Master Bond has recently released its new product, Supreme 42HT-2ND Black, a two-part, non-drip epoxy system designed for bonding, sealing and coating applications.
Supreme 42HT-2ND Black is an electrically insulative epoxy with a volume resistivity greater than 1014 ohm-cm. This compound has a Shore D Hardness of 75 – 85 at 75°F (23.8°C) and can withstand rigorous thermal cycling. Also, the epoxy has passed damp heat reliability testing for 1,000 hours at 85°C and 85% relative humidity. Supreme offers a high strength profile, with a tensile strength of 9,000 psi – 10,000 psi and a tensile modulus of 300,000 psi – 350,000 psi at 75°F.
Master Bond’s new epoxy is capable of withstanding temperatures up to 450°F (232°C), and provides a glass transition temperature (Tg) of 130°C – 135°C. The material also meets NASA low outgassing standards and Master Bond recommends this product for applications that require vacuum compatibility.
With a mix ratio of 100 to 40 by weight or 100 to 50 by volume, this paste consistency material can be easily applied with the use of a gun dispenser or spatula. The epoxy cures at ambient temperature within a 2 – 3 day period. Adding heat will not only speed up the curing process, but will also optimise the overall performance properties of the product. Supreme 42HT-2ND Black is available in standard packaging, double barrel cartridges for gun kits, as well as pre-mixed and in frozen syringes.
