The YL-series has a lighter color product line with a maximum Gardner color of 6, with good solubility in various hydrocarbon oil. The SK-series is a standard resin for various applications. The GA-series is a more economic type. They are compatible with ester, ketone, and aromatic and aliphatic hydrocarbon solvents. They can be used as a modifying resin with rosin, phenolic resin, epoxy resin, rubber, vinyl resin, plasticizer or vegetable oil. With low cost, low solution viscosity and high solubility, these low molecular weight hydrocarbon resins can be manufactured into various dispersion vehicles to develop flush color and can also be used as a modifying resin in letdown varnish to improve overall solubility
