High Temperature High Strength Polyester Paste

High Temperature High Strength Gel

Epoxy.com PolyPaste


Epoxy.com POLYPASTE is a fast-setting industrial filler paste used for manufacturing, fabrication and repair in aircraft, aerospace and other industries having requirements for above normal temperature exposure. Fast and permanent applications are achieved by POLYPASTE. The service temperature of Filler 7 is up to 400°F (205° C). POLYPASTE is used in the construction industry to seal cracks for injection and for patches used on concrete, wood, steel and other suitable construction materials.

Excellent machining and finishing results are accomplished by grinding, sanding, scraping, etc. When exposed to elevated temperatures,POLYPASTE has a tendency to darken but does not gas, bubble, or cause any finish distortion. This product does not contain wax and readily bonds to itself and other substrates such as FRP/SMC, hi-temp epoxy molds, aluminum, steel, cast iron, urethane foam parts, etc. POLYPASTE is non-metallic, non-conductive, and non-sparking.


Surface Preparation

Priorto application, area to be repaired should be roughened and thoroughly wiped clean to ensure proper adhesion.

Mixing Instructions

Thoroughly blend 100 parts resin (a golf ball sized mass) with 2 parts (2? strip) hardener for 1 1/2 minutes in a clean dry container carefully scraping sides and bottom of container during the mixing process to ensure uniformity.


Epoxy.com POLYPASTE should be applied by buttering onto area to be repaired. After material has cured, the repair area can be sanded to desired surface finish.


POLYPASTE should be stored at a temperature less than 75° F. Storage above 75° F will shorten the shelf life and render the product unusable. The shelf life for this product is six months.
