3M™ Scotchcast™ Electrical Resin 280 is a high-quality electrical resin that offers excellent thermal shock and mechanical shock resistance. This resin has a low gel point rating, which ensures a quick curing process when kept in warm environments. After curing, the resin exhibits a semi-flexible and good adhesion property, thanks to its high tensile strength. This electrical resin is ideal for applications that require excellent electrical insulating properties, thanks to its high dielectric strength. Additionally, it has a high flash point, which helps prevent any fire hazard due to quick ignition. One of the best features of this resin is its hydrolytic stability property, which minimizes quick chemical decomposition, thus providing long-lasting usage. It is MIL I 16923E Certified and RoHS 2011/65/EU Compliant, making it a reliable and safe choice for electrical applications. In summary, 3M™ Scotchcast™ Electrical Resin 280 is a high-quality, reliable, and safe electrical resin that offers excellent thermal shock and mechanical shock resistance, high dielectric strength, and hydrolytic stability property.
