Conformal coating agent

The Momentive product "TSE398" is a one-component, fast-curing, non-corrosive silicone adhesive sealant that cures with moisture in the air. After curing, it forms an elastic silicone rubber and exhibits excellent adhesion to copper, various metals, plastics, ceramics, glass, and more without the need for a primer. It has high fluidity and is designed for easy injection, making it widely applicable from waterproof sealing of electrical and electronic devices to general adhesive applications. - Non-corrosive: Complies with MIL-A-46146B corrosion testing. - Safe to use on highly corrosive metals such as copper and brass. - Fast curing: Tack-free time is only 10 minutes (at 23°C). - Low odor: Releases alcohol vapors during curing (significantly less odor compared to acetate-based products). - Primerless adhesion: Direct adhesion to a wide variety of substrates is possible. - Wide temperature range: Suitable for high and low temperature environments from -55°C to +200°C. - Excellent weather resistance, ozone resistance, and chemical resistance. - Outstanding electrical insulation properties: Ideal for sealing high-voltage components. - One-component formulation for easy handling.

Momentive's "TIA225GF" is a two-component addition reaction type liquid silicone material for heat dissipation. The main agent (Component A) and the curing agent (Component B) are mixed in a weight ratio of 1:1 and cured by heating (70°C for 0.5 hours) or at room temperature (23°C for 24 hours). After curing, it becomes a rubber-like elastomer with a thermal conductivity of 2.5 W/(m·K), forming an excellent heat path. This product is a liquid material with excellent thixotropic properties (shape retention), resulting in minimal dripping or smudging after application, making it easy to fill complex-shaped parts and gaps. It ensures stable thermal contact with high followability even on uneven bonding surfaces and narrow gaps, which are difficult to address with conventional thermal interface materials. By containing high-fill fillers, it achieves both high thermal conductivity and electrical insulation, making it suitable for applications requiring high reliability, such as power modules and communication boards.

"When in doubt about what to use, start with this" — The reason why this product continues to be chosen by field engineers In the manufacturing and research and development environments of electrical and electronic devices, there are many situations where silicone-based adhesives and sealants need to be selected. When multiple requirements overlap—such as needing heat resistance, wanting to avoid corrosion on certain metals, needing fast curing, or wanting to keep costs down—searching for a product from scratch each time is a waste of time. Many engineers likely have a trusted go-to product that they use when unsure. For many years, this position has been held by Momentive's TSE39×5 series (TSE3925, TSE3975, TSE3995). We will explain in detail, along with technical backing, why this series continues to be a bestseller in many fields.

SnapSil TN8000 is a one-component, fast-curing, non-corrosive silicone adhesive sealant provided by Momentive Performance Materials. It utilizes an alkoxy neutral curing system that reacts with moisture in the air, forming a silicone rubber that combines flexibility and elasticity after curing. This product takes the form of a thixotropic (shear-thinning) paste, demonstrating moderate flowability during application, while minimizing sagging after application on vertical or inclined surfaces, making it easy to work with. Additionally, since it is an alkoxy curing type, it does not emit corrosive gases during curing. It can be safely used in applications involving easily corroded metal materials such as copper and precision electronic components. Features: - Fast curing and alkoxy neutral curing: Cures quickly at room temperature, improving work efficiency. - Primerless adhesion: Exhibits excellent adhesion without the need for a primer on many substrates. - Long-term adhesion reliability: Maintains high adhesive strength even in humid environments. Adhesive performance remains stable after long-term aging. - Excellent electrical insulation: Has high volume resistivity and dielectric breakdown voltage, making it suitable for insulating and sealing electrical and electronic components. - Flame retardant certification: UL94 HB certification obtained.
