- Cure Instructions
Allow to cure at room temperature for 24 hours, or cure in an oven at one of these time/temperature options:
Temperature 65 °C 80 °C Time 2 h 1.5 h Moisture contamination with polyurethanes can create large bubbles on the surface and a lumpy appearance. For consistent curing results, ensure that the resin (part A) is dry before use and the mixture is kept dry during cure. If moisture contamination of part A is suspected, follow the steps below:
- Pre-heat part A at 65 °C for 2 hours. Mix the heated resin with the appropriate amount of hardener (do not allow the resin to cool as this may create condensation that wets the resin).
- Mix the 2 components together and cure in an enclosure that has a constant stream of nitrogen gas flowing through to keep the environment dry.

Technical Details & Test Data
- Viscosity vs. Temperature
- Mixing
- (Optional) Pre-heat part A to improve surface quality.
- Scrape settled material free from the bottom and sides of the part A container; stir the contents until homogenous.
- Measure 2 parts by volume of the pre-stirred part A, and pour into the mixing container. Ensure all contents are transferred by scraping the container.
- Measure 1 part by volume of the part B, and pour into the mixing container. Ensure all contents are transferred by scraping the container
- Thoroughly mix parts A and B together.
- (Optional) Put in a vacuum chamber at 25 inHg.
- Pour the mixture into a container holding the components to be protected.
- Blanket both parts with nitrogen if the material is not used up to prevent moisture.
- Close the part A and B containers tightly between uses.
Mixing >500 g at a time decreases working life and can lead to a flash cure. Limit the size of hand-mixed batches. For large production volumes, contact MG Chemicals Technical Support for assistance.
