HROSIN – Honduran Gum Rosin (WG/WW)
HROSIN is colophony or gum derived from varieties of pine trees in Honduras. It is produced by heating fresh liquid resin to vaporize the volatile liquid components. It is semi-transparent and varies in color from dark yellow to light brown.
Main applications include adhesives, chewing gums, coatings, cosmetics, linoleum, paints, printing inks, resins, rubber, sizes, varnishes, and violin rosin.
The main attribute of Honduran rosin is presence of non-saponifiable matter. These are non-acidic waxes that provide unique properties to the Honduran rosin. Some of the unique properties of Honduran rosin are:
- Longer shelf life
- Less brittle
- Less dusty
- Less crystallization
- More transparency
- Slightly more sticky
