Textile coating process detailed explanation
- 2024-08-23 17:32:42
- admin
Before the textile coating, it is necessary to pretreat the textile surface to ensure the adhesion and quality of the coating. Common surface treatment methods are: cleaning, degreasing, polishing and so on. Cleaning can be done with hot water or solvents, degreasing can be done with alkaline or acid degreasing agents, and polishing is done by mechanical removal of surface hair. The choice of coat...

Features of water based acrylic resin
- 2024-09-25 16:52:13
- admin
1.Type: There are three main types of water-based acrylic resins, including emulsion, water dispersion and aqueous solution. The emulsion is synthesized by emulsifying olefins in water under the action of water-based free radical initiator. The aqueous dispersion is synthesized by free radical solution polymerization or stepwise solution polymerization. Aqueous acrylics are directly soluble in wat...
