High pigment loading without increase in viscosity. Reduction of dispersing time. Enhances gloss and levelling. For air drying and stoving solvent-borne paints and particularly for water dilutable paint systems. ADDITOL XL 203 prevents the floating of titanium dioxide in conjunction with organic or inorganic coloured pigments. It can be employed in solvent-borne and water dilutable air drying and stoving paint systems. ADDITOL XL 203 enhances gloss and levelling of paint films. Pigment loading of paints and pigment pastes can be increased without rises in viscosity. Dispersion time is reduced. The recommended level may range from 0.1 to 1.5 % on total paint. Level on pigments: inorganic pigments: 0.5 - 2.5 %, organic pigments: 1.5 - 5 %. The figures given here may serve as a guide for extensive trials to find the optimum in dosage and effect and to save costs. Since ADDITOL XL 203 is a cationic product it should not be used in conjunction with certain anionic products. Phase seperation occurs and ADDITOL XL 203 becomes ineffective at once. The compatibility should be determined by experiments. ADDITOL XL 203 can be combined with cationic and non-ionic products.

ADDITOL XL 203 is a high pigment loading without increase in viscosity. Reduction of dispersing time. For air drying and stoving solvent-borne paints and for water dilutable paint systems. ADDITOL XL 204 prevents the floating of titanium dioxide in conjunction with organic or inorganic coloured pigments. It can be employed in solvent-borne and water dilutable air drying and stoving paint systems. ADDITOL XL 204 affords higher pigment loading of the paint system and pigment pastes without causing the viscosity rise usual with such products and, at the same time, reduces dispersing time. The recommended level may range from 0.1 to 1.5 % on total paint. Level on pigments: inorganic pigments: 0.5 - 2.5 % organic pigments: 1.5 - 5.0 %, Levels of addition in water dilutable air drying and stoving system may range from 1 to 6 % on pigments. The figures given here may serve as a guide for extensive trials to find the optimum in dosage and effect to save costs.

As a flow- and pumpable paste ADDITOL XL 280 prevents settling and improves wetting of pigments in solvent- and waterborne paints systems. ADDITOL XL 280 improves paint stability. ADDITOL XL 280 is a highly effective additive for all industrial finishes. The easy handling of this material, owing to its favourable rheological properties, saves material and manufacture costs and simplifies the dosage. Difficult dispersible pigments and extenders are more easily and rapidly wetted and stabilized by the action of ADDITOL XL 280. The rheological properties of the coating are favourably affected leading to less tendency to run-off on vertical surfaces and improving edge coverage in dip coating.

ADDITOL XW 395 Enhances surface properties of the films and prevents film defects like insufficient wetting and structured surfaces owing to impurities. ADDITOL XW 395 is an additive specially designed for Resydrol paint systems and, compatibility provided, for other waterborne paint systems. Considering the levels and restrictions given below ADDITOL XW 395 can be used in any water dilutable paint with the exception of electrodeposition paints. ADDITOL XW 395 prevents film defects, such as craters and pin holes or can remedy poor wetting owing to impurities brought into the aqueous paint during preperation or processing. Insufficiently degreased metal is the main cause for such troubles. With ADDITOL XW 395 wetting problems are avoided. It should be noted that film defects arising from silicone oils in many cases cannot be prevented with ADDITOL XW 395. ADDITOL XW 395 prevents floating of pigments, striation, orange peel, etc. and improves the film surface in general. ADDITOL XW 395 at the recommended levels, does not impair the physical properties of the stoved film. In primers ADDITOL XW 395 may cause a certain degree of gloss. Additions of ADDITOL XW 395 may adversely influence the effect of antifoaming agents; on the other hand, it can remedy infavourable effects of the antifoams. In aqueous paints for spray application ADDITOL XW 395 can be used without precautions, while in dipping or flow coating paints ADDITOL XW 395 must be carefully balanced with the antifoams normally present.
