If you're looking for a low-viscosity encapsulant with excellent adhesion and low-temperature properties, LOCTITE® STYCAST 2850KT BL is a great pick. This epoxy-based encapsulant is uniquely designed for heatsink replacement in non-integrated electrical components and assemblies. It can resist thermal shock and impact, making it ideal for high-voltage applications where surface arching or tracking is a concern. LOCTITE® STYCAST 2850KT BL is tested to perform seamlessly in applications with an operating range of -85°F (-65°C) to 221°F (105°C) and is compatible with a variety of LOCTITE® catalysts. We always recommend contacting a local technical service representative for assistance and recommendations on mixed properties.
