ADDITOL XL 121 is a paint additive to enhance mar resistance and levelling of air drying and stoving paints, particularly for silicone modified air drying and stoving alkyd resins. ADDITOL XL 121 is a silicone containing paint additive supplied as low-viscous solution. ADDITOL XL 121 enhances mar resistance of solvent-borne paints by reducing the surface resistance of the paint film. ADDITOL XL 121 improves levelling and prevents film structures and thus enhances film performance in general. ADDITOL XL 121 is suited for air drying alkyds, stoving alkyds, thermosetting acrylic resins, nitrocellulose paints, acid curing paints, alkyd-acrylate-isocyanate systems, and particularly for air drying and stoving-silicone modified alkyd resins. The effect of ADDITOL XL 121 depends on the type of paint system and on the formulation. The quantity of ADDITOL XL 121 may range from 0.1 - 0.5 % on paint as a guide.

HYDROXYPROPYLCELLULOSE H is an additive soluble in water, water-free lower alcohols and polar solvents. Solubility in organic solvents is limited only by the viscosity increase. Viscosity of HPC in aqueous solution is virtually unchanged in pH range from 1-12.
