Polyurethane Potting Adhesive for Transformer Impregnation

Product Description

Transparent polyurethane sealant has low hardness, moderate strength, good elasticity, water resistance, mold resistance, shock resistance, transparency, as well as excellent electrical insulation and flame retardancy. It has no corrosive effect on electrical components and has good adhesion to metals such as steel, aluminum, copper, tin, as well as materials such as rubber, plastic, and wood. Transparent polyurethane sealant is used in situations that require transparent protection, such as sealing and protecting electronic components. It can provide excellent protection while maintaining transparency, making it easy to observe and detect the working status of electronic components.
 

Apply for Electronic Components Product features The JOMP 2608 A/B is a solvent-free, two-component casting resin, based on Polyurethane. The resin (A)  consists of organic compounds with hydroxyl-groups whereas the hardener (B) is based on isocyanates. By mixing both components in a ratio by weight of 100:16 a semi-tough casting resin is achieved via chemical reaction. The product exhibits no measurable change in volume after curing. The resin is used for filling, coating and casting. The product adheres well to metals and plastics. It contains flame retardant additives. l Low viscosity, fast curing in several hours l Excellent performance on low-temperature and aging l Excellent and stably electrical dielectric l Very low Water absorption l Good adhere to most metals and plastics Applications It  is  specifically  formulated  for  automotive  sensors,  switches,  transformers  and  other  electrical  devises requiring environments protection.
