Prostech distributes Momentive SILCOOL TIA219R, a specialized thermally conductive silicone potting material designed for electronic gap filling, featuring outstanding primerless adhesion and rapid heat cure.
GENERAL DESCRIPTION
Momentive SILCOOL TIA219R is a two-component, thermally conductive silicone potting material engineered to solve the most demanding heat dissipation and stress relief challenges in modern electronics. With its excellent flowability, this material seamlessly conforms to complex three-dimensional shapes, filling voids and cavities to establish a reliable thermal path that draws heat away from critical components. Upon curing, it transforms into a soft elastomeric rubber that effectively absorbs mechanical shock and relieves thermal expansion stresses.
A key advantage of SILCOOL TIA219R is its standard 0.5-hour work life, making it ideal for fast-paced automated dispensing lines that require a rapid transition from potting to curing. It achieves a complete cure at room temperature within 24 hours, or can be heat-accelerated in just 18 to 30 minutes to maximize manufacturing throughput. This product is officially distributed in Vietnam by Prostech, complete with comprehensive technical support and tailored solutions for your manufacturing processes.
FEATURES & BENEFITS
- **Thermal Conductivity of 1.9 W/mK:** Provides excellent thermal dissipation to efficiently transfer heat away from sensitive electronic assemblies, preventing hot spots and ensuring long-term device reliability.
- **Primerless Adhesion:** Adheres strongly to various substrates including metals, plastics, glass, and ceramics without requiring surface primers, streamlining production workflows and reducing material costs.
- **Soft Elastomeric Properties (Hardness Type A 25):** Delivers outstanding stress relief on delicate electronics, protecting fragile joints and components from thermal cycling and mechanical vibration.
- **Convenient 1:1 Mix Ratio by Weight:** Simplifies automated meter-mix dispensing configurations, reducing setup complexity and minimizing mixing errors on the production line.
