Acc Silicones Grey Potting Compound Silicone Dual Cartridge 250 g QSIL-553

Acc Silicones QSIL-553 is a high-performance grey potting compound silicone supplied as a dual cartridge, 250 g package. This two-component addition-cure silicone elastomer is thermally conductive with a conductivity rating of 0.68 W/mK, ideal for electronic assembly potting applications requiring thermal management.

The compound cures fully in 24 hours and has a Shore A hardness of 32, providing a rubber-like protective layer that resists shock, vibration, and contamination from environmental factors. Its operating temperature range from -55°C to a maximum of 260°C ensures suitability for demanding industrial environments including electronics manufacturing, laboratory settings, and specialized industrial insulation tasks.

The twin pack cartridge simplifies the mixing process with two colours aiding in visual confirmation of thorough mixing, eliminating the need for weighing or external equipment. Its moderately low viscosity provides ease of application while maintaining long pot life and fast curing upon heating.

Acc Silicones QSIL-553 is RoHS compliant and UL 94 approved, meeting stringent safety and environmental standards required in industrial applications. The material is non-corrosive and silicone based, allowing for easy repair and continued performance over time.

This grey potting compound is specifically engineered to offer reliable electrical insulation and mechanical protection in electronic and electrical assemblies. Its specific gravity of 1.60 assures consistent volumetric performance during curing.

The dual cartridge packaging ensures easy, clean mixing and application. Offers thermal conductivity of 0.68 W/mK for heat dissipation. Operates effectively from -55°C up to 260°C. Provides strong mechanical protection against shock and vibration.

Cures fully within 24 hours with a Shore A hardness of 32. Non-corrosive and repairable silicone elastomer. Complies with RoHS and UL safety standards. Specific gravity of 1.60 for consistent density.
