Carefully crafted water-based ecological resin for you!
PUS-65
PUS-65 Waterborne Polyurethane Curing Agent
Product Description
This product is a water-soluble polyisocyanate, solvent-free, non-yellowing, low viscosity, high isocyanate group content, and easily dispersed in water and waterborne polymers. It has a long working life. It can be used as a curing agent (crosslinking agent) for various waterborne adhesives and coatings, increasing temperature resistance, water resistance, solvent resistance, and oil resistance, improving bonding performance, and enhancing the mechanical properties of the film.
Physicochemical Indicators
| ▪ Appearance | ： | Transparent liquid |
| ▪ Solids content (%) | ： | 85±1 |
| ▪ NCO content (%) | ： | 18±1 |
| ▪ Viscosity (mpa.s) | ： | 100-200 |
Application Range
▪ As a two-component waterborne adhesive and coating B-component curing agent or crosslinking agent
▪ Crosslinking agent for waterborne polyurethane emulsion, acrylic homopolymer and copolymer emulsion
▪ Enhancer for synthetic rubber dispersion
Precautions
▪ The general dosage is 3-5% of the waterborne emulsion.
▪ In some special waterborne two-component coatings and adhesive systems, up to 10-20% can be added.
▪ When preparing a small amount of two-component system, hand mixing can be used. When preparing a larger amount of two-component system, it must be slowly added under mechanical stirring, and fully mixed. The working liquid after mixing must be used within 24 hours. It can be applied by hand brush, roller coating, or spraying.
▪ It is very sensitive to moisture and reacts with water to produce carbon dioxide and insoluble polyurea. Therefore, the container must be sealed and stored in a dry room.
Packaging and Transportation
▪ This product is packaged in plastic drums or rust-proof iron drums, with a net weight of 5Kg, 10Kg, and 25Kg.
▪ This product is a waterborne emulsion, non-flammable, non-explosive, and transported as non-dangerous goods.
▪ This product should be stored and transported at 5-35℃, with an effective storage period of six months.
