3M™ Scotchcast™ Electrical Resin 226 is a versatile and reliable solution for a wide range of electrical applications. With a low gel point rating, this resin cures quickly and effectively at room temperature, ensuring a strong and durable bond.

One of the key benefits of this resin is its high-tensile strength, which provides excellent flexibility and adhesion after curing. This makes it ideal for applications that require resistance to thermal and mechanical shock. Additionally, the resin has a high dielectric strength, which ensures excellent electrical insulation properties.

Another important feature of 3M™ Scotchcast™ Electrical Resin 226 is its high flash point, which minimizes the risk of fire hazards due to quick ignition. The resin also exhibits hydrolytic stability, which helps to prevent quick chemical decomposition and ensures long-lasting usage.

This product is ASTM Approved, MIL-I-16923E Certified, and RoHS 2011/65/EU Compliant, making it a safe and reliable choice for a wide range of electrical applications.
