Usage: Add it to the front section when mixing.
Dosage: 1 – 3 PHR
1, AC617A is used as processing aid for natural rubber and synthetic rubber, low melting point and low melt viscosity, good compatibility and chemical inertness make AC617A can provide good lubricating performance, so that the product is easier to release, but the vulcanization speed and physical properties of rubber are not affected.
2, AC617A ensures that the rubber does not stick to the rollers during the refining process in the open and closed refining machines. Unlike paraffin and stearic acid, AC617A does not spray frost or ooze and does not cause premature vulcanization (while stearic acid does).
3, It can improve the dispersion of fillers, especially carbon black, during the refining process in the refiner.
4, AC617A can improve the flowability and demoulding performance of rubber, and improve the extrusion performance, also can improve the surface finish of rubber.
5, It is suitable for conveyor belt, hose, gasket, bottle stopper, shoe soles and other industries, applicable to NR, NBR, SBR, IIR, CR, BR, EPDM and other rubber species.
There is also a texturing agent that makes the coating film sand grains through physical action. This sand graining agent is a special vinylidene fluoride polymer modified by acyl rubber. It is a white floc. It is more troublesome to disperse when using a pure substance. It is best to use it first. The colored material is dispersed and used. The principle of this kind of sand texture agent is to increase the melting degree of the powder coating. Moreover, the compatibility between the sand texture agent and the film-forming substance is poor, which changes the surface tension of the molten extrudate and turns the molten extrudate into a spiral.
The horizontal fluidity of the fusion carving is very small, so that the surface is rough and sand-like appearance is formed when the film is formed. This kind of sand texture agent is supplied by Lu’an Jietongdahua 1. Limited Liability Company SA207 texture agent, the dosage is 0.8%~1.5 of the total formula; Guangzhou Tianlong Trading Co., Ltd. AS311, the dosage is the total formula 0.2%~16: ZS007, ZS107 (fine sand pattern), ZS207 of Hangzhou Zhongshun Chemical Industry and Trade Co., Ltd., the dosages are C.1X-0.15% of the total formula 6. Ningbo Nanhai Chemical Co., Ltd. XG618 sanding agent , Is a polyene fried wax modified by tetrafluoroethylene. White flowing powder with a melting point of about 125°C and a particle size greater than 40um. Due to its incompatibility with the base resin, the coating film can produce sand texture effects. Powder coatings produced with this sand texture agent are not easy to be manufactured. The influence of process conditions. The appearance stability of the coating film is good, and the storage stability of the surface powder coating is also good. The appearance and gloss of the coating film of this powder wood coating are affected by the amount of sand texture agent, and at the same time, it is affected by the variety and use of fillers. The quality and dosage of north organic bentonite have a great influence. This kind of sand texture agent is suitable for various resin powder coatings with a wide range of applications.
In addition, the matting sand texture wax AS03/AS05 of Guangzhou Tian Trading Co., Ltd. is a polyvinyl fluoride modified polyethylene film that can also impart matte texture to powder coatings. This matting texture agent is a white powder with a relative degree of about 1.03, a loose density of 285g/L, an python point of about 112℃, and an average particle size of 9jm. The addition amount in the formula is about 0.5% to 1% of the total. If you want to get a sword A coating film with better sand grain and scratch resistance can make Sichuan Perfluoroethylene texture wax AS21, AS22, AS23, etc. The amount of AS21 is 0.1% 0.3% of the total formula, the amount of AS22 is 0.03% to 0.15% of the total formula, and the amount of AS23 is 6.01% of the total formula. In addition, the company’s T1.250 and TL410 sand Texture agents can also be used. The dosage of TL250 is 0.1M~0.3% of the total formula, and the dosage of TL.310 is 1% 3% of the total formula.
