Partially Hydrogenated Gum Rosin, FLORAREZ PR

Partially hydrogenated gum Rosin has a lighter color and is more stable.

Hydrogenated rosin has more resistance to oxidation and has lighter color.
Like unmodified pine rosin, hydrogenated rosin have a wide span of compatibility with almost all polymers. They are well known for their peel and tack contribution to the adhesive. Specific benefits of hydrogenated rosin include:

Lighter color.
Significantly improved stability.
Less to no skin sensitization (depends on the degree of hydrogenation).
Less UV absorption, thus making them suitable for UV curable polymer based adhesives.
Imparts only a slight decrease of cohesive strength, especially in block co-polymer systems.
Can be used in amorphous polyolefin based adhesives.
CAS Number: 65997-06-0
