Ketone aldehyde resin is a modified products of gum rosin, contains abietic type acids. It has a series of excellent properties such as higher softening point, non-crystalline, good oxidation-resistance, higher viscosity in organic solvent.Ketone aldehyde resin is mainly used in ink, oil paint, rubber, adhesive, waterproof cloth, paper-making, emulsifying agent, etc.
Stored in dry and ventilated condition, be far away from flame.
