SILTRUST™ Silicone Products
Leveraging our successful development of silicone products for spacecraft and satellite solar arrays, Momentive has created the SILTRUST family of silicone products for terrestrial solar applications. This full line of encapsulants, adhesives, sealants and potting materials is engineered to endure the harsh environments in which solar panels operate, while generally improving the light-to-electricity conversion yield. These properties, plus greater general stress resistance, weatherability, corrosion protection, a longer life span and higher efficiency for crystalline silicone photovoltaic (PV) modules may potentially lead to a better return on investment and lower production costs for solar energy products.
SILTRUST encapsulants can be used to surround the fragile solar cells of the PV module with a very flexible, stress-dissipating silicone matrix that adheres well, yet does not pass on the level of mechanical stress the cells are subjected to in harsh environmental conditions. Likewise, SILTRUST adhesives, sealants and potting materials typically offer protection to sensitive components and durable adherence generally without primers to a variety of materials used in the PV industry, including aluminum frames, back sheets and glass.
In the PV manufacturing process, SILTRUST products may be incorporated at much lower temperatures than other products, thus potentially avoiding stress arising from differences in thermal expansion coefficients of a module's components. Curing speed is also typically faster than many other materials, resulting in an opportunity to shorten manufacturing cycles.
Because silicones do not absorb ultraviolet light, once the solar array is installed more sunlight reaches the surface of the solar cell, where it becomes available for conversion to electricity. The refractive index of SILTRUST encapsulant closely matches that of glass, generally reducing the energy-dissipating reflection of sunlight away from the solar cell.
SILTRUST products generally offer stability under extreme humidity, temperature and ultraviolet-radiation conditions over the life of a PV array installation.
Suggested applications for SILTRUST silicone products include:
- PV encapsulation
- Potting for solar junction boxes
- Frame seal adhesives for solar panels
- Rail bonding for solar panels

SILTRUST TSE3064-B is a two-component, silicone gel that can be used for electronics applications. This product cures quickly at room temperature to a soft, tacky gel with the addition of curing agent.
SILTRUST TSE3064H is a two-component, low viscosity, 1 to 1 mix ratio, dielectric silicone gel used primarily for electronics potting applications. Once mixed, this product cures at room temperature to a soft rubber / hard gel. The cure time can be accelerated with heat.
TSE3660 neutral alkoxy cure potting compound is a great candidate to consider for use in outdoor electrical applications.
SILTRUST™ LTR495
SILTRUST™ LTR495 is a two-component, thermally conductive silicone paste that cures at room temperature, and faster with the addition of heat, to form a soft, heat dissipating, low outgassing rubber
SILTRUST™ RTV534-LV Low Outgassing Adhesives
SILTRUST RTV534-LV is a two-component, room temperature cure silicone adhesive that features rapid tack free time, primerless adhesion to many substrates, extreme low temperature stability and low volatility.
SILTRUST™ RTV577-LV and SILTRUST RTV577-LV BLK Low Outgassing Adhesives and Sealants
SILTRUST RTV577-LV and RTV577-LV BLK are low volatile, two-component, room temperature cure silicone sealants with extreme low temperature stability. These RTVs come in white and black colors and have a thick paste consistency making them excellent candidates for horizontal, vertical and overhead applications with low sag.
