Paints & Coatings

ADDITOL VXL 4950 is a product without special pre-treatment of plastic materials such as polyethylene, polypropylene and polyamide (e.g. corona discharge, roughening, flame or chromic acid treatment) good adhesion of coatings can be obtained after applying a thin adhesion promoting layer of ADDITOL VXL 4950 to the surfaces. For plastic substrates made of polyethylene a short period of additional UV-irradiation of this film is recommendable. In general irradiation of ADDITOL VXL 4950-coatings can further improve adhesion .

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.
