FAQ
- What's means A& B of epoxy resin?
- A means epoxy resin , B means Curing agent
- What is the mixing ratio of Part A & Part B?
- The ratio varies for every epoxy resin grade. We provide recommended mixing ratios for each type of epoxy resin.
- What will happen if the mixing ratio of epoxy resin Part A and curing agent Part B is incorrect? Can this epoxy resin still be used?
- A ratio deviation exceeding 3% will lead to incomplete curing, sticky surface and sharp drop in mechanical strength of epoxy resin. The mismatched mixture cannot be remedied and must be discarded to prepare new epoxy resin.
- How long is the shelf life of epoxy resin?
- The shelf life of epoxy resin is 10 months under cool and shaded storage. Avoid direct sunlight and low-temperature crystallization. Fully stir Part A before mixing to use epoxy resin
- What's the packing of epoxy resin
- We have two packing , one is IBC packing , 1000kg per drum ,anther is Iron drum :200kg per drum
- What's the delivery time of epoxy resin
- IBC packing : 7-10 days Iron drum: 25- 30 days
- Can you customize exclusive epoxy resin formulas according to working conditions?
- Custom epoxy resin is fully supported. We adjust viscosity, gel time, flame retardancy, heat resistance, shrinkage and insulation of epoxy resin to match clients' production processes, performance indicators and compliance standards.
- Can I get epoxy resin samples for testing?
- Free epoxy resin samples start from 5kg for trial test.
- What' s the MOQ?
- MOQ is one ton
- What industries can epoxy resin be applied to?
- Our epoxy resin is widely used in aerospace, automotive lightweight, rail transit, wind power blades, ships, hydrogen storage cylinders, pultruded insulating profiles, sports equipment and other composite material fields.
- How to clean tools contaminated with uncured and fully cured epoxy resin?
- Clean uncured epoxy resin on tools with acetone or anhydrous ethanol. Fully cured epoxy resin is solvent-resistant and can only be removed by mechanical polishing.
- Can I mix epoxy resin Part A/B from different brands?
- Never match Part A and curing agent B of epoxy resin from different brands.
- Can one epoxy resin fit different molding processes like RTM, pultrusion and vacuum infusion?
- It is not recommended. Each epoxy resin is designed with exclusive viscosity, gel time and exothermic peak for specific processes to guarantee fiber wet-out and stable production efficiency.
