Our Primer P400 from Weicon is a high quality, industrial-grade adhesive primer used around the world. It is designed to facilitate the bonding of otherwise hard to bond materials with low surface energy. This primer activates the surface which allows you to create a good, strong, lasting bond and/or seal.

Available in 250ml cans, it has a fast evaporation time (aka reaction time). This means you need only wait a minimum or 10 minutes before applying the adhesive. The adhesive should be applied no later than 1 hour after you have applied the P400 Primer.
