WATERFORD, N.Y. -- Momentive Performance Materials had featured a portfolio of products that can help enable long durability and cost-effective manufacturing for solar module assembly at the Solar Power International Show in Las Vegas, NV.

SilTRUST* SP100 Adhesive - Latest addition to High-performance Product Range

SilTRUST* SP100 adhesive is the latest in Momentive's growing family of high-performance products for solar applications. These include frame sealing solutions, junction box and back sheet sealing materials, junction box potting, PV module encapsulants, and sealing materials for thin film technology, CPV technology and rail bonding.

SilTRUST SP100 adhesive was developed as a one- component condensation cure silicone rubber for sealing. This adhesive cures at room temperature to form an elastic, flame retardant rubber and adheres to various types of materials such as metal, plastics, glass and ceramics, without the use of primers. It has excellent storage stability, stable properties after high temperature & humidity (85C/85%RH) and heat age.

The low cost silicone grade comes with a complete UL listing including flame retardency, dielectric properties and certification for indoor and outdoor adhesion to glass, aluminum, mPPE from -35CF – >110C to allow PV module manufacturers to quickly adopt this new grade. White, gray and black version SilTrust SP100 adhesive pastes are available.

Properties of SilTRUST SP100 Adhesive

  • SilTRUST SP100 adhesive generally has fast room-temperature curing capabilities, thanks to its neutral alkoxy tin-free curing system. It can provide superior primerless adhesive properties to glass, aluminum, common junction box plastics and backsheets.
  • Its superior shelf life has been noted to be stable with adhesive properties after 85° C/85% RH conditioning when typically compared to competitive grades, and has shown excellent color stability after accelerated UV and heat aging.

Potential applications for SilTRUST SP100 adhesive include

  • Primerless adhesives for glass, aluminum and plastics
  • Solar assemblies
