Colorless rosin derivatives [PINECRYSTAL]

World's first colorless rosin derivatives

Colorless rosin derivatives [PINECRYSTAL]

Our own technologies allowed us to achieve a world's first invention of a natural resin, rosin, with an ultra-light-coloring. It is a derivative of rosin featuring a more stable color and quality, and is used as a material of tackifiers and soldering flux.

We found that some rosin compounds can solidify oil. Based on this, we developed a rosin-based oil solidifying agent that works at room temperature.
