Description of Desired Solution
A leading manufacturer of industrial parts is looking for a technology improving adhesion on polyolefin.
Background
Polyolefins have a low surface energy because they are nonpolar and thus lack functionalities.
To solve adhesion problems on polyolefin, primers are commonly used, but they can have a negative impact on the environment. Other approaches include corona discharge, flame or plasma treatment to create co-functionalities on the surface. But these treatments are costly.
The SpecialChem Client is seeking an efficient cost effective alternative to promote adhesion on polyolefins.
Annual volume purchase for the requested technology has the potential to be in millions of pounds.

Detailed Solution Description
The solution sought by the SpecialChem Client must:
The adhesion will be measured by peal strength which is unique to each application.
The requested technology should also:
- Improve adhesion on the following polyolefins: PE, PP, TPE’s, TPO’s and talc filled variants.
- Have the form of an additive that is compounded into the polyolefin based formulations or that the SpecialChem Client can add at the injection molding press in the form of a masterbatch
- Enables adhesion of these molded polyolefin parts to urethanes and acrylics with consistent performance in the temperature range of -40°C to 80°C
The adhesion will be measured by peal strength which is unique to each application.
The requested technology should also:
- Withstand the high end of the processing temperature range ~440F (227°C)
- Not stick to the injection molding equipment/tooling
- Not volatize VOCs that are of a concern to health or that have an odor
- Shows improvement via measuring the surface tension delta
- Be Lower in cost than flame treating,
Possible Routes To Investigate
Desired solution could be:
- Functionalized Polyolefins modifiers or any functional polymer meeting the requirements
- Cost effective surface treatments
- Cost effective surface treatments
- Additives promoting adhesion (Silanes, Zirconates, Polar resins etc…)
Solution that are not of interest
The SpecialChem Client is not interested in Flame and Plasma treatment nor Corona discharge. Solvent borne primers are also not of interest.
Anticipated Next Steps with Respondents
This is an urgent project for the SpecialChem Client who would adopt a relevant solution as soon as possible.
