Product Description
LOCTITE® FREKOTE® B-15 is a clear, colorless, one-part, solvent-based polymeric mold sealer formulated for preparing composite and metal molds with micro-porosity, minor surface scratches, or other small imperfections. It forms a base coat that seals the mold surface before application of a compatible FREKOTE® mold release agent. The sealer provides high thermal stability and is formulated to avoid contaminating transfer to molded parts, supporting consistent mold preparation and release-system performance.
