3M™ Scotchcast™ Electrical Resin MR283F075 has a low gel point rating to ensure a quick curing process in warm environments. The filler that is used in the electrical resin is formulated to prevent shrinkage and stresses. It is ideal for applications that need excellent thermal shock and mechanical shock resistance. Its high dielectric strength offers good electrical insulating property to the resin. It has a high flash point, helping prevent any fire hazard in electrical components due to quick ignition. Since the resin exhibits a hydrolytic stability property, it minimizes quick chemical decomposition, thus providing long lasting usage. RoHS 2011/65/EU Compliant.
