1, HY-8266 improves the adhesion of paint film to various hard-to-adhere metals such as aluminum, zinc, stainless steel, plating surface,
2, HY-8266 increases the ductility and impact resistance of the paint film.












At present, the commonly used wrinkle (orange lines) agents in China are cellulose acetate butyrate CAB-551-0.01, CAB-551-0.2 and CAB-531-1 for powder coatings of Eastman wax emulsion surfactant Company of the United States, etc., and Guangzhou Tianlong Chemical Co., Ltd. Wrinkle agent AS01, AS10, AS330, special effect wrinkle agent AS3B, wrinkle agent HOT-805 of Hubei Hongtu Chemical Products Co., Ltd., wrinkle agent MCB of Wuhan Yanhuang Chemical Co., Ltd., etc. These wrinkle (orange lines) agents are all in Add it as ingredients. The following specifically introduces the properties and uses of various wrinkle (orange lines) agents.

Cellulose acetate butyrate (CAB) is a commonly used polymer compound additive in coatings. In solvent-based coatings, it is used to improve film leveling, reduce shrinkage, and improve abrasion resistance, UV stability and yellowing resistance. , Aluminum powder is oriented and used for purposes such as improving solvent resolubility resistance. There are many varieties of cellulose acetate butyrate, among which the commonly used varieties in powder coatings are the above-mentioned CAB-551-0.01, CAB-551-0.2 and CAB-531-1.

The dosage of cellulose acetate butyrate in the powder coating formulation is 0.1%~0,3% of the total formula. As the dosage increases, the three-dimensional appearance of the orange pattern of the coating film decreases and gradually becomes a smooth appearance. When the dosage is increased again When it is above 0.5%, the appearance of the coating film becomes completely flat: with the decrease of the dosage, the orange pattern of the coating film becomes stronger. When it is reduced to a certain degree, the coating film is easy to show the bottom, so choose according to the appearance requirements of the coating film. The variety and dosage of cellulose acid butyrate are necessary. In addition, the type of filler and the volume concentration or mass fraction of the filler in the formula have a certain effect on the appearance of the orange texture. The gloss of the coating film can be obtained with different gloss by the general method of powder coating matting. The cellulose acetate butyrate additive is suitable for various powder coatings.

AS01, AS10, AS330 and AS3B wrinkle agents are products of Guangzhou Tianlong Chemical Co., Ltd.
