FAQ
GR-70 eliminates styrene monomer residuals and avoids long-term yellowing in white and pastel shade systems. It meets eco-label restrictions (e.g., EU Ecolabel for indoor paints) that prohibit styrene-containing binders. Performance in carbon black and organic pigment dispersions is equivalent to GR-50 with slightly better exterior UV durability.
