POLYBAC #307WB-LARGE - POLYGEM, Inc.

3. PRODUCT DESCRIPTION
POLYBAC #307WB-LARGE is a large bead and silicon carbide filled, non-sag, epoxy wearing compound designed for ambient temperature applications. POLYBAC #307WB-LARGE exhibits excellent adhesion to metals, fiberglass, concrete, wood and ceramic tiles. This 100% solids, water clean-up, abrasion resistant compound is recommended for repairing and reshaping pipe elbows, chutes, feeders, pump casings, cyclones, fans, housings, crushers, slurry pumps and other equipment exposed to sliding, wear abrasion and impact.

POLYBAC #307WB-LARGE can be used to fill in irregular shaped surfaces and to repair loose or broken ceramic tile. This wearing compound can be featheredged to contoured surfaces such as chippers, screening decks and separators.

POLYBAC #307WB-LARGE can be used in temperature environments of 200°F constant and 250°F intermittently. This product also exhibits good chemical resistance and good thermal shock properties.

4. APPLICATION INSTRUCTIONS

Prepare surface to be bonded by sandblasting or scarifying to eliminate all surface scale, rust and uncleaned matter that may affect the adhesion of the compound. A coarse wheel or disc can be used to remove rough, uneven areas of previously applied adhesive or tile. Wipe surface with clean cloth soaked with POLYBAC #20 Solvent
Empty contents of Part A (resin) into 2 gallon pail containing Part B (hardener). Use power drill mixer to blend the components until uniform in color. Scrape sides and bottom of pail to insure proper ratio. Do not exceed mixing over 3 minutes. For lesser quantities: Mix 1 Part (A) and 1 Part (B) on separate board with trowel until uniform in color.
Maintain components between 50° F and 90°F. Apply a thin layer of mixed POLYBAC #307 WB-Large and rub into surface. Proceed to build up with layers of ¼” - ½” to desired thickness.
The cure can be accelerated by waving a torch over the surface for about 30 minutes or heat Part A (resin) to 100°F before mixing. This procedure will shorten the pot life of the material due to the temperature sensitivity of epoxy resins.
A smooth, slick surface can be accomplished by dipping your trowel in water then smoothing over already applied, uncured POLYBAC #307 WB-Large. Clean tools, clothes or skin with warm soapy water.
Do not apply material below 50°F unless surface and material is maintained above 80°F to insure proper adhesion.
