Instructions
Use in a well-ventilated area and wear protective gear. Avoid using glass or foam containers due to high exotherm. Store and use at room temperature (23°C/73°F).
Preparation
- Use a NIOSH approved respirator and safety glasses.
- Mix components thoroughly for full cure properties.
- Test a small application for suitability.
Applying A Release Agent
Use Ease Release™ 200 or 205 for nonporous surfaces to prevent adhesion.
Measuring / Dispensing
Accurate measurements by volume or weight are crucial. Use clean containers.
Adding Color
Mix UVO™ color tints with Part A before adding Part B.
Mixing
Mix Parts A and B for at least 3 minutes, scraping sides and bottom. Use a shallow pan to extend pot life.
Adding Fillers
Pre-mix dry fillers with Part A before adding Part B.
Important
Mixed material generates heat. Avoid thick applications and use appropriate containers.
Applying
Apply two thin layers with a chip brush. Allow each layer to partially cure before applying the next.
Cure Time
Refer to specified cure times. Cured material can be sanded. Use a mask when sanding.
Heat Curing
Room temperature cure is sufficient, but mild heat can reduce cure time.
Painting
Cured material can be painted with acrylic enamel paints.
Removing Epoxy
Scrape uncured epoxy and clean residue with appropriate solvents.
