Can you bond PP, and if so, how?
PP naturally has fairly low surface tension and is therefore difficult to bond. At SABA, we therefore increasingly receive queries from the market on this theme. Our Research & Development team has conducted in-depth research and developed its own primers for bonding PP sandwich panels such as Monopan®, Twintex® and Holypan®.
SABA Primer 4518 is suitable for pre-treatment of bare PP substrates. SABA Primer 9002 was developed for pre-treatment of the coated side of PP materials.
A very large number of PP materials are available in the market. SABA has tested the most common materials, but cannot guarantee that the correct pre-treatment is recommended in this blog for all variants available in the market. We therefore recommend that you always contact SABA for a bonding test with the materials you use.
