Plastics industry: FT waxes can be used in plastics processing such as injection molding, extrusion and pelletizing industries.
Bareco SX-105 polymer can be used in the masterbatch and modified plastics industries to help disperse fillers and provide excellent slip in compounding. 50%, and can significantly improve the product surface gloss. When using thick colors, the melted Bareco SX-105 can effectively wet the dye and reduce the extrusion viscosity.
The extender can be divided into partition extender, oxidized hydrocarbon plasticizer and other types, and ester plasticizer can be divided into phthalate ester, phosphate ester, sebacate and epoxy The advantages of the phthalate scission moisturizer are good compatibility with the resin, obvious plasticizer effect, low volatility, and the common cold property increases with the growth of the alcohol carbon chain, and it has better resistance Yellowing. The advantage of diacid-like vitamin plasticizers is that they have good cold resistance and can be used for plasticizing food contact materials. The plasticizing effect is obvious and the volatilization rate is low. The disadvantage is that the price is relatively expensive. The advantage of phosphate ester bottlers is flame retardant. Good performance. Tricresol phosphate has mildew resistance and good electrical properties; the disadvantage is that it is easier to turn yellow, and has poor light resistance and heat aging properties. The advantages of epoxy ester flashing agents are that the coating film has good heat resistance and light resistance, is not easy to yellow, has good compatibility with resins, has good wetting properties, is non-toxic, and can be used for plasticizing food contact materials ; The disadvantage is that the price is high. The advantage of chlorinated fusion plasticizers is that they have excellent acid resistance, alkali resistance, water resistance and flame retardancy.
The use of plasticizers will improve the hardness and brittleness of powder coatings. Chuan can give the coating some new properties, such as flame retardant, aging resistance, flexibility, impact resistance and elongation. In order to give full play to the plasticizer’s Function, must go through the necessary experiments: choose the appropriate variety and dosage, and different types of plasticizers should be used in combination, which is more conducive to complementary advantages or synergistic effects. Generally, plasticizers are used more in thermoplastic powder coatings, but rarely in thermosetting powder coatings. The addition amount of the formula is 1%~25%. The toughener is added to improve the toughness of the coating film.
Additives and cutting agents also require good chemical stability, do not chemically react with resins, curing agents, pigments, fillers and additives in powder coatings, have good thermal stability, and require good compatibility with resins. After addition, it can significantly change the physical and mechanical properties of the coating film such as flexibility, bending resistance and impact resistance, such as polyvinyl butyral, cellulose acetate butyrate, micronized olefin wax, etc. The addition amount in thermosetting powder coatings is 1%~5% of the total formula, Guangzhou Tianlong Trading Co., Ltd.’s new toughening plasticizer TL815 is a new type of high-flexibility polymer compound, which can improve the flexibility and adhesion of the coating film, and greatly enhance the impact strength. The dosage is 0.5% of the total mud volume. The plasticizer T-81 produced by Shanghai Suoshi Chemical Co., Ltd. is a modified thermoplastic resin that improves the flexibility and bending resistance of the coating film. The dosage is 1%-2%.
