LURE PLASTISOLS Lure Plastisols are very low durometer plastisols used for making fishing lures, bait, worms; e.g., artificial worms, eggs, crawfish, berries, squid, etc. The 3 main plastisols listed below are supplied as thin, clear liquids which when heated to 350 deg F will cure into a soft solid worm or other bait configuration. To make colored worms or lures , purchase small amounts of Pigment Concentrate (note: a 2% add of pigment concentrate is sufficient to color the lure plastisol). Stir in the pigment just prior to curing. For Curing instructions, see below. To make your own Aluminum filled epoxy molds see EHV-2911 casting resin.
Call 1-800-321-0170 for technical information. e-mail roy@qcminds.com There are 6 main products for making lure plastisols: 1. P0022 Grub Base : Durometer S-80 2. P0010 RB Regular Lure Plastisol : Durometer: S 88 3. P0014 Egg Base Plastisol : Durometer: S 62 4. RD-66 High Stretch Reducer/Softener 5. RD-55 Reducer/Softener 6. P7002 Hardener To see an excellent Lure Manufacturer that uses these products, see b2squid.com For regular lures, use P0010 RB lure plastisol and for extra soft lures use P0014 soft lure plastisol. Either one of these products can be customized: to make them softer, add 1 to 15% RD-35 Softener or 1 to 15% RD-66 (test for feel, softness and curability after each dilution): to make them harder, add P7002 hardener at 1 to 30% test for feel and hardness after each add). Other specialty grades of lure plastisol are available on request.
METHOD 1 The liquid plastisol is poured into a cavity mold and heated in an oven at 350 deg. F. until cured. After the mold has cooled to almost room temperature the lure can be removed from the mold. When hot, the lure is extremely weak and actually remains semi-liquid for a long time until cooled. In this instance the mold must have sufficient heat resistance to withstand baking at 350 deg. F. See Mold-making. METHOD 2 Hot Pot Method. The Plastisol is stirred in a hot pot at 350 deg. F. until cured. The liquid goes through an initial taffy-like gel stage and when up to temperature and cured returns to a clear cured liquid. This is poured off from a spigot into a cold mold. After the molded Plastisol has completely cooled, it can be removed from the mold. in this case, the molds do not require high heat resistance, because the plastisol cools very quickly to room temperature. See Mold-making. NOTE: for an excellent source of HEATED STIRRING HOT POTS See http://www.wenesco.com/plastisol.htm and http://www.wenesco.com/dip.htm#diptop Wenesco makes good Hot Pots for curing Plastisol to a liquid molten state, and then pouring out into cold molds. You can call them at 1-800-233-4430 or direct: 773-463-9200 . Ask for Brian Lowe.
Coloring of Lure Plastisols: See our full list of pigment pastes for color-tinting plastisol. Transparent colored lures can be made by stirring in carefully 0.1 to 0.3% of the pigment concentrate to the plastisol. Opaque colored lures can be made by carefully stirring in 2% of the pigment concentrate to the plastisol. See PIGMENTS PRICE LIST (below): MOLD MAKING Plastic molds can be made for making lures using our epoxy tooling resins (see separate brochure EPOXY TOOLING AND PATTERN MATERIALS SELECTOR GUIDE). Clear Molds: Use ELV-0010 resin with ECA-343 casting hardener at a ratio of 3 parts resin to 1 part hardener. Use this type of mold for cold molding lure plastisol: -pouring cured plastisol into the cold molds. Aluminum Filled Epoxy Molds: Use EHV-2911 Aluminum filled epoxy resin with ECA-408 casting hardener at a ratio of 8 parts resin to 1 part hardener. Use this type of mold for hot molding plastisol - pouring cold plastisol into a cold mold and then baking/curing in an oven until cured. SAFETY MEASURES: Good hygiene and safety practices are recommended. Also see the MSDS (Material Safety Data Sheet) for specifics on safety concerns. |
