QuadFlex Adhesion Promoter Quart
This listing features one quart of UreChem QuadFlex Adhesion promoting primer & flexing agent. This primer acts as a “tie coat” providing greatly enhanced adhesion to plastics commonly found in the automotive industry. For adhesion to plastics spray one medium wet coat over the surface and allow to flash 30 minutes before applying primer. The product is suppled ready to spray and should not be activated or reduced for use.
This product can also be added to UreChem primers, sealers, and basecoat color to improve flexibility for use over flexible substrates. For enhanced flexibility use up to 20% by volume in ready to spray primers and basecoat for enhanced flexibility on highly flexing substrates. This product is not needed for flex improvement over normal metal and rigid plastic. It is also not needed or recommended for use in UreChem topcoat clears.

grant duvall (Verified Customer) –
I had a chemical reaction with my basecoat that ended up pulling the primer, sealer, and basecoat up from the plastic. i painted my entire truck using only there paints and this only happened on the parts that i used this adhesion promotor on. followed all directions and still ended up screwing up multiple pieces of my paintjob. i painted other pieces of the same material without this adhesion promoter without it pulling. they told me it was from a coating that was on the pieces before i painted. but one was brand new, 2 came from another vehicle and 2 where original. and all had the same issue. and all where scuffed before any paint was applied. wouldn’t recommend taking the chance.
William Purvis (store manager) –
That is a chemical reaction that sometimes happens with any brand of automotive paint and likely related to application and not the product. If it was some how defective Adhesion promoter as suggested it would have failed on the whole area that was primed with the adhesion promoter. Instead it only lifted a few small spots where a primer or base was likely applied to heavy with in-suffecient flash time.

I didn’t observe any difference but time will tell.
