Full series are A/B epoxy resin with finely classified grades. Special models are developed for different processes, working conditions and industries instead of a single general-purpose epoxy resin.
Full-process compatible: Our epoxy resin fits all composite molding processes including RTM/WCM, filament winding, vacuum infusion, prepreg molding, pultrusion, hand lay-up and UV curing.
Wide viscosity range: Our epoxy resin covers low, medium and high viscosity grades to meet various construction requirements of composite production.
Flexible curing performance This epoxy resin provides fast curing and ultra-long gel time options, balancing production efficiency and long operation window for complex parts.
Wide application : Our epoxy resin serves multiple industries including aerospace, automotive, rail transit, wind power and shipbuilding.
Customized solutions supported: We provide tailored composite system epoxy resin based on customers' production processes, performance standards and compliance demands.
CCS certified : Multiple grades of our epoxy resin have obtained China Classification Society certification for marine applications.
Complete heat resistance gradient The epoxy resin covers general heat resistance 75~145 deg C, medium high temperature 135~165 deg C and ultra-high heat resistance 195~230 deg C.
Long shelf life: Compared with unsaturated and vinyl ester resin, our epoxy resin has a longer shelf life up to 10 months.
Fast delivery: Packed in IBC totes, our epoxy resin can be delivered within 7-10 days to shorten customers' waiting cycle.

Product Q&A
Q:What's means A& B of epoxy resin?
A:
A means epoxy resin , B means Curing agent
Q:What is the mixing ratio of Part A & Part B?
A:
The ratio varies for every epoxy resin grade. We provide recommended mixing ratios for each type of epoxy resin.
Q: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:
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.
Q:How long is the shelf life of epoxy resin?
A:
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
Q:What's the packing of epoxy resin
A:
We have two packing , one is IBC packing , 1000kg per drum ,anther is Iron drum :200kg per drum
