White Powder Carboxyl-Modified Vinyl Chloride/Vinyl Acetate Copolymers Vmch Soluble in Ester
China White Powder Carboxyl-Modified Vinyl Chloride/Vinyl Acetate Copolymers Vmch Soluble in Ester, Find details about China Vmch, Vmch Resin from White Powder Carboxyl-Modified Vinyl Chloride/Vinyl Acetate Copolymers Vmch Soluble in Ester
Grade VMCH: It is white powder, ketone soluble with colorless,transparent solution,and because of the carboxyl functional group,it has excellent adhesion on metal,especially on aluminum foil, the resin foil also has a good adhesion on PVC,ABS,paper,textiles,etc. At the same time, it also has good water resistance, excellent oil, ester, acid, alkali and salt water solution resistance.
Application:
VMCH is used primarily for air-dry finishes, such as maintenance, marine and metal coatings, aluminum foil varnish,cans sealed paint,shoe adhesive,floor paint,cement paint,silk screen printing and transfer ink. And it often mixes with LC-40 grade, which is used in the production of heat sealing packaging coatings, can effectively reduce the heat sealing temperature, raise the heat sealing strength. It also can be used to produce the VC sealing plastic package, Electro-chemical aluminum paint, thermal transfer adhesive.
Package, storage and transportation:
* In craft bag, lined with pp bags of 25kgs net, with PE inner bag.
* Store in a dry and ventilated place, do not place in open-air, avoid storage in direct sunlight and caution against wet.
