Information

LOCTITE® STYCAST 2850KT BL is a low-viscosity epoxy-based encapsulant with excellent adhesion and low-temperature properties. It is uniquely designed for heatsink replacement in non-integrated electrical components and assemblies, and can resist thermal shock and impact, making it ideal for high-voltage applications where surface arching or tracking is a concern. It is tested to perform seamlessly in applications with an operating range of -65°C to 105°C (-85°F to 221°F) and is compatible with a variety of LOCTITE catalysts.
