8810 is a black, tough, two-part polyurethane potting compound. It has a low mixed viscosity and excellent moisture resistance. In addition, it adheres strongly to a wide variety of substrates, including metals, composites, glass, ceramics, and many plastics. 8810 offers exceptional physical protection, and is designed for potting and encapsulating intricate electronic components and cable jointing boxes. 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 night. 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. Heat cure: Put in oven at 65 °C [149 °F] for 1 h. —OR— Put in oven at 80 °C [176 °F] for 45 min.
