Alfa Chemistry offers novel adhesion promoters based on modified epoxy resin prepolymer. The series of products is a prepolymer system based on a combination of epoxy resins, fatty acids and (methyl) acrylates, and can be used as additives giving excellent adhesion and corrosion protection in systems like water-based direct-to-metal (DTM), solvent-based DTM systems, high solid/solvent-free systems cured by peroxide or driers, solvent-free UV-curable DTM systems. In this series of products, we have developed and produced four types of this product (HG-CohesivePro 5001, HG-CohesivePro 5002, HG-CohesivePro 5003 and HG-CohesivePro 5004), among which HG-CohesivePro 5001 and HG-CohesivePro 5002 are modified bisphenol A epoxy resin and modified bisphenol F epoxy resin, respectively, HG-CohesivePro 5003 and HG-CohesivePro 5004 are the products obtained by further silane modification of the modified bisphenol A epoxy resin and modified bisphenol F epoxy resin. Each product has completely different properties, performances and applications. Details of each product are described below, please see to find the suitable product for your projects.
