2021-12-14   Pageview:385

CLARIANT OP wax is a hard partially saponified montan ester wax with excellent retention of solvent, suitable for the production of various types of flooring, leather shoes, furniture, etc. solvent-based polish with high gloss.

CLARIANT OP wax can be used as a lubricant in plastic molding process, both internal and external lubrication, especially suitable for PVC molding process, can improve the smoothness and gloss of finished products, improve the appearance, also can be used as rubber processing aids, improve the speed of extrusion molding, increase the flow of the mold, easy to release the mold.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Leveling agent is one of the most important additives in powder coatings. In powder coating formulations, when looking for a smooth and smooth coating appearance, whether it is high gloss, gloss, semi gloss, matt or matte powder wood coating, Taiga flow agent is required. The function of the leveling agent is to form a very thin monomolecular layer on the surface of the molten paint when the powder coating modified polyethylene wax is melted and leveled, to provide uniform surface tension, and also to make the powder wood coating and the coated object (workpiece) have good lubrication. Wetness, so as to overcome the effects of pinholes and shrinkage on the surface of the coating film due to uneven local surface tension. In addition, the leveling agent is beneficial to improve the leveling of the coating film and reduce the orange lines of the coating film. Facilitate the dispersion of pigments and fillers, and the degassing during the film forming process of Ding

Commonly used leveling agents in powder coatings include acrylic ketone homopolymers, acrylate copolymers, silicone modified acrylate polymers and polysiloxanes, among which polyethyl acrylate, polybutyl acrylate, Polylactone-2-ethylhexyl hexyl ester, copolymer of ethyl acrylate and butyl acrylate and silicone modified acrylate polymer and other high molecular compounds. There are also hydroxyl and carboxyl groups in the acrylate copolymer leveling agent. A compound copolymerized with a group of monomers, this leveling agent with a polar group, due to the role of the polar reactive group, is conducive to the dispersion of pigments and fillers, is conducive to improving the gloss of the coating film, and acts as a composite additive The role of. The structural formulas of acrylate homopolymer and acrylate copolymer are as follows:

Acrylate homopolymer: LCH, CHw, R-CaCa alkyl CO OR R
Acrylate copolymer: CH: -CH JF CH, CH.R-H or CHs, Re, Ra-Ce~Ca burn group CO OR: CO OR:
Acrylate copolymers containing reactive groups:
Ecl: -CHl FCH, Clf Ryle Rel,, R-H or CHi; Ri, Rz = Alkyl of Can Cu; R contains OH group CO OR: CO OR:
Monomer; Re=monomer containing COOH group

The leveling agent for powder coatings is generally a viscous liquid. In order to make the viscous liquid leveling agent convenient in the production of powder coatings, it is usually dispersed in epoxy resin, high acid value polyester resin (epoxy polyester Powder coatings), low acid value polyester resins (polyester powder coatings), fumed silica or some fillers, formulated into solid particles or powder for use. Usually dispersed in molten epoxy resin called 503 leveling agent; dispersed in molten high acid value polyester resin called 504 leveling agent; dispersed in molten low acid value polyester resin called 505 leveling agent: dispersion In the fumed silica is called a general-purpose leveling agent.
