Refined Hydrogenated Rosin


Refined Hydrogenated Rosin is one of the dominant varieties of modified rosin with light color, high oxidation resistance and high thermal stability. It is soluble in ketones, esters, hydrocarbons, alcohols and chlorinated solvents and insoluble in water.
Conjugated unsaturation of abietic resin acids can be removed through catalytic hydrogenation to overcome the shortcomings of oxidation and color degradation in rosin, is compatible in useful proportions with alkyds; natural and synthetic rubbers; natural resins, ethylcellulose; waxes; plastic polymers; elastomeric polymers; metallic pigments; and many other raw materials.

Store

Because of the extremely large surface area, flaked forms of resins are prone to gradual oxidation, some more so than others. This could result in darkening and /or could have an adverse effect on solubility in organic solvents. It is strongly recommended that strict control of inventory be observed at all times, taking care that the oldest material is used first. Recommended storage is in original packaging, dry, free from contamination, below 30°C.

Flaked forms of low to medium-softening point resins may fuse, block, or lump:
(1) during hot-weather months,
(2) if stored near steam pipes or other sources of heat, and
(3) upon prolonged storage and compression.
