Softbaitfishing Cristallo STP Plastisol - HARD (5kg)

Product detailed description

What it is and what it’s for

Softbaitfishing Cristallo STP HARD is a plastisol used primarily as a hardener — typically mixed with softer plastisols when you want a firmer body structure and higher overall durability. A very popular workshop combo is MEDIUM + HARD for larger baits for sea fishing or strong current situations.

Key features (clear and practical)

→ floating across all hardness options
→ easy to mix, consistent behavior across batches
→ does not leave hardened PVC paste at the bottom, even after a few days
→ very high clarity, should not turn cloudy or absorb water
→ improved resistance to yellowing during repeated heating (when processed correctly)
→ stated to be low-odor / low-smoke
→ plasticizer phthalate-free
→ already contains a heat stabilizer (pre-mixed)

Workshop tip: mixing hardness levels (extra add-on)

→ MEDIUM + HARD: an ideal blend for larger baits when you want a stiffer body, more stability and a tougher build (sea fishing / strong current).
→ If the result feels too stiff, simply reduce the HARD ratio to bring the blend back toward a more flexible action.
→ Start with a simple 50/50 blend and fine-tune the ratio based on how you want the bait to move.

Basic heating notes

→ shake or stir well before use
→ heat slowly – pourable at approx. 160–200 °C
→ the goal is even heating without local “hot spots”

Microwave heating (clear step-by-step)

Microwave heating is fast, but it requires discipline. For better heat distribution, place the glass off-center (not in the middle) and use lower power.

Recommended workshop workflow:
→ Pour approx. 200 ml of plastisol into a 250 ml glass container.
→ Heat in short intervals on lower power, checking the transition from “milky” to gel stage.
→ Once the plastisol starts to gel, check more often (typically every few tens of seconds) and stir gently to spread heat evenly and avoid local overheating.
→ Continue until the plastisol is fully liquid and lump-free (this is the stage for final adjustments).
→ Add colors and glitters at the end – into fully heated plastisol. Stir only as much as needed for even dispersion.
→ If bubbles appear, let the mix rest briefly – they often rise and disappear.
→ Then inject/pour into the mold.

Workshop note (curing / shape memory)

After casting, it’s worth letting the baits cure at least overnight in a straight, unbent position to build proper “shape memory”. In practice, this is commonly done by:
→ laying baits on a flat surface so they don’t twist
→ curing them in water (baits float and don’t press against each other), just make sure they don’t end up bent against the container edge or water surface

Then briefly remove them, dry them, and continue with the next steps (degreasing, coloring, scents, etc.).

Safety

→ Heating plastisol produces fumes – use protective gear (gloves, long sleeves), and ventilate the area.
→ You are working with material around 170 °C, so serious burns are possible.
