Soft Plastic Formulas

Recommended Posts

I am wondering if the formula for plastisol has changed in the last 10+ years.

I pulled out some old Bass Pro floating worms to use as tails on my 2 piece rats, and left them attached for two months in my tackle compartment.

When I pulled them out to tie up for tomorrow, where the worms had been in contact with the rat body the plastic had softened/melted the AC1315 top coat and the Createx paint.

I haven't had that experience, so far, with anything else I've dipped in the AC1315, so I'm wondering if the old worms are a different formulation, or if it's just from leaving them rigged for so long.

Any ideas?

Mark,

 

  Plastics (Plastisol) just always seem to react against other things like paint/urethanes.  I recently made 4 carbon fiber reel handles and have been clear coating to get a ice smooth finish and gloss shine.... my 4 year old came by and put a swimbait I had on the table across them - I found that 1 day later and it had melted the clear coat down to the carbon fiber... not happy to say the least.

 

  I haven't found a rhyme or reason for when baits melt stuff and when they don't..... I'd have an old creme worm laying across the top of my keyboard for months as I'm working on a new bait and been measuring the tail - yet I put a grub I poured there too and it started melting a hole in the keyboard in less than a week???? Go figure.

 

  Maybe put a bit of epoxy over the contact point.... epoxy seems to be pretty "neutral" to things.

All plastic formulations are not the same, they use different products to achieve the same end result. I use to use Mf plastic and if I did not use laminated bags it would react to the one I had over time. Now I use Spikeit plastic and no reaction to the same less expensive bag. It's reaction to certain plastics it come in contact still happens.

I can remember when i was a kid and worms like the manns jelly worm would melt the shelves and or compartments of the tackle boxes, We would wrap our worms in tin foil .then as years went buy they must have started using different plastic to make tackle boxes , it doesn't happen  now to the tackle boxes.

I have an old Pemco tackle box in the garage with holes melted in the plastic trays.  I had forgotten about that.

As far a I know this has all ways been the problem from  day 1   ....  That is with "Hot Melt" Plastisols.  Some have been made with a vinyl that does not have this reaction   ...  Powder Paint and Epoxy are the only solution when touching some thing that will react and this coating can be applied.   ... Certain types of Plastic Boxes from the old days were really bad about this "melting"    ...  Thank goodness they have change some boxes to a formulation that will not react to "Hot Melt"  ...

I put some Zoom trick worms on another batch of rats and they caused no problems.

It's weird.

I have some lead spires heads I poured. I put on some living rubber skirts,bucktail style. I then added some swimbaits made from lurecraft plastic. The skirts turned to a sticky goo, yuck. My cast and store bought baits will melt through hook packaging trays and bobbers too. I had a old tackle box that the trays would melt, but all my newer boxes are fine. I remember when buying tackle boxes in the 80s they used to be advertised as worm proof/resistant.

I'm guessing it's the softener.  An old time local pourer here in SoCal told me I could use it to soften my margarine tub top tails (try saying that three times fast) for my swimbaits, so, evidently, it will soften lots of plastics, not just plastisol.

Couldn't say it worth a darn 3 times, but typed it pretty fast.  Does that count?  LOL

Question of the day.

 

Do you have to be warped to build your own lures?

 

Answer.

 

No, but it sure helps. :D:lol::D
