How does unsaturated resin dry quickly in winter or wet weather?

1. Unsaturated resin adhesive belongs to anaerobic adhesive, and it is not easy to completely cure when it comes into contact with air. If the surface of the injection site is exposed, some liquid paraffin can be added.

Because the manufacturer adds a certain proportion of liquid wax to the resin, when the red and white materials are still cured after mixing, the liquid surface is covered with a thin layer of wax, which is isolated from the air, so the curing is normal.

2. Properly increase the ratio of initiator and curing agent to make it easy to generate heat, or increase the temperature of curing environment to improve the curing of unsaturated resin.

Brief introduction of unsaturated resin:

The resin first discovered by humans is a fatty substance extracted from the secretion of trees, such as rosin, which is why there is a "tree" before "fat". It was not until 1906 first synthesized phenolic resin that a new era of synthetic resin was opened up. 1942, the American rubber company first put into production unsaturated polyester resin, which was later called any unprocessed polymer resin. But it has nothing to do with trees for a long time. Resin is divided into thermoplastic resin and thermosetting resin. Meltable resins that can be cured by heating, melting and cooling are called thermoplastic resins, but after heating and curing, they are no longer irreversible and become insoluble and insoluble solids, which are called thermosetting resins, such as phenolic resins, epoxy resins and unsaturated polyester resins.
