ADDITOL XL 180 enhances intercoat adhesion of stoving paints and fast drying air-drying paints on electrodeposition primers, white electrodeposition paints and primers. ADDITOL XL 180 is dilutable with aliphatic and aromatic hydrocarbons,ketones, esters and alcohols, and is in its form of delivery not dilutable with water. ADDITOL XL 180 improves intercoat adhesion between finish and primer. ADDITOL XL 180 has excellent compatibility characteristics with many binder systems and thus affords universal use. In water dilutable systems ADDITOL XL 180 is best used neutralized with amines, preferably triethylamine. Effects of ADDITOL XL 180 are increased adhesion and enhanced flexibility of stoving alkyd or acrylic resin paints to primers and white paints applied b electrodeposition. In single coats on iron and aluminium, ADDITOL XL 180 does not seem to be efficience. ADDITOL XL 180 as well as its salts can be combined with non-ionic and anionic substances with interfacial activity. Compatibility with cationic substances, however, should be checked individually to prevent mutual flocculation and reduction of gloss. Experience so far has neither shown impaired weathering resistance nor reduced storage stability in connection with the use of ADDITOL XL 180.

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.
