Perfect adhesion on multi-substrates and low polarity surface is possible
The demand for adhesion to several different substrates is a common request in the market. However it is very difficult to achieve, particularly when non-polar, low energy substrates such as polyolefins and rubbers are used. The need to bond these different materials is increasingly demanded since the use of plastic parts has become more prevalent in many end applications, such as in automotive for weight saving purpose. Adhesive are also increasingly used to replace welding and mechanical joints.
You can overcome these challenges by using the Croda dimer technology.

Pripol dimer structure
The branched structure, and the hydrocarbon character, impart the unique combination of features of substrate wetting and affinity to low polar surfaces, such as plastics.
These characteristics can be obtained using Pripol dimer diacid, Pripol dimer diols and Priamine dimer diamine in a variety of polymers, such as polyesters, polyamides, epoxies.
For polyurethane based products, we have developed our Priplast polyester polyol range which contains dimer units.
