Material Notes:
EP 82, “Powered by Reactamine® Technology”, is a new hydrophobic silicone polyurea. The product is characterized by its low viscosity and ability to readily blend with polyisocyanates. It may be processed to produce elastomers of varying hardness. Water absorption of this product is shown to be five to ten times lower than regular polyureas. These elastomers were subjected to a severe hydrolysis test which involves immersing them in water at 90 °C. for a period of 28 days. A similar test has been used for military applications, where specimens are conditioned for 28 days at 100 °C and 95 % relative humidity, stimulating about 10 years of service at 35 °C. and 95 % relative humidity. The EP 82 shows excellent resistance to oxidizing agents, such as those used to treat swimming pools. Thus, chlorinated water resistance of elastomers produced from EP 82 and isocyanates, are superior to those obtained from a conventional polyurea. Applications: electrical encapsulation, swimming pool filter end-caps, re-enterable encapsulants, cable splicing, and others where the polyurea is exposed to a hard, moisture laden environment, requiring hydrophobic resins that can provide pli necessary resistance to (i) water ingress, (ii) degradation of physical properties and (iii) corrosion of electrical components.Part of the Amber Chemical Group.
