PINECRYSTAL

A rosin derivative developed with Arakawa Chemical's proprietary technology, characterized by its light color and low odor.

It is suitable as a tackifier for UV-curable acrylic adhesives due to its superior weather resistance and low absorption of UV light compared to general rosin derivatives.

Its hypoallergenic properties also make it suitable for use in adhesives that are supposed to be in contact with the skin.
