Paint System for Polypropylene

Specialist paint manufacturer Dr A Schoch AG has recently launched new paint systems into mainland Europe and the UK, which can adhere to polypropylene (PP) substrates without the need for pre-coats, abrasive blasting or plasma treatments.

Using the new paint systems, a polypropylene substrate only requires normal cleaning with isopropanol. It can then be painted directly with up to three coats, depending on individual technical requirements.

Three basic systems are currently offered – polypropylene primers with direct adhesion to be over coated by base coats and clearcoats or topcoats, polypropylene basecoats with direct adhesion to be over coated by clear coats or topcoats, and polypropylene topcoats with direct adhesion for interior or exterior use as glossy or matt finishes.

The systems are suitable for internal or external coating applications, and have been thoroughly tested for UV stability and corrosion resistance.

Mark Robinson, Dr Schoch’s recently-appointed UK Technical/Sales Manager says, ‘We consider this a major breakthrough in the technology of painting on plastics. Painters and moulders will now be able to paint polypropylene as they would most other substrates.’
