Property

VAMA has excellent adhesion on metal, especially on aluminum foil, the resin foil also has a good adhesion on PVC , ABS, paper, textiles, beton, etc. At the same time, VAM has good water resistance, excellent oil, ester, acid, alkali and salt water solution resistance.
dissolved in relatively strong solvent/diluent combinations, such as ketone/aromatic diluent (50/50 percent by weight), to produce solutions of 22 to 25 percent solids. Ketones is a particularly good solvent, and esters is the relatively weak solvent

Application

Used for maintenance, marine and metal coatings, aluminum foil varnish, cans sealed paint, shoe adhesive, floor paint, cement paint, silk screen printing and transfer ink, heat sealing packaging coating, Electro-chemical aluminum paint, thermal transfer adhesive.
