This product has good thixotropy and is especially suitable for LED lamp dam. It can be used with additive silicone rubber. It does not poison platinum catalyst, is non-corrosive to metal, and has good adhesion to many
substrates (such as aluminum, copper, Steel, glass, PC, PET, ABS Etc.) Excellent weatherability, ozone resistance, high and low temperature resistance, high temperature and high humidity resistance and chemical resistance.
How to use: Thoroughly clean and dry the surface of the bonded substrate before use. Uncured dam glue can irritate the eyes, wear protective glasses when using; avoid contact with the skin for a long time. May cause irritation; must be kept at all times Enough ventilation.
Special use: It is suitable for the inner layer bonding of PTC. The aluminum substrate of PCB is bonded to the dam. It can also be used as the bonding of electronic and electrical instruments and instrument components to prevent moisture, shock, insulation and sealing. Fast surface cure, only about 10 minutes (in temperature)
Tested at 25 ° C and 50% humidity).
