Product Introduction
Momentive SNAPSIL™ TSE3251 is a one-component, heat-curable, semi-flowable silicone adhesive developed for potting, dip-coating and encapsulation of electronic devices. This white, low-viscosity material adheres to many substrates without a primer and cures at elevated temperatures while offering a long working time at room temperature. After cure, SNAPSIL™ TSE3251 provides low shrinkage, non-corrosive bonding, strong dielectric performance and stable operation over a wide temperature range.
Momentive SNAPSIL™ TSE3251 Features
- One-component silicone adhesive, no mixing required
- Cures at elevated temperatures
- Low viscosity and semi-flowable consistency for potting and dip-coating
- Primerless adhesion to many types of substrates
- Low linear shrinkage with no cure by-products
- Non-corrosive to metals and sensitive substrates
- Good dielectric strength and high volume resistivity
- Outstanding performance over a wide temperature range
Momentive SNAPSIL™ TSE3251 Applications
- Coating and protection of hybrid ICs and printed circuit boards
- Dip-coating and encapsulation of electronic devices and assemblies
- General-purpose adhesive for metals, plastics, ceramics and glass
- Potting of components where semi-flowable silicone is preferred for coverage
- Applications requiring non-corrosive, electrically insulating silicone adhesives
