Material Notes:
Description: Master Bond Polymer Compound EP45HTQ is a two component quartz filled, epoxy compound for high performance structural bonding and casting. It is suitable for applications where long term exposure to temperatures from -60° to +500°F is required. lt is 100% reactive and does not contain any solvents or diluents. It is formulated to cure rapidly at elevated temperatures. It has a convenient 100 to 30 mix ratio, by weight. It produces high strength bonds at both ambient and elevated temperatures. Master Bond EP45HTQ can be applied without sagging or dripping on vertical surfaces. It produces durable high strength and tough bonds which are remarkably resistant to thermal cycling and chemicals including water, oil and most organic solvents over the exceptionally wide temperature range of - 60°F to more than +500°F. It also produces superior seals & high quality pottings. Adhesion to metals, glass, ceramics, wood, vulcanized rubber and many plastics is excellent. The hardened compound is an electrical insulator. Color of Part A is tan, part B is tan. Master Bond EP45HTQ is widely used in aerospace, electronic, electrical, computer, construction, metal working, appliance, automotive and chemical industries.Product Advantages: Convenient mixing: 100/30 mix ratio by weight Easy application: contact pressure only required for cure, compound spreads evenly and smoothly; no drip application feature Convenient cure schedules: long pot life at room temperature, requires elevated temperature cure. High bonding strength to similar and dissimilar substrates Superior durability, thermal shock and chemical resistance Reactive and does not contain any solvents or diluentsResists ETO sterilization, chemical sterilants and repeated autoclaving High compressive strength Resistance to radiation up to 10^10 radsInformation provided by MasterBond®
