Excellent Flexibility Vinyl Chloride And Vinyl Acetate Copolymers
Resin 40/43 Used For UV Coating
In UV system, DR 40/43 can provide good dispersibility in
pigment,improve the flexibility
and plumpness of paint film and adhesive force of material base,
lessen the procedure of
base coating, and it can reach VOC zero release and conform to the
requirements of environmental protection.

Application
1. UV varnish: solution colorless transparent, high gloss of paint
film.
2. UV ink: the pigment has a good wettability, improve the pigment
development.
3. UV coating: provides adhesion to the substrate (PVC, PU, paper,
PC, etc.), provides
excellent flexibility and high bending resistance.
4. PTP aluminum foil heat sealing adhesive: it is used in
combination with carboxyl vinyl resin
to greatly reduce heat sealing temperature (150℃ to 140℃) and
improve heat sealing strength
on aluminum and PVC heat sealing.
5. All-in-one machine paper adhesive: improve the adhesion fastness
to the paper.
6. Hot stamping coating: reduce the stamping temperature and
provide adhesion to the substrate.
7. Carbon belt: reduce melting temperature and provide adhesion.
Solubility:
1 . In the UV system, it can be well dissolved in HDDA, TMPTA or
cationic monomers to make
a resin solution of 10-40% solids, and can also dissolve part of
solvents and part of monomers
to achieve a higher Solid, colorless and transparent solution.
2 . The solid content of the ester solvent is recommended to be 20%
-25%, the solvent is
recommended: EA,NPAC, NBAC, etc., the solution is colorless and
transparent.
3 . The solid content of ketone solvent is recommended to be 20%
-30%, the solvent is
recommended: MEK, MIBK, CYC, etc., the solution is colorless and
transparent.
