Instructions

Preparation

  • Use in a well-ventilated area and avoid breathing fumes. A NIOSH-approved respirator is recommended.
  • Wear safety glasses, long sleeves, and rubber gloves to minimize skin contact.
  • Store and use materials at room temperature (23°C/73°F). Elevated temperatures will reduce pot life.
  • Ensure proper measurement and thorough mixing of resin and hardeners for full cure properties.
  • Conduct a small test application to determine suitability for your project.

Applying A Release Agent

  • Use Ease Release™ 200 or 205 on non-porous surfaces to prevent adhesion.
  • Brush the release agent lightly over all surfaces, follow with a mist coating, and let dry for 30 minutes.

Pre-mixing Part A

  • Reconstitute fillers by pre-mixing Part A thoroughly using a turbine mixer or similar for 2 minutes, followed by hand mixing for 1 minute.

Measuring / Dispensing

  • Mix 100 parts resin to 12 parts hardener by weight using an accurate scale.
  • Ensure mixing tools and containers are clean and dry.
  • Combine resin and hardener, mixing thoroughly for 3 minutes, scraping the container's sides and bottom.

Adding Color

  • Color with UVO™ or IGNITE™ colorants by pre-mixing with Part A before adding Part B.

Mixing

  • Ensure utensils are clean and free of contaminants. Mix Parts A and B for at least 3 minutes, scraping sides and bottom.

Adding Fillers

  • Add dry fillers by pre-mixing with Part A before adding Part B.

Lowering Viscosity

  • Add Epic™ Epoxy Thinner to improve flow-ability and reduce bubble entrapment.

Increasing Flexibility

  • Add Flexer™ Epoxy Flexibilizer to lower the durometer and make the epoxy softer.

Pouring

  • Pour into molds at the lowest point to minimize air entrapment.

Cure Time

  • Refer to specified cure times. Cured material will be hard and can be dry sanded.

Heat Curing

  • Heat cure at 80°C (175°F) for two hours, followed by 150°C (300°F) for three hours. Allow to cool to room temperature.

Painting

  • Paint with acrylic enamel paints after curing. Let paint dry fully before use.

Removing Epoxy

  • Scrape uncured epoxy and clean residue with E-POX-EE KLEENER™, lacquer thinner, acetone, or alcohol.
