Excellent adhesion without sanding on parts. Two-component, highly filling primer. Suitable for all paint systems. It cross-links excellently with Hardener For Primers H 729 Normal and H 725 in a 4:1 ratio and is compatible with all paint systems. Attention: If you use the accelerator A715 TURBO AX in combination with primer P307, be aware that the pot life of the ready-to-apply mixture is significantly reduced. For this reason, the product should be applied as soon as possible.
