DBB Gum Copal

DBB Gum Copal

DBB grade is pebble sized and whitish yellow in color with about 90-95% purity. This is an economy grade, ideal for production of low-end varnishes. Its solubility is good. It can contain some black copal but it is still easily dissolved in alcohol solvent mixtures. It is also the most common grade for use in incense.
