3M Scotchcast Electrical Resin 226 (11 lb)
  • Manufacturer:3M
  • Part Number:7000057516
3M Scotchcast Electrical Resin 226 is a 2 part, liquid type product that is useful for electronic and electrical applications requiring the highest level of protection. This unfilled, castro based polyurethane resin has a very low viscosity property, which makes it easy to infuse on any surface. It is useful for wide range of electrical and electronic potting and casting applications.3M™ Scotchcast™ Electrical Resin 226 has a low gel point rating to ensure curing at room temperature. The high tensile strength of the resin exhibits a 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, preventing 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. ASTM Approved, MIL I 16923E Certified and RoHS 2011/65/EU Compliant.
