Seal and Protect
Locking out Dust and Moisture, Locking in Reliability
In PCB applications, customers demand dependable performance despite the harshest of environmental conditions.
Silicone adhesives, encapsulants and coatings from Dow Consumer Solutions offer a unique combination of thermal stability, flexibility and adhesion, ensuring durable seals that protect high-performance PCB system assemblies from damaging environmental factors, improving the value of your products and reducing total cost of ownership.
Available in a variety of viscosities and cure chemistries, our advanced silicone solutions deliver excellent unprimed adhesion to a variety of common substrates, including ceramics, reactive materials and filled plastics. After cure, they form rubbery elastomeric bonds that are more flexible than those offered by organic materials. Consequently, silicones help minimize mechanical stress on module components and interconnections caused by thermal cycling, impact and vibration. Many silicone adhesives, encapsulants and coatings from Dow Consumer Solutions retain this quality despite long exposure to extreme humidity or temperatures ranging from -45°C to 200°C. Silicone gel encapsulants offer even lower – virtually negligible – modulus, allowing them to flow around delicate electrical leads during thermal cycling to control stress.
