Waterborne polyurethane resin is a type of polyurethane resin that uses water as a solvent and dispersed phase. Compared with traditional organic solvent based polyurethane resins, water-based polyurethane resins have advantages such as low volatility, no odor, and environmental protection. Due to its environmental friendliness and excellent performance, waterborne polyurethane resin is increasingly valued and widely used in the market.
Nature:
1. Waterborne polyurethane resin has good rheological properties and is easy to apply and process.
2. Has excellent water resistance and chemical resistance.
3. Has excellent adhesion and wear resistance.
4. It can be dried and cured at room temperature without the need for additional baking.
5. Non toxic and odorless, meeting environmental requirements.
Usage:
1. Waterborne polyurethane resin is widely used in the field of coatings, such as wood coatings, metal coatings, plastic coatings, etc.
2. It can also be used in fields such as adhesives, inks, textile coatings, etc.
3. Suitable for interior decoration, furniture, automotive fields, etc.
Method:
The preparation of waterborne polyurethane resin first requires the preparation of raw materials such as polyether, polyester or polyether ester polyols, isophorone diisocyanate, etc.
Polyurethane resin is prepared by reacting raw materials in a certain proportion, and then dissolved and dispersed in water to obtain waterborne polyurethane resin.
Security information:
1. Waterborne polyurethane resin has better safety compared to organic solvent based polyurethane resin, with no volatile organic solvents and reduced impact on the environment and human body.
2. During production and use, attention should be paid to avoiding direct contact with skin and eyes, and appropriate protective equipment should be worn if necessary.
