The U69-42 polyurethane resin is a two-liquid component insulating material available in both white and black color options. By combining the base resin with the U69-42B catalyst at a 100:16 weight ratio, the mixture climbs quickly in viscosity to provide robust, thick protection for printed circuits. This polyurethane system cures rapidly, offers superior abrasion resistance, and ensures components remain unstressed due to its flexible nature.
U69-42 Polyurethane Resin Features:
Formulated with a viscosity of 1100 cSt and a specific gravity of 1.50.
Performs effectively across an operating temperature range of -50°C to +120°C.
Cures to a stable Shore D35 hardness.
Delivers high-level electrical insulation with a 25 kV/mm dielectric strength.
Characterized by a pot life of 15 to 20 minutes and a gel time of 30 minutes.
U69-42 Polyurethane Resin Applications:
Designed to insulate and protect printed circuit board components against severe environmental conditions, mechanical shocks, and thermal shocks.
Applied to facilitate the safe operation of electronic subsets that are completely immersed in solvents, water, or gases.
Employed extensively in the manufacturing of industrial, spatial, military, medical, and automotive electronics.
