INVISISIL TSE3033 is a high-performance, two-component, transparent heat curable silicone rubber. It is specifically engineered for critical electrical and electronic potting applications. This advanced formulation delivers robust protection and ensures reliable performance in demanding industrial environments. Furthermore, it offers exceptional primerless adhesion to a wide array of substrates, simplifying manufacturing processes and enhancing product longevity.
General Information of INVISISIL TSE3033
INVISISIL TSE3033 consists of two distinct liquid components, designated A and B. These components combine effortlessly in a convenient 1:1 mix ratio by weight. This low-viscosity characteristic is crucial; it permits excellent potting, ensuring thorough material penetration around intricate electronic components. The silicone rubber cures efficiently with heat, transforming into a durable, elastic, and transparent solid. Consequently, it provides superior environmental sealing, mechanical protection, and vibration dampening for sensitive assemblies. This material adheres effectively to diverse substrates, including various metals, plastics, glass, and ceramics, without requiring a primer. Importantly, its curing process generates no reactive by-products, thereby eliminating concerns regarding corrosion or degradation of encapsulated parts. This ensures long-term reliability for critical electronic systems.
