ADDITOL VXL 4930 may be used in all solvent-containing and water-dilutable paint systems. It promotes the spray dust absorption, prevents orange peel and increases scratch resistance. ADDITOL VXL 4930 is effective at low concentrations and at the correct dosage, does not adversely affect intercoat adhesion. Blistering, cratering and floating in pigment blends are effectively prevented. It does not stabilize the foam during paint production and application. The substrate wetting is advanced.ADDITOL VXL 4930 is used primarily in industrial stoving/baking paints and 2K PUR paint systems.

ADDITOL XL 109 prevents surface defects in oxidatively drying paints, like icing, wrinkling, shrinkage. Enhances through-drying, levelling and hardness. For paints on oil and alkyd resins. ADDITOL XL 109 is a specific antioxidizing agent for oxidizing paint systems and inhibits or retards the crosslinking reactions initiated by air oxygen in the surface of paint films. Thus ADDITOL XL 109 acts as antiskinning agent and impairs too quick drying of the surface. The paint films remain liquid for longer times and oxygen can contact the deeper layers of the films. Through drying is enhanced and becomes uniform over the whole layer of the film.Surface defects usually due to inuniform drying, like icing, wrinkling and shrinkage can be prevented. At the same time, gloss, levelling, and film hardness are enhanced.ADDITOL XL 109 remains active in the paint on prolonged storage in closed containers. Crystallization eventually occurring on storage at lower temperatures can be dissolved by gentle heating. We recommend to jointly use ADDITOL XL 109 and ADDITOL XL 297. Both additives are supplementary in effect giving superior performance in respect of antiskinning, drying and gloss.

ADDITOL VXW 6206 is the leadfree and bariumfree combination drier. ADDITOL VXW 6206 produces in waterborne alkyd resin paints a good set-drying combined with an even through-drying. ADDITOL VXW 6206 contains a balanced metal combination which is for an optimum oxidative drying necessary.ADDITOL VXW 6206 may be added as siccative to all waterborne oxidatively drying alkyd resin paints. Especially suitable for externally emulsified alkyd resin emulsions.

ADDITOL VXW 6235 gives rapid foam retardant results, which remains effective during storage of the aqueous powder coating. The flow property of the coating is not effected. Pin hole free films are obtained. ADDITOL VXW 6235 it is mainly recommended for powder coating materials to be used in aqueous systems eg: Emulsion paints, 2-component epoxy systems, Plasterwork, Filling compounds and scalants, Flooring compounds, Adhesives and Good effects are also seen in liquid non glossy water reducible coating systems.
