Modified Rosin
Disproportionated Rosin, DPR can be used as rubber plasticizer, adhesive tackifier, pigment wetting agents and dispersants.
Application and Recommendation
1. Disproportionated Rosin, DPR
Recommendation: KMDS, KMDM
The major composition of disproportionated rosin (DPR) is dehydroabietic acid. The lowered abietic acid content of DPR enhances its stability. DPR can be made into disproportionated rosin acid potassium soap that can be used as an emulsifier for polymerization of styrene-butadiene rubber, neoprene rubber, nitrile rubber, and ABS. It can be used as rubber plasticizer, adhesive tackifier, pigment wetting agents and dispersants.
2. Water-White Hydrogenated Rosin
Recommendation: KHR70E, KHR70EX, KHR70S, KHR75, KHR130
The major composition of hydrogenated rosin is dihydroabietic acid or tetrahydroabietic acid. It features water-white color, anti-oxidizing ability, anti-crystallization, and stability. Hydrogenated rosin is mainly used in electronic solder flux, solder paste, high-performance adhesives, high-end coatings and inks.
3. Modified Gum Rosin
Recommendation: 140, 278L, K107, KR130, H110, H120
The modified rosins are obtained through modification. They feature a wide range of softening point, acid value, and color. They are good alternatives to serve the requirements of our customers. Recommended use: water-based or alcohol-soluble adhesives, coatings.
