SaBoFlex Fluo Blue – Plastisol Liquid Colour

Product detailed description

SaBoFlex Fluo Blue is a concentrated fluorescent pigment paste for colouring plastisol when making soft lures. It provides a vivid fluorescent blue shade for whole lures, backs, bellies, side stripes and high-visibility details. This is a colouring concentrate intended for mixing into base plastisol – it is not ready-to-use plastisol, airbrush paint or a surface coating.

Fluo Blue produces a vivid fluorescent blue shade. The final appearance varies with the dose, base plastisol, casting thickness, other additives and lighting. The concentrate in the bottle and an on-screen photograph are therefore not exact colour references for the finished lure; use a thin cooled drop or a test casting made with your own plastisol.

The term Fluo identifies this product as part of the fluorescent range. It does not mean phosphorescent afterglow in darkness, nor does it independently guarantee a particular response under a specific UV lamp. Standard Blue is a basic blue from the standard range, Aqua Blue is a separate special shade with no declared fluorescent effect, and Transparent Blue has its transparent character stated in its name. These products are not automatically interchangeable with Fluo Blue. Without a technical data sheet, we do not claim that it contains nanoglitter or has a metallic, pearlescent, precisely defined opaque or transparent, or non-bleed formulation.

For this pigment paste, SAF recommends adding small increments to plastisol that is already hot and clear. Its true intensity is difficult to judge in a cold, milky-looking base. In clear working plastisol, you can follow the shade as it develops and increase saturation gradually. Prepare the plastisol in accordance with its manufacturer's temperature and safety instructions and do not overheat it.

We do not specify a universal number of drops per 100 g. Drop size varies with the dispensing nozzle, and the same dose can look different in another plastisol or casting thickness. Begin with a small amount: a pale mixture can be coloured further, but added concentrate cannot be removed. For repeatable production, record the weight of plastisol, colour dose and every other additive.

Use Fluo Blue across a complete body or for a vivid blue back, belly, side stripe, tail or smaller strike point. In a laminate, trial it with white, pearl, silver, black, smoke or purple. A suitable heat-resistant silver, blue or holographic glitter can add flash, while black creates stronger spot contrast. Add glitter only after establishing the base colour and test the recipe in a small batch.

The 50 g option is practical for trying the shade, producing smaller batches or maintaining a broad workshop palette. The 250 g bottle is better suited to regular production or repeated recipes; the greater mass of paste also makes the complete bottle easier to homogenise by shaking. Pack size does not change the concentration or recommended method of use.

Storage and condition of the packaging

The colour paste and base plastisol are not the same material from a storage perspective. In SAF workshop use, Fluo Blue remains easier to handle in a cooler environment than plastisol itself, but the manufacturer does not publish a precise minimum storage temperature. Do not therefore treat the colour as frost-proof. Store it upright, tightly closed and dry at a stable room temperature, away from direct sunlight, heat sources and frost. Allow a chilled, unopened bottle to return naturally to room temperature before opening, then homogenise it thoroughly. Do not warm it on a radiator or hotplate or in a microwave.

Packaging note: Particularly after transport, a light oily film may appear around the thread of a concentrated pigment paste, or a mark may develop on the label even when the bottle is closed. Provided there is no evident loss of contents, this superficial trace does not affect use of the colour; we apologise if the label is marked. After dispensing, wipe the nozzle and thread, retighten the cap and store the bottle upright, ideally in a washable tray or sealed bag.

Frequently asked questions about SaBoFlex Fluo Blue

How does Fluo Blue differ from Standard Blue and Aqua Blue?

Fluo Blue belongs to the fluorescent range. Standard Blue is a basic blue from the standard range, while Aqua Blue is a separate special shade with no declared fluorescent effect. Compare the exact colour in cooled castings made from the same plastisol.

Is Fluo Blue the same as Transparent Blue?

No. Transparent Blue has its transparent character stated directly in the name. Without a separate technical sheet, we do not define the precise transparency or opacity of Fluo Blue, so the two should not be treated as direct substitutes.

Should Fluo Blue be added to cold or hot plastisol?

SAF recommends adding it in small increments to plastisol that is already hot and clear. Mix slowly but thoroughly after every addition, then check the shade on a cooled sample. Do not overheat the plastisol.

How can I keep the blue tone free from a green or purple shift?

Use a clean vessel, nozzle and stirring tool with no residue from yellow, green, pink or red pigments. Assess Fluo Blue on its own before trialling any additional colour in small increments.

Which layers can be combined with Fluo Blue?

White, pearl or silver can produce a lighter contrast, while black or smoke gives a darker division. Purple can create a closer colour transition. Cast a small test batch before scaling up any combination.

Does Fluo Blue also glow in the dark or guarantee UV response?

Fluo identifies the fluorescent range, not phosphorescent afterglow. The available manufacturer information does not separately guarantee performance under a particular UV lamp. For afterglow, choose a product that expressly states Glow in the Dark.
