0,00 ر.س
The Dowsil 3145 rtv mil a 46146 adhesive sealant clear is a one-part, non-flowing silicone adhesive/sealant that cures at room temperature through moisture exposure, providing high-strength, flexible bonding and reliable environmental protection. It is specifically engineered for electronics and industrial applications, offering excellent adhesion, durability, and resistance to thermal and mechanical stress.
Designed to meet MIL-A-46146 specifications, it is widely used for sealing, bonding, and protecting sensitive components such as printed circuit boards, housings, and electrical connections.
With its high tensile strength, excellent elongation, and non-sag consistency, the sealant ensures long-term performance in demanding environments, including exposure to moisture, vibration, and temperature variations.
