3M Scotchcast Electrical Resin 281 is a 2-part, oven curing, liquid resin that is used for electronic and electrical applications requiring the highest level of protection. This filled epoxy-based resin has a low viscosity and impregnating property, making it easy to infuse on any surface. It is useful for applications that include filling, patching, insulating and more.
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 an 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.
