Honeywell A-C6A wax, as a classic representative of polymeric wax, is widely used in PVC products, masterbatches, rubber products, cosmetics and many other industries. For example, it can be used as an excellent dispersant in masterbatches and has the following characteristics in the production of masterbatches and dispersed pigments:
1. Honeywell A-C6A wax has concentrated effective molecular weight: the molecular weight distribution is narrow and concentrated, which helps to improve the dispersion effect and coloring power. Relatively speaking, under certain dispersion requirements, the amount of addition can be reduced.
2. Honeywell A-C6A wax has excellent heat resistance and thermal stability.
3. Honeywell A-C6A wax has the characteristics of moderate melting point and viscosity match, which helps shear force.
4. Honeywell A-C6A wax has good wettability with various pigments, especially in the formulation of high concentration masterbatches and more difficult to disperse pigments.
Fen Song Coating and Painting Technology
Oxidation, play an anti-deformation effect, the dosage is 0.3% to 1% of the total square, all dispersed by melt extrusion mixing method, the anti-yellowing agent of Hangzhong Chemical Industry and Trade Co., Ltd. can improve the weather resistance of the coating film. Helps to eliminate the yellowing problem of the coating film. The post-quantity is 1% of the total formula, and it is dispersed by the melt extrusion mixing method: the amount of antioxidant is 0.8% of the total formula, 0.5% of the total formula, Giba company outside the township There are also two grades of IRFAN OX and IRG AFOS. The anti-yellowing and chipping 736 is 0.1% in the formulation. product
8. Anti-caking agent (releasing agent or loosening agent)
Qin caking agent (releasing agent or loosening agent) is an auxiliary agent added when the ambient temperature is high, so that the powder coating does not agglomerate during the manufacturing, storage, transportation and use process, and makes it loose or runny. In the summer high temperature season, on the one hand, the environment is high, and on the other hand, the glass transition temperature of the resin in the powder coating composition is low. The effect of the curing agent or other agents makes the powder coating glass transition temperature lower. Wood coatings tend to agglomerate during manufacturing, storage, transportation and use. Among the important reasons why powder wood coatings are prone to agglomeration, the internal reason is the low glass transition temperature of the resin, curing agent and additives selected in the formulation design or polytetrafluoroethylene chain wax chemical The stability is not good; the external reason is that the environmental humidity is higher than 35℃, which accelerates the thermal movement of a certain substance in the powder wood coating, and the forces penetrate each other, and the strength and cohesion are enhanced and agglomerated. Anti-caking is added by adding Agent (Jingzhou Cheng loosening agent) reduces the cohesive force of the powder wood coating particles, or acts as an isolation between the powder wood coating particles, and improves the anti-caking effect of the powder coating.
There are two types of anti-caking agents in the “Loose Agents into Loose Journal”, the internal type and the external type. The C-Plus type is used in the powder coating process and the caking agent is added during the pre-course of the material to melt and squeeze the mountain. Dispersion by mixing method: The external type is to add the anti-caking agent and two types of anti-caking agents after the powder coating is extruded and mixed during the fine pulverization.
