MG Chemicals 8800 Black Flexible Urethane, 2-Part Potting Compound, 375mL Kit

8800 is a Black Flexible Urethane potting compound. It has a low mixed viscosity and maintains excellent flexibility at low temperatures. In addition, it adheres strongly to a wide variety of substrates, including metals, composites, glass, ceramics, and many plastics. 8800 is a cost-effective flexible potting option that provides exceptional physical protection and creates minimum stress on circuit boards and surface-mounted devices. It offers superior moisture resistance and is an ideal choice for harsh environment applications, especially salt water exposure and marine applications. Application Instructions- For best results, follow the procedure below. Manual mixing: 1. (Optional) Pre-heat part A to improve surface quality. 2. Scrape settled material free from the bottom and sides of the part A container; stir the contents until homogenous. 3. Measure 2 part by volume of the pre-stirred part A, and pour into the mixing container. Ensure all contents are transferred by scraping the container. 4. Measure 1 part by volume of the part B, and pour into the mixing container. Ensure all contents are transferred by scraping the container. 5. Thoroughly mix parts A and B together. 6. (Optional) Put in a vacuum chamber at 25 in Hg. 7. Pour the mixture into a container holding the components to be protected. 8. Blanket both parts with nitrogen if the material is not used up to prevent moisture. 9. Close the part A and B containers tightly between uses. Attention 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. Cure Instructions Room temperature cure: Let cure at room temperature for 24 h.
