PQLYBAC #1325 - POLYGEM, Inc.

3. PRODUCT DESCRIPTION
Polybac #1325 is a 100% solids epoxy, brushable ceramic wear compound designed for high wear resistance at a reasonable cost, it is the top choice of maintenance personnel for repair and initially protecting the wear points in pump. housing, impellers, chutes, tanks, screens, elbows, dust collectors, fans, ash pump impeller and silos.

Polybac #1325 forms a unique molecular bond with a properly prepared surface to provide a wear resistant coating. This brushable compound bonds well to cast iron, steel, non-ferrous substrates, ceramics and carbide wear materials, as well as, concrete and wood,

4. APPLICATION INSTRUCTIONS

Sandblast or scarify surface to eliminate all surface scale, rust and unclean matter. Wipe with a clean cloth, soaked with #20 Solvent. If possible, warm the substrate to 120°F.
If sandblasting is not available, wire brush, disc grinding 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 4 parts resin to 1 part hardener on a separate board until uniform in color.
Apply a thin layer of Polybac #1325, rub into the surface, then proceed to build up to desired thickness. Layers should not exceed ¼” at one time to insure proper cure.
The cure can be accelerated by waving a torch over the surface for about 30 minutes or heat Part A (resin) to 100F before mixing. This process will accelerate the cure but also shorten the working life.
A smooth slick surface can be accomplished by dipping your trowel into #20 Solvent then smoothing over the already applied Polybac #1325.
Do not apply below 50°F without heating the material and substrate to temperatures above 80F. Clean tools with #20 Solvent and clean skin or clothes with soapy water.
