| Name | photocuring polyurethane acrylate coating (I) |
| Synonyms | photocuring polyurethane acrylate coating (I) |
| Physical and Chemical Properties | Chemical Properties Polyurethane acrylates prepared from aromatic diisocyanates such as toluene diisocyanate are significantly yellowed after ultraviolet irradiation. Therefore, polyurethane acrylates have recently been synthesized from non-yellowed isocyanate. Its coating is hard and useful as a surface hard coating agent. The viscosity of polyurethane acrylate is very dependent on temperature, mostly high viscosity or solid, and it should be used in conjunction with reactive diluents, so the selection and dosage of diluents are extremely important. |
| Use | Application polyurethane acrylate is a kind of ideal UV-curable resin. UV-curable coatings formulated therewith are widely used as high-grade wood furniture paints, metal, and paper finish varnishes. |
The preparation method of polyurethane acrylate: First, the diol and diisocyanate are reacted to obtain a polyurethane prepolymer with an unterminated isocyanate group, and then the acrylic acid-β-hydroxyethyl ester containing a terminal hydroxyl group is used for the esterification reaction of acrylic acid modification.
