Black Silicone Color Masterbatch from Zexin, a Concentrated Pigment for Silicone Coloring

This black silicone color masterbatch is a high-end coloring material specially developed for silicone products. It adopts high-performance carbon black pigment with silicone carrier, and is refined through internal mixing, grinding and filtration procedures. The pigment is fully dispersed to deliver strong tinting power and pure black shade. It helps you avoid common defects such as color spots, flow marks and uneven color, stabilizing the surface appearance of finished silicone parts and lowering the reject rate.

It is compatible with platinum curing silicone systems, including solid compression silicone, liquid injection silicone and extrusion silicone. It will not interfere with the vulcanization reaction or damage the original physical properties of silicone. After molding, it features stable color locking, no bleeding, migration or blooming. It has outstanding heat resistance and weather resistance, and maintains consistent black tone under high-temperature processing and long-term service. Batch color difference is strictly controlled to guarantee stable color repeatability.

We suggest conducting sample tests under your actual compounding conditions first to confirm the proper dosage and calculate material cost. Complete test documents can be provided for compliance verification. We support sample delivery and customized solutions for your production demands.

Instruction

Recommended dosage: 0.5%–2% by weight, adjust the proportion to reach your target blackness Mixing method: Add directly into silicone raw material and fully knead according to your existing compounding process Test suggestion: Make trial samples first. Check dispersion, surface appearance and vulcanization status before mass production Cost calculation: Confirm the final mixing ratio from trial samples to work out accurate material cost Storage: Keep sealed in cool, dry and shaded environment, avoid direct sunlight and high temperature

Notes

This masterbatch is mainly suitable for platinum curing silicone. It is not recommended for peroxide curing systems without pre-test. Different silicone base materials and curing agents may affect the final coloring effect. Always run verification under your actual production process. Test coverage and applicable scope are subject to the official test report. Product thickness, molding temperature and baking time may influence the final appearance. The approved sample shall be the standard. Do not mix randomly with other color masterbatches or additives to prevent poor dispersion and precipitation.

Compliance

Test reports can be provided upon request. Available inspection items include national standard items, RoHS, REACH, halogen, FDA and LFGB, meeting export requirements for Europe and America.
