2. Application
502 has good compatibility with other amine curing agents. It is completely transparent at a temperature of about 0 degrees. It is mainly used in casting and electronic potting, composite materials, epoxy glass fiber reinforced plastic products, two-component epoxy resin adhesives, epoxy resin coatings, and dilution of high-viscosity polyamide curing agents, etc.
3. Storage and packaging
Stored in a cool and dry place with ventilation and can be sealed for 12 months.
Package:190kg/ iron drum.
