TONSAN Adhesives Corporation has built a team of skilled research chemists and technical engineers to design the highest quality Sealants and Adhesives for the Photovoltaic Cell Industry. They are the leading producer of PVC adhesives and sealants in China with an 80% market share.

Silicone Sealant 1527 and 1528 were developed specifically for PV Module assembly. They exhibit excellent adhesion to back sheet materials such as TPT, PVDF, PET, and BBF. Sealants 1527 and 1528 maintain crucial mechanical and electrical properties over the most extreme conditions. Their elastic and bonding properties make them the ideal choice for a PV module that will withstand damage caused by weather.
  • Excellent heat and weather resistance
  • Good Adhesion to several key materials
  • Excellent electrical insulation
  • Fast-curing
  • Ideal for automatic dispensing
