Good Wettability Vinyl Chloride And Vinyl Acetate Copolymers Resin
40/43 Used For UV Ink
DR 40/43 is special-modified vinyl resin as exclusive use for
application UV inks and offers
a desirable balance of chemical resistance,excellent ester
soluble,good solubility property
in UV monomer,film-forming,solvent release,paint film strength and
thermoplasticity etc,
which has excellent interbedded adhesion and good bridging
function.

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.
