3M™ Scotchcast™ Electrical Resin 281 has a low gel point rating to ensure a quick curing process when kept in warm environments. The high tensile strength of the resin exhibits a semi flexible and good adhesion property after curing. It is ideal for applications that need excellent thermal shock and mechanical shock resistance. Its high dielectric strength offers excellent electrical insulating property to the resin. It has a high flash point, helping prevent any fire hazard due to quick ignition. Since the resin exhibits a hydrolytic stability property, it minimizes quick chemical decomposition, thus providing long lasting usage. Mil 16923 Certified and RoHS 2011/65/EU Compliant.
