Good Substrate Adhesion Hydroxyl-Modified Vinyl Chloride/Vinyl
Acetate Terpolymers Solbin AL For UV Primer
Vinyl resin VAGD is often used with other film-forming material in
order to improve the coating performance,and enhance paint
adhesion,flexibility,tenacity,hardness and chemical resistance.

Application of Vinyl resin:
VAGD can be used for a wide range of coatings applications,including
marine anti-corrosion paint gravure printing inks,chassis paints,
maintenance, PU and wood finishes, paper coatings, PET inks,
interbedded adhesive, adhesive for magnetic tape and carbon ribbon.
1. Gravure composite plastic ink: provide wetting and dispersion of
various pigments, the ink has bright colors and good printing
adaptability, and can withstand boiling and cooking. Provides
adhesion to PET.
2. Plastic paint: provide adhesion to substrates (ABS, PC, etc.),
good alcohol resistance.
3. UV primer: provide adhesion to the substrate, provide
directional arrangement of silver powder, and provide adhesion to
UV topcoat.
4. Wood paint: provide leveling, provide directional arrangement of
dumb powder, provide solvent release, and have good compatibility
with alkyd and curing agent.
5. Silk screen printing ink: provide excellent color development
performance, and the ink can be made with high solid and low
viscosity.
Solubility of Vinyl resin :
1. Ester solvent solid content is recommended to contain 20%, solvent
recommendation: ethyl acetate, n-propyl acetate, butyl ester, etc.,
the solution is slightly yellow and transparent
2. Ketone solvent solid content is recommended to be 20%-25%, solvent
recommendation: butanone, MIBK, cyclohexanone, etc., the solution
is slightly yellow and transparent
3.Ketone ester benzene mixed solid content is recommended to contain
20%, solvent recommendation: butanone, ethyl ester, toluene, etc.,
the solution is slightly yellow and transparent
Storage of Vinyl resin:
Store in a dry and ventilated place, do not place in open-air,
avoid storage in direct sunlight and caution against wet.
Must be transported in clean vehicle with awning and keep away from
moisture.
The shelf life is one year from the production date.
Package of Vinyl resin:
VAGD have to be packed into kraft bag, lined with pp bags of 25kgs
net, with PE inner bag.
