Introduction of Poligen WE6 polyethylene wax emulsion

2021-12-29   Pageview:47

Poligen WE6 is a versatile polyethylene wax emulsion that offers a balanced combination of hardness, breakage and elasticity.

Poligen WE6 is a fine-grained, aqueous polyethylene wax emulsion with high hardness and high melting point; it is produced under high pressure at BASF. Synthesis and production procedures are in accordance with FDA regulations.

Poligen WE6 should not be stored in the open air during the winter months, and care should be taken to prevent ice formation if needed. In case of icing, the solution should be thawed naturally at room temperature, not by direct heating. The reduced dispersion must be filtered before use.

 

 

 

 

 

 

 

polyester resin
Epoxy-polyester powder coating with polyester resin is generally made of polycarboxylic acid,, acid anhydride and polyol condensation and addition surface manufacturing, commonly used polycarboxylic acid and acid anhydride are terephthalic acid, isophthalic acid, phthalic anhydride, adipic acid, azelaic acid, decanoic anhydride, trimellitic anhydride, homophthalic acid, etc.; commonly used polyol are ethylene glycol propylene glycol,, a condensed diethylene glycol (diethylene glycol), neopentyl glycol, 22-methylmalondiol, 1,6-hexanediol, 1,4-cyclohexanedimethanol, glycerol ((propanediol), trihydroxy pentacosanol, etc..
1,6-Hexanediol, 1,4-Cyclohexanedimethanol, glycerol, trihydroxypentacosanol, etc. best synthetic wax The melting and boiling points of representative polycarboxylic acids and polyols are shown in Table 4-84.

When designing polyester resins, the variables are copolymer composition, molecular weight (degree of polymerization), degree of disproportionation (degree of branched chain), functional group type and number, and the combinations among them are infinite. In the design of the actual formulation, a good balance between these factors is obtained according to the requirements of the coating and coating film properties. The relationship between copolymer composition, molecular weight, disproportionation degree and the effect of functional groups on polyester resin, polyester resin properties on powder coatings and coating film properties is shown in Figure 4-7. According to the requirements of powder coating and coating film properties, the properties of polyester resin are considered, and the polyester resin synthesis formula is designed from the properties of polyester resin.
