Solubility
Ketonic resin 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.
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.
Package
Packed into 25kgs per bag
