Taihei Kasei HVF-1
HVF-1 is a high-solids, high-viscosity fluoropolymer coating and repair compound developed by Taihei Kasei Co., Ltd. Its formulation is mainly based on fluoroelastomer and is designed with a very low level of low-molecular cyclic siloxanes. According to the latest product catalog, the low-molecular cyclic siloxane content is controlled to 15 ppm or less, making HVF-1 suitable for environments where siloxane contamination is undesirable. HVF-1 is supplied as a white paste with a viscosity of approximately 150,000 mPa·s at 25°C and a non-volatile content of approximately 65%. Its high viscosity allows thick coating and localized repair, making it suitable for sealing joints, flanges, leakage areas and deteriorated equipment surfaces.
