Description
This epoxy-based, fiber-filled material is designed for vertical surface applications.
Plasti-Paste™ EPOXY consists of two components: Part A (paste) and Part B (liquid), with a mix ratio of 2A:1B by volume or weight.
The Working time is 40 minutes, and it cures in 16 hours at room temperature, with heat application reducing cure time.
The mixed material holds vertical surfaces without sagging and cures to a rigid, strong finish.
Plasti-Paste™ EPOXY can be colored with UVO™ colorants and sanded, machined, and painted with acrylic enamel paints.
It is suitable for use as a support shell or mother mold material to reinforce rubber molds during casting, as well as for creating themed environments, art, or special effects.
Plasti-Paste™ EPOXY also serves as a powerful adhesive and repair material for industrial applications.
Features
- Not affected by moisture

Instructions
Store and use materials at room temperature (23°C). Use in a well-ventilated area, wearing a NIOSH approved respirator, safety glasses, long sleeves, and rubber gloves. Test a small application to ensure suitability.
Applying A Release Agent
Use a sealer followed by a release agent to facilitate demolding. Apply Sonite™ Wax and Ease Release™ 200 release agent. Aluminum foil can also be used as a barrier.
PRE-MIX Part A Before You Start
Pre-mix Part A to re-disperse oil and paste components.
Measuring
Use two containers: one for measuring Part A and Part B, and a larger one for mixing.
Mixing
Mix ratio is 2A:1B by weight or volume. Fill the measuring container with Part A, eliminate air voids, and transfer to the mixing container. Repeat for Part B. Mix thoroughly for 2-3 minutes, scraping sides and bottom. Add colorants to Part A before mixing with Part B.
Mixing Large Batches
Use a ‘Turbine’ mechanical mixer for large batches. Extend pot life by spreading mixed material in a flat container.
Applying
Apply uniformly with a spatula. Apply at least 0.64 cm (1/4”) thickness, 1 cm (3/8”) for maximum strength. Embed supports for stability. Smooth the final layer with solvent.
Making A Two Piece Shell
Use a barrier coat of paste wax and Ease Release™ 200 Mold Release to prevent adhesion. Aluminum foil can also be used.
Curing
Handling strength develops in about 16 hours. Full strength in 24 hours.
Heat Resistance
Fully cured material with a minimum thickness of 1 cm (3/8”) resists temperatures up to 76°C.
Painting
Ensure the surface is clean before painting with acrylic enamel paints.
Storage
Store assembled molds on a level surface indoors at room temperature in a dry place.
