Applications:
1. As epoxy coupling agent, it is used in polysulfide-based and metal-filled epoxide resinous material.
2. Improve the adhesion between inorganic stuffing , base material and resin, hence improve the mechanical strength, electric property of composite materials and high retention in wet state.
3. Improve the electrical properties of many composite materials , invluding inorganic-filled Nylon and PBT. It can be widely used in many fillers and substrates such as clay, talcum, tricalcium silicate and so on.
4. Avoid the need of independent primer in polysulfide and polyurethane sealant and sealing compounds.
5. Improve the adhesion of double-component epoxy sealing agent, acrylic acid latex, sealing agents polyamino ester, epoxy resin.
