AK47 Posted December 12, 2017 Report Share Posted December 12, 2017 Hi all! I have tried to make my own homemade plastisol. I mixed DINP plasticizer (approx. 80%) with emulsion PVC paste resin (approx. 20%), also add metallic thermostabilizer and epoxy soybean oil as an additional thermostabilizer. Everything is Ok, except that my lures has sticky/ tacky feel. Could somebody advice me, what else I need to add to avoid this sticky/tacky feel? Thank you in advance!

Baitjunkys Posted December 12, 2017 Report Share Posted December 12, 2017 Soybean oil replaces dinp as a plasticizer, you probably have way to much plasticizer. 1 Quote Link to comment Share on other sites More sharing options...

I added just a few % (approx. 2% or 3%) of epoxy soybean oil. As I found on chemical forums, ESO can partially replaces dinp as a plasticizer, but mainly uses in small amount as an additional thermostabilizer.

Baitjunkys Posted December 12, 2017 Report Share Posted December 12, 2017 if you are using paste, back off on the plasticizer. To much makes it sticky. 1 Quote Link to comment Share on other sites More sharing options...

But I use PVC paste resin, actually it's not a paste, it's a grade of PVC resin, which can be used to make a paste (should be mixed with plasticizer to get a paste or plastisol). Quote from the website of this resin manufacturer: "Emulsion paste-forming polyvinyl chloride with non-alkaline pre-stabilization. White solid material, odorless. It is suitable for production of pastes of medium viscosity, little pseudoplastics pasts." Quote Link to comment Share on other sites More sharing options...
Anglinarcher Posted December 12, 2017 Report Share Posted December 12, 2017 Baitjunky's is a maker of the stuff. I would tend to take his word for it. 1 Quote Link to comment Share on other sites More sharing options...

I have no doubt in his qualification. And I'm grateful to him for his attention to my question. Also I would like to clarify - I live on another continent, so I'm not planning to be a competitor for your plastisol manufacturers. At least, this year Quote Link to comment Share on other sites More sharing options...

I haven't a durometer, but approximately - similar with brands lures, for example - Lunker city, Zoom etc. Quote Link to comment Share on other sites More sharing options...
Baitjunkys Posted December 12, 2017 Report Share Posted December 12, 2017 Cut back on your plastizizer or add more resin. You are likely to soft and the resin is not absorbing all the plasticizer, hence sticky. 2 Quote Link to comment Share on other sites More sharing options...

I have tried to increase the weight of resin to 30% - the stickiness of the lures decreased (but not completely disappeared!), but the softness was unsatisfactory.

I have tried to increase the weight of resin to 30% - the stickiness of the lures decreased (but not completely disappeared!), but the softness was unsatisfactory. I believe you need a dispersing agent in the formula, I believe it is possible that the plasticizer is not spreading throughout the formula hence some, but not total stickiness. But it can also be the chemicals in the resin that breaks apart when not mixed correctly that is causing over stickiness, so it could also be how the resin was made.

Baitjunkys Posted February 23, 2018 Report Share Posted February 23, 2018 Plastisol is sticky by nature, It is covered up with mineral seal oil or other like materials that exude after it is heated etc. Best thing, run with what you got, wipe them in mineral oil when you take them out of the mold, Unless of course there so sticky there sticking to the mold itself. 1 Quote Link to comment Share on other sites More sharing options...
Guest DiyEngineer Posted February 23, 2018 Report Share Posted February 23, 2018 (edited) Baitjunkys , I am quite aware of that but when certain chemicals in the pvc resin can add lot or a little stickiness which is variable on the company that produces it or how it was made.. Also some formulas of plastisol contain tiny droplets of lubrication (oils or glazes) that are released when it cools removing the stickiness temporarily or permanently. I know some on plastisols, but far more on organics or bioplastics. Edited February 23, 2018 by DiyEngineer typo Quote Link to comment Share on other sites More sharing options...

Leon Nolte Posted July 5, 2022 Report Share Posted July 5, 2022 I am also in formulating pvc plastisol for marlin skirt lures. Have to make it much harder than the soft bait Plastics. Two ways I will use is dip molding and injection molding like in soft baits. Gellation takes place at 170c and liquidise at about 280c . What will the problem be for this high heat requirement Quote Link to comment Share on other sites More sharing options...
