What is the ratio of GFRP resin to curing agent?
The proportion of curing agent of ordinary polyester resin is between 1 and 3%, which depends on the requirements of curing time, the addition amount of accelerator, environmental temperature, humidity and other conditions.
The effect of accelerator on curing time was more significant.
When the humidity is high and the temperature is low, the proportion of curing agent should be appropriately increased.
Curing time is too short, easy to cause severe contraction and deformation of the product, at the same time will appear dark yellow.In addition, the curing time is too short, which will lead to the concentration of solidification and heat release and shorten the service life of the mold.
