[1] The resin is 50% (mass fraction) solution in butyl acetate and
ethanol, they account for 85% and 15% respectively.
Application
Dissolved into solvents to prepare 50-70% resin liquid, then added
it into coatings/oil ink formulas. Generally adding percentage
is 5-30% of the formula’s total mass.
Solubility
Soluble in almost paint solvents such as aromatic hydrocarbons,
alcohols, ketones, esters etc. But insoluble in water.
Its solubility in non-polar solvent such as mineral oil, aliphatic
hydrocarbon, alicyclic hydrocarbon is limited.
Storage
Ketonic resin should be stored in cool & dry warehouse.Prevent
from sunshine & moisture.
Avoid high temperature . Avoid rain during
transportation. It is not dangerous cargo.
Package
Packed into 25kgs/bag with pallet
