Application
It 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 DR-52 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.
Storage
Store in a dry and ventilated place, do not place in open-air, avoid storage in direct sunlight and caution against wet.
Must be transported in clean vehicle with awning and keep away from moisture.
It is NOT hazardous article, and the shelf life is one year from the production date.
