Product Description
Product Name: Epoxy Vinyl Ester Resin HS-4433
1. Brief Introduction:
HS-4433 is a regular bisphenol A epoxy vinyl ester resin which is used in the production of many kinds of FRP, such as concrete manhole, anti-corrosive lining, FRP tank, electrical insulating materials and frp mold. HS-4433 is suitable for hand lay-up, pultrusion, RTM, and filament winding process, etc. It also has good mechanical strength, toughness and great heat resistance and corrosion resistance.

2) Post curing: RT×24hrs +80ºC×4hrs(tensile and impact test); RT×24hrs +120ºC×4hrs(flexural, hardness and HDT test);
4. Recommended using ratio(weight ratio):
| A |
Resin/HS-926/ButanoxLPT |
100/0.3~1.0/1.0~2.0 |
| B |
Resin/HS-935/V388 |
100/1.0~2.0/1.2~4.0 |
| C |
Resin/DMA/BPO |
100/0.15~0.4/1.0~3.0(absolute content) |
Note:
1) The using ratio listed above is suitable for 15~30ºC. Before use in large doses, please confirm the appropriate adding proportion according to the site environment.
2) HS-926: cobalt naphthenate or cobalt iso-octoate, available content is 6%;
HS-935: cobalt iso-octoate, available content is 1.5%;
Production made by the former is more beautiful.
5. Storage:
1) Avoid exposure to heat sources such as direct sunlight or steam pipes. Stored in a dry place at temperatures below 25ºC.
2) Keep sealed to prevent moisture pick-up and monomer loss. Prolonged storage outside of recommended conditions can influence liquid resin properties like viscosity and gel time.
3) Transportation should fit the State Council "Chemistry Dangerous Articles Safety Management Regulations". Because it contains styrene monomer, it is hazardous and inflammable.
