Hydro Solutions vs Aqualac Adhesion Testing (Pic Heavy)

Hey guys, wanted to throw this up here for everyone. Before I go further, this was done for my own personal benefit. If Adhesion was better w/ HydroSolutions, it would save me quite a bit of time and money. So this was my parts using my process. We normally use Aqualac and LOVE it. It works very well for our process and the price is very good in bulk. Here we go.

Parts used were 4 firearm shrouds (E-Coated Metal) and 4 forearm covers (polypropylene). All parts were degreased in our heated degreaser/parts washer as our normal process. Normal process are to lightly sandblast the shrouds to etch the e-coat and get a mechanical bond. The polypropylene parts get a NanoChem adhesion promoter sprayed and then the Aqualac paint. Here's a breakdown of the test (the HydroSolutions paint is a bit darker colored).



Shrouds
Part Desription
1A Sandblasted (Aqualac)
2L Sandblasted (Hydro Solutions)
3A Not Sandblasted (Aqualac)
4L Not Sandblasted (Hydro Solutions)***

Forearm Covers
Part Description
1A Adhesion Promoter (Aqualac)
2L Adhesion Promoter (HydroSolutions)
3A No Adhesion Promoter (Aqualac)
4L No Adhesion Promoter (Hydro Solutions)***

***These are what I'm testing that will improve my process.

I expected parts 1A and 2L to pass and part 3A to fail on both the Shrouds and Forearm covers. Parts 4L were the unknown.

When painting the Hydro Solutions paint I used an Iwata LPH400LVX w/ a 1.5 tip to spray (same as we use w/ Aqualac). The paint acted identical to Aqualac, which is awesome. Exactly what I wanted. It layed down super smooth, covered a black part easily with one coat, and was not noticeably different from Aqualac in any way. Even smelled the same. LOL. Here's a side by side photo of the shrouds.



Now for the adhesion. The first cross hatch across the top of the parts was clear packing tape. I then used some very sticky masking tape (which felt stronger than the clear packing tape) on the bottom cross hatches of the shrouds and on the sides of the forearms. If we are ever unsure if a rack of parts has had Adhesion promoter? We stick some of that masking tape on the ridges and pull. If it looks like the right side of the 3A forearm? It was missed.





My testing showed there is no difference between them when applied to the polypropylene parts, and nearly identical results on the e-coated metal, with slight advantage to Aqualac (but both still failed, so I call this a tie also). The HydroSolutions passed all the test with flying colors using our normal prep process. Since all my testing came back equal, if they can get the price lower than Aqualac? I would absolutely make the switch.

    Thanks Joe. The 3A and 4L shrouds do not look the same to me. So can we say it holds to polypropylene as well as Aqua Lac and not so well to E-coat? Not that I would use it direct to any metal but you pulled the whole enchilada off and Aqua-lac still has some grip. You have saved me a lot of time thanks again young man.

    That all depends where you get it. I'm pricing 55 gallon drums and priced at a fraction of that. But in gallon quantities? Absolutely better to go w the $68 price.

    Another (non sponsor) supplier has relabeled Aqualac black for $60.65/gallon.

    And yes @Tsunami the Aqualac did hang to the e-coat better. But still a fail. That's why I said slight advantage to Aqualac on e-coat.

    Actually, on a side note, the polypropylene primer from Prime Coatings does very well on e-coat, and the Aqualac hangs even better. But the problem arises after the dip. When the activator softens the paint the adhesion goes to hell. The paint will roll right off the shroud, even by blowing w compressed air. If you leave them to dry overnight? The adhesion is fine again. Just not very conducive to our production schedule.

    Activator changes everything...I think I heard that somewhere...
