Special Properties and Uses

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.

Processing Information

Before application Additol VXL 4950 must be diluted with toluene or xylene, mixing ratio 1 : 8 (Additol VXL 4950 : toluene or xylene). Additol VXL 4950 should be applied in form of a thin coating by spraying process, roller coating or brushing. After a five minutes flash-off time the film can be treated by UV-irradiation or can be overcoated directly with any other paint system. Additol VXL 4950 must be applied as pre-treatment primer and cannot be used as additive in paints.
