Application:
VAMA 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. VAMA often mixes with LC-40, 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.
