Description

This epoxy casting compound offers high heat resistance up to 177°C (350°F) with post cure. It is suitable for vacuum forming and thermoforming molds, foundry patterns, dies & fixtures, hard rollers, industrial parts, and high impact tools. It can also be used for encapsulation and bonding various surfaces.

Features

  • Low viscosity minimizes bubble entrapment.
  • Extra long working time of 3 hours.
  • Cures with negligible shrinkage, resulting in hard, strong, and heat-resistant castings.

Instructions

Use in a well-ventilated area and avoid breathing fumes. Wear safety glasses, long sleeves, and rubber gloves. Store and use materials at room temperature (23°C/73°F). Elevated temperatures reduce pot life. Properly measure and mix resin and hardener to achieve full cure properties.

Applying a Release Agent

  • Use Ease Release™ 200 or -205 for nonporous surfaces to prevent adhesion.
  • Brush the release agent with a soft brush, then apply a light mist coating. Let dry for 30 minutes.

Mixing

  • Pre-mix Part A for 2 minutes to a uniform consistency.
  • Stir Part B thoroughly before dispensing.
  • Accurate measurement by weight is required. Use a digital gram scale.
  • Mix Parts A and B thoroughly for at least 3 minutes, scraping sides and bottom of the container.

Vacuuming

  • Vacuum degassing is not required due to low viscosity.
  • If vacuuming, allow for 5 times volume expansion in the container.

Lowering Viscosity

  • Epic™ Epoxy Thinner can be added to improve flowability and reduce bubble entrapment.

Pouring

  • Pour into a rubber mold at the lowest point to achieve uniform flow and minimize air entrapment.

Cure Time

  • Cure for 24 hours followed by post-cure. Cured material will be hard and can be sanded.
  • Wear a mask when machining or sanding to prevent inhalation of particles.

Heat Curing

  • Heat cure in an industrial oven at 80°C (175°F) for 2 hours, then 150°C (300°F) for 3 hours.
  • Allow to cool to room temperature before use.

Painting

  • Can be painted with acrylic enamel paints. Let the paint dry fully before use.

Removing Epoxy

  • Scrape uncured epoxy from surfaces. Clean residue with E-POX-EE KLEENER™, lacquer thinner, acetone, or alcohol.
  • Follow safety warnings for solvents and ensure adequate ventilation.
