A (Resin) to 1 part B (Hardener) on a separate board until uniform in color.
Apply a thin layer of POLYBAC #315 AR and rub into the surface, then proceed to build up to desired thickness. Layers should not exceed 30 mils at one time to insure proper cure.
The cure can be accelerated by waving a torch over the surface for about thirty minutes or heat Part A (Resin) to 100° F before mixing. This process will accelerate the cure but also shorten the working life. Material is sensitive to varying temperatures.
Do not apply below 50° F without heating the material and substrate to temperatures above 80° F. Clean tools with #20 Solvent and clean skin or clothes with soapy water. Do not apply to wet or damp substrates. May affect adhesion of coating.
