Zecai New Materials Silicone Color Masterbatch Formulated for Silicone Rubber Coloring Applications

Product Introduction

This silicone color masterbatch is a high-end colorant specially developed for silicone materials. It is refined through multiple processes including internal mixing, grinding and filtration, adopting high weather-resistant organic and inorganic pigments with food-grade silicone carrier. The pigments are fully dispersed with high tinting concentration and fast coloring efficiency. Hardly causes color grains, spots, flow marks and streaks after mixing, stabilizing product appearance and reducing rejection rate. Compatible with platinum curing systems, it has excellent compatibility with solid compression silicone, liquid injection silicone and extrusion silicone. It will not affect curing speed or impair silicone’s original physical properties including elasticity, tensile strength and resilience. It is non-migratory, non-bleeding and non-blooming after molding, no precipitation to contaminate contact surfaces. Stable at -60℃~230℃, with great anti-yellowing and UV aging resistance. Color remains stable under high-temperature baking or outdoor exposure. Strict batch color difference control ensures reliable color repeatability. Custom color matching is available. We develop colors according to your swatches, Pantone codes or samples for various special color effects. Eco-friendly raw materials, direct factory supply with technical support, a stable coloring solution for silicone product manufacturers.

Product Advantages

Excellent dispersion: Superfine grinding process, uniform dispersion, no particles or white spots, avoid color streaks and spots

No impact on curing: Compatible with platinum curing system, will not delay curing or change silicone physical properties

Non-migration & non-blooming: Pigments are stably locked inside silicone, no bleeding, precipitation or blooming

Superior weather resistance: Anti-yellowing, UV-resistant, wide temperature resistance, color fastness for long service

Stable color repeatability: Precise formula control, minor color difference between different batches for same color code

Flexible color customization: Solid, translucent, fluorescent, luminous, pearlescent, metallic colors available

Eco-friendly & safe: Free of heavy metals, phthalates and PAHs, qualified for compliance tests

Easy to use: Directly mixed with silicone raw material, no extra additives required, wide dosage range

Stable supply: In-house production line, accept small trial orders and bulk orders with controllable lead time

Widely applied for all platinum-cured silicone products:

▫️Silicone baby products: nipples, feeding spoons, plates, teethers

▫️Silicone kitchenware: spatulas, scrapers, food covers, baking molds

▫️Sealing parts: waterproof gaskets, silicone sheets, tubes

▫️Consumer electronics: silicone keypads, protective cases, shockproof parts

▫️Gifts & ornaments: silicone bracelets, pendants, keychains

▫️Medical & hygienic silicone accessories (color matched as required grade)

▫️Silicone products by compression molding, extrusion and injection molding

Instruction

1. Recommended dosage: 0.2%–3% normally. Increase dosage for dark & high-opacity colors; low dosage for light translucent colors
2. Mixing method: Add directly into silicone raw material and mix fully. Proper mixing time for uniform color
3. Processing: Suitable for compression molding, extrusion, liquid injection molding of platinum-cured silicone
4. Color matching suggestion: Make trial sample first. Confirm color, heat resistance and anti-migration performance before mass production
5. Storage: Keep sealed in cool, dry and dark place, away from direct sunlight and high temperature

Notes

1. Only for platinum-cured silicone. Not compatible with peroxide curing system, mixing will cause curing failure
2. Different silicone base and curing agent from different brands may slightly affect final color. Stable raw material system is recommended
3. If for food contact or medical use, please inform us before order, we will adopt corresponding grade raw materials
4. Product thickness, molding temperature and baking time may slightly affect final color. Confirmed sample shall be the standard
5. Avoid random blending with other masterbatches or additives, to prevent poor dispersion and precipitation

Compliance

Test reports are available. Support ROHS, REACH, FDA food contact tests to meet export standards of Europe and America.
