Single Component Alcohol-Free Silicone Adhesive Sealant for Electronic Components Bonding

Product Description

UB-511 is a one-component, white paste, alcohol-free, room temperature cure silicone rubber designed for bonding and sealing. It has moderate viscosity, excellent thixotropy, good extrudability and is easy to apply. This silicone sealant provides excellent, non-corrosive adhesion to metals, plastics, ceramics and glass without the need for primer. It cures rapidly in air to form a stable elastic rubber with excellent heat/cold resistance, excellent electrical insulation and long-lasting weather resistance. It is widely used for reliable bonding, sealing and insulation in electronics, industrial, construction and everyday applications.
