MG Chemicals 832WC - Water Clear Epoxy

832WC is a rigid, 2-part, clear epoxy resin that offers extreme environmental, mechanical and physical protection for printed circuit boards and electronic assemblies. It is designed for applications where high clarity is required. It does not yellow when exposed to UV light; it maintains clarity in applications with service temperatures of up to 65 °C and intermittent exposures of up to 100 °C. It can be used for underwater applications such as potting swimming pool lights. It is also a good choice for casting resin.

Mixing
  1. Measure 2 parts by volume of the part A and pour into the mixing container. Ensure all contents are transferred by scraping the container.
  2. Measure 1 part by volume of the part B and pour into the mixing container. Ensure all contents are transferred by scraping the container.
  3. Thoroughly and gently mix parts A and B together. Avoid introducing air bubbles.
  4. To de-air, let sit for 15 minutes or put in a vacuum chamber at 25 inHg for 2 minutes.
  5. If bubbles are present at the top, break them gently with the mixing paddle.
  6. Pour the mixture into a container holding the components to be protected.
  7. Close the part A and B containers tightly between uses to prevent skinning.

If crystallization/solidification occurs, reconstitute the product by warming to between 55 and 65 °C until it becomes fully re-liquified. Let the material cool to room temperature before mixing, to prevent flash cure.

Mixing >500 g at a time decreases working life and can lead to a flash cure. Limit the size of hand-mixed batches.

Cure Instructions

Allow to dry at room temperature for 24 hours, or after letting sit for 10 minutes, cure the coating in an oven at one of these time/temperature options:

Temperature 65 °C 80 °C 100 °C
Time 2 h 1 h 30 min
