POLYBAC #313 - POLYGEM, Inc.

3. PRODUCT DESCRIPTION
POLYBAC #313 is a trowelable wear resistant, ceramic bead filled, polymer coating for high wear resistance at a reasonable cost. It is a top choice of maintenance personnel for repair and initial protection for wear points in pump housings, impellers, chutes, tanks, screens, elbows, dust collectors, fans, and silos, as well as many other applications.

POLYBAC #313 forms a unique molecular bond with a properly prepared surface. Types of materials it bonds well with include: 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 surface with a clean cloth soaked with PQLYBAC #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 #313 WEAR RESISTANT POLYMER COATING and rub onto 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 thirty minutes or heat Part A (Resin) to 100°F 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 #313.
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.
