NON-CRYSTALLIZING
GUM ROSIN PR537
Non-crystallizing gum rosins are natural resins modified with formaldehyde to increase resistance to crystallization and oxidation.
They exhibit performance comparable to natural gum rosin, retaining its key solubility and compatibility characteristics while offering superior crystallization resistance and low VOC content.
