Uses | Resin for powder coatings; Resin for coil coatings; It is used to synthesize peptic ulcer drugs in medicine. In polyester resin, it is used as a modified monomer; High-solid polyester-melamine drying enamel; Unsaturated polyester resin for gel coating. Application in waterborne polyurethane resin: 1,4-CHDA and AD (adipic acid) have better processability, lower solution viscosity, PIA (phthalic acid) followed by dispersion stability: 1,4-CHDA>PIA>AD 1,4-CHDA can also make the resin achieve a good balance between hardness and flexibility 1,4-CHDA can be used to improve the dispersibility of acrylic resin, and can also have good storage stability. In addition, the coordination line between 1,4-CHDA and acrylic resin is better than that of isophthalic acid (DOP). 1,4-CHDA reactivity is higher than PIA It is used in the synthesis of peptic ulcer drugs in medicine, and in the aspect of polyester resin, it is used as a modified monomer to improve the yellowing of polyester resin, and its flexibility (softness) is improved without changing the hardness. |
