Preparation method of Eastman cellulose-Industry News-Guangzhou Xianrenhui Chemical Industry

Eastman CAB can be used as the main film former, resin modifier or additive in coatings. In terms of the selection of the preparation method, the main attention should be paid to the use of the solvent in combination with CAB. In terms of the selection of the formulation method, the main attention should be paid to the combined use of solvent and CAB to ensure the film-forming properties and performance of the coating in different applications.
In a solvent mixture, a good ratio of solvents can greatly reduce the viscosity. The optimal ratio of n-butyl acetate, xylene and isobutanol can make the viscosity reach 2,540CPS; when the ratio becomes 35% n-butyl acetate, 35% xylene and 30% isobutanol, the viscosity increases to About 3 times the original amount. Eastman’s technical support team can help you optimize your formulation.
CAB coating uses a balanced solvent system to provide good performance in construction equipment. For spray coatings, it usually includes an appropriate amount of low-boiling-point reactive solvents to ensure low viscosity of the solution; co-solvents to reduce viscosity and cost; medium-boiling-point reactive solvents and co-solvents to improve leveling; and to reduce costs and provide solutions with modified resins. Hydrocarbon solvents for solubility and compatibility; and slow-drying solvents to prevent blushing.
