Vinyl Chloride and Vinyl Acetate Copolymers Resins TLC-40/43
Vinyl Chloride and Vinyl Acetate Copolymers
New Grade TLC40/43: It 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.In UV system, it 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; Vinyl Chloride and Vinyl Acetate Copolymers Resins also has well sealing property in low temperature due to its lower melt index.
Vinyl Chloride and Vinyl Acetate Copolymers can be best soluble in HDDA,TMPTA etc monomer in UV system with resin solution 10-20% solid content, and it can also be dissolved in part of solvent and part of monomer to get higher solid content.

Application:
TLC40/43 new grade is mainly used for UV gloss oil,UV inks,UV coatings,gravure composite printing inks(ketone and ester soluble etc solvent base),ECO inkjet inks,all-in-one machine paper adhesive, When using with carboxyl resin in the heat sealing lacquer for aluminum foil and PVC can effectively reduce the heat sealing temperature, raise the heat sealing strength
