Dowsil 738 RTV WHITE Electrical Sealant

DOWSIL 738 RTV White Electrical Sealant White Electrical Sealant is a one-part, moisture curing silicone adhesive designed for electrical sealing, bonding, and protection of sensitive components. The sealant cures at room temperature to form a durable elastomeric rubber that provides reliable adhesion and long-term flexibility.

This non-flowing RTV silicone adhesive is widely used in electrical and electronic assemblies where components require environmental protection and stress relief. Once cured, the sealant maintains high elongation properties, helping absorb mechanical stress and vibration while protecting assemblies from moisture and contamination.

DOWSIL 738 cures in typical ambient humidity conditions without the need for ovens or special curing equipment, making it suitable for production, maintenance, and repair applications across a wide range of industries.
