APPLIANCES
Momentive’s high performance materials help to redefine what is possible in appliance manufacturing whether safeguarding appliances from bumps and vibrations, PCB protection, or thermal management. With products including thermally conductive greases, heat resistant adhesives, conformal coatings, and transparent potting materials, Momentive’s silicone materials aim to improve reliability, performance of appliances, and enable design flexibility.
AUTOMOTIVE
Momentive develop advanced silicones for the most demanding challenges in the automotive industry, from making cars lighter, more durable and environmentally friendly, to battery solutions. Their silicones provide thermal management solutions, ideal for extreme environments, maintaining flexibility and strength in both high and low temperatures. As the automotive industry evolves new solutions are needed for electric vehicles including cable and charging system solutions. Momentive’s advanced material solutions play an essential role in the vehicles of today and tomorrow.
ELECTRONICS
As systems become smaller and circuit densities become greater, advanced solutions are needed to enable the next generation of electronics. From electronic potting silicones and encapsulation products, to adhesives, additives, hard coats and packaging, Momentive offers silicone sealants and fast cure silicone adhesives for high productivity assembly and solutions for electronic components that can allow design flexibility and help provide long term component reliability under harsh operating conditions.
MOMENTIVE BRANDS & PRODUCTS
Snapsil™ Electronics Bonding
Enable electronics and electrical component manufacturers to optimise production speed and adhesion quality without exposing sensitive components to potentially damaging heat-cure processing. These room-temperature, condensation-cure adhesives form a strong bond to most substrates, including metals, polymer resins and glass.
SilCool™ Thermal Management
Thermal interface materials, characterised by excellent thermal conductivity and consistent, long term heat transfer performance. This range includes grease compounds, adhesives, encapsulants, and potting comounds. Excellent candidates for electronic and other applications where thermal management and high heat transfer are critical.
SilGrip™ Pressure Sensitive Adhesives
This range of silicone pressure sensitive adhesives (PSA) from Momentive Performance Materials which adhere to a wide variety of surfaces, are generally reliable over a broad temperature range, and typically thoughtfully balance tack and peel properties depending on the application.
Addisil™ Heat Cure Bonding
Excellent where industries require high quality heat cured rubber products. These offer high mechanical performance, a broad range of durometers, and one component ready to use options. Addisil™ materials utilise a platinum catalyst, which may be desirable in applications where regulatory compliance, transparency and mechanical performance are important.
Siltrust™ Encapsulants & Coatings
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. Offering stability under extreme humidity, temperature and ultraviolet-radiation conditions.
INVISISIL™ Optical Bonding
Offering both the optical clarity and protection required by advanced optical applications, including LED lighting materials. Delivering high optical stability and light transmittance, INVISISIL products can also contribute to the durability and reliability of devices through their long term resistance to yellowing or delamination.
