Vinyl Resin,HA

HA Type Vinyl Chloride-Vinyl Acetates Copolymer

Main Application

HA Type resin can be used in corrosion resistance coatings for industrial pipe, steel structure,machine tool and shipping vessels. It features weather resistance, abrasion resistance and salty mist resistance.

HA Type Resin can form film by solvent evaporation. Same as all other Vinyl Chloride-Vinyl Acetates Copolymer, it features good toughness, durable flexibility,
wearing resistance, waterproof,excellent oil grease, diluted acid, alkali and salt solution resistance.

It can resist to hydrocarbon and alcohols like petroleum solvent.


Ketone is very good solvent for chloro-acetie copolymer, such as acetone, methyl ethyl ketone, cyclohexanone and isophorone. This product belongs to high content of Vinyl Acetates and low polymerization degree Copolymer. Therefore, xylene and butyl acetates mixing solvent with 10% of methyl ethyl ketone can disolve this product to form 30% high solid content solution. The product even can be disolved in the solvent without ketone.


HA type resin can be compatible with other chloro-acetic copolymer resin, PVC
resin, perchlorovinyl resin, poly-ketone resin, chloroprene rubber, nitrile rubber, polyacrylates, epoxy resin, polyester and petroleum resin. It also can compatible with low viscosity, ester-soluble nitrocellulose, alkyd resin.


Pigment and Filler:

Most Pigment and Filler can be used, such as Titanium Dioxide, chrome oxide green, carbon black, chrome yellow, barite, mica powder, calcium carbonate, etc. But when zinc, cadmium and iron oxide pigments are applied, special care should be taken, because it has catalysis function to the decomposition of chloro-acetic copolymer at high temperature.

HA type resin has good light resistance and heat stability, but when it is used in outdoor at high temperature, organotin without sulfur composition and epoxy compounds stabilizer need to be used. UV stabilizer with light resistance can be added.

This product has excellent solubility, therefore, it can formulate inks for shrinkage film of PVC, act as binding resin to replace 50% of acrylic resin in inks.


Adding certain amount of HA resin in PU adhesives can increase initial adhesion and permanent adhesion abilities, also can increase the adhesion strength for PVC and EVA materials.

Food Products Regulation:
UM type resin complies with Chinese Food Packaging Application PVC Resin Sanitary Standard, Code No. GB4803.

Hazardous Chemical Regulation:
HA type resin is not Hazardous and Toxic Chemical and does not have classification number in “Hazardous and Toxic Chemical Category Number”  Code: GB6944-1986 issued by People’s Republic of China.

Packaging and Storage:
25 Kg/Bag.   Two options for the packaging bag: Craft Paper Bag or PP Knitted Bag lined with plastic film.
Stored at dry place at room temperature.
