Perfect adhesion on multi-substrates and low polarity surface is possible
The demand for adhesion to several different substrates to be obtained through a versatile formulation is a common request in the market. But it is very difficult to achieve, in particular when non-polar, low energy substrates such as polyolefins and rubbers are used. The need to join these different materials is more and more demanded since the use of plastic parts becomes prevalent in many end applications, such as in automotive for weight saving purpose, and adhesive are replacing 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 mix of substrate wetting and affinity to low polar surfaces, such as plastics.
These performances 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 already contains dimer units.
