2021-12-22   Pageview:253

Customer segment: PA66 glass reinforced modification

Industry Problem: Automotive water tanks are particularly important for hydrolysis resistance and high temperature resistance due to the high temperature environment of hot water and glycol.

Solution: 691 has a heat loss of only 0.6% at 300 degrees, and very good hydrolysis resistance, very low additions, no precipitation, and excellent cost.

 

 

 

 

 

 

 

 

 

 

 

 

 

Cellulose acetate butyrate and cellulose acetate propionate powder coatings
Cellulose acetate butyrate and cellulose acetate propionate powder coatings are thermoplastic powder coatings composed of cellulose acetate butyrate resin or cellulose acetate propionate resin, pigments, fillers and additives. Cellulose acetate butyrate and cellulose acetate propionate are well known for color matching, toughness, water resistance, solvent resistance and durability. They were first used to formulate spray paint or for injection molding, and later in powder coatings. Aspect is applied. Cellulose acetate butyrate and cellulose acetate propionate powder coatings can be applied by fluidized bed dip coating and electrostatic powder spraying. In order to ensure the adhesion of the coating film to the substrate, a primer must be applied first. This kind of powder coating is used for thin coating. Generally, electrostatic powder spraying is carried out after the primer is applied, and it can be melted and leveled after baking at 230°C for about 8-10 minutes. The cellulose acetate propionate powder coating complies with the US Food and Drug Administration (FDA) standards and can pe wax in vietnam be used on food-related products, such as the shelves in refrigerators. The technical indexes and film properties of cellulose acetate butyrate and cellulose propionate powder coatings are shown in Table 3-33. Because the coating film has better weather resistance, it can also be used outdoors.

Thermoplastic polyester powder coating is a thermoplastic powder coating composed of thermoplastic polyester resin, pigments, fillers and additives. It is generally manufactured by pre-mixing of raw materials, melt-extrusion mixing, cooling, pulverization and screening and classification. Polyester resin is synthesized by condensation reaction of various dicarboxylic acids and glycols. This powder coating can be applied by fluidized bed dip coating or electrostatic powder spraying.

Because the coating film has good adhesion to the substrate, it is not necessary to apply a primer first. Thermoplastic polyester powder coatings have high resin molecular weight, high softening point, and high corresponding glass transition temperature. The storage stability of powder coatings is very good. The physical and mechanical properties and chemical resistance of the coating film are also relatively good. Representative Resin technical indicators and corresponding powder coating film properties are shown in Table 3-34. This powder coating is mainly used for the coating of transformer shells, storage tanks, road safety fences, shelves, household appliances and their parts. The disadvantage of this powder coating is the poor heat and solvent resistance of the coating film. There is no report on the application in our country.
