Guest DiyEngineer Posted March 27, 2018 Report Share Posted March 27, 2018 This formula was designed to be extra heavy for far casting or deep water fishing, without the use of salt or glass(I will do some with these in the future), It uses tungsten-iron-silica powder (aka black sand), i would recommend this recipe for anyone with a ball mill( as the powder must be fine). When handling this material please wear a face mask, goggles, and remove any nearby magnets. Please work out side if possible, when it is not windy. Formula 3DH or 3-third D-Durable H-Heavy. Keep in mind that this formula is theoretical, reason is I don't know what you may be working with as far as equipment. Percentage of Materials -67% DINP Plastecizer -15% Emulsion PVC Paste Resin -2% Soybean oil or Mineral oil (90% pure mineral oil) -3% Tin Thermal Stabaliser (Tetramethyltin) -5% Dispersent (website on dispersents https://www.byk.com/en/additives/applications/plastics-industry/pvc-plastisols.php I do not work for any of the companies mentioned in this website) -8% Black Sand .1 microns to .75 microns Quote Link to comment Share on other sites More sharing options...
edgecrusher Posted March 28, 2018 Report Share Posted March 28, 2018 Although I doubt I will ever use them, thanks. out of curiosity are your percentages by weight or volume? Quote Link to comment Share on other sites More sharing options...
Guest DiyEngineer Posted March 28, 2018 Report Share Posted March 28, 2018 volume, thank you for asking a question no usually responds to my formulas, I'll add a note in my next formula to use volume. Quote Link to comment Share on other sites More sharing options...
alsworms Posted March 28, 2018 Report Share Posted March 28, 2018 That formula is amazing! I remember several years ago researching how to make plastisol........and researching..........and researching......and finally gave up. This just might be something I'll want to dabble in my soon-to-be retirement days. Thanks for the info! Quote Link to comment Share on other sites More sharing options...

goldenshinner Posted March 31, 2018 Report Share Posted March 31, 2018 Out of curiosity, is there any off the shelf substitutes for dnip, or pvc paste, that can be obtained at hardware store or automotive store? Quote Link to comment Share on other sites More sharing options...
Driftwood Posted March 31, 2018 Report Share Posted March 31, 2018 Say I want to mix 40 gal. Are the materials readily available in small quantities as this? Quote Link to comment Share on other sites More sharing options...

Guest DiyEngineer Posted April 2, 2018 Report Share Posted April 2, 2018 (edited) DNIP is not readily available at most retail stores except in ones specializing in plastics, industrial materials, or lab materials such as grainger industrial co. since you are making this amount i would recommend looking for local non-order retail stores that might reduce costs, if not try ordering online.

OldHighlander Posted April 10, 2018 Report Share Posted April 10, 2018 Hi DIY, Can you share the source info and grade for your e-pvc? Also order of addition and processing temperatures would be helpful. Thanks Quote Link to comment Share on other sites More sharing options...
Guest DiyEngineer Posted April 11, 2018 Report Share Posted April 11, 2018 Highlander, i use the seventh grade or PG680 type from the site, here is the site i buy it from https://www.scgchemicals.com/en/products-services/product-type/pvc/pvc-paste-resin. Order of the way you add ingredients is (I assume your are asking this) E-PVC paste resin,and Tin Stabilizer then place it in the container you want to heat the mixture in then add the DINP, one third of the oil, with the dispersent, turn the heat to roughly to 360-375 degrees Fahrenheit, leave it for 20 seconds (with stirring) then stir in black sand and afterward mold or shape and then coat with the oil. Thank you for asking. Quote Link to comment Share on other sites More sharing options...
