SiliPig high-concentration silicone pigments — intense, blendable colors for platinum-cure and tin-cure silicones

SiliPig is a line of professional silicone-based pigments formulated to disperse easily and produce rich, uniform coloration in cast or brush-on silicones. Use SiliPig to tint parts, highlight details, create visual layers, or develop consistent branded colors for your silicone products.

• High-strength pigments for vivid and repeatable coloration.
• Designed specifically for silicone — excellent dispersion with no graininess.
• Compatible with platinum-cure and tin-cure silicone systems (not compatible with resins and epoxies).
• Blendable palette to create custom hues, tones, or tints.
• Low dosage: typical use 0.1%–3% by weight.
• Each 25g container is good for up to ~14kg of silicone!

Important: Some containers may have minor dents caused during international transport. The yellow pigment is supplied in a transparent container instead of the standard metal one, due to manufacturer packaging differences.

Mixing

• Pre-stir the pigment (natural settling may occur).
• Mix silicone Part A + Part B first, until uniform.
• Add SiliPig to the fully mixed silicone, then stir thoroughly until evenly dispersed.
• Typical dosage: 0.1%–3.0% (see table below). Higher pigment loads deepen color and may slightly increase viscosity.

Specifications

• Type: silicone-based, high-strength pigment
• Appearance: highly pigmented, paste-like liquid
• Compatibility: platinum-cure and tin-cure silicones
• Recommended dosage: 0.1%–3% (max. 5% for special effects)
• Mixing method: add pigment after A + B are thoroughly mixed
• Effect on cure: minimal at recommended loadings
• Viscosity: may increase slightly with higher pigment percentages

* “% by weight” means: for 100 g of fully mixed silicone (A + B), 1% pigment = 1 g of SiliPig pigment. Example: 250 g silicone → 1% pigment = 2.5 g SiliPig.

Color range & blending

• Primary, secondary, and neutral pigments available.
• Mix primaries to create custom hues.
• Add White for tints and Black for shades.
• Record pigment ratios by weight for repeatability.

Available Colors

The SiliPig line is available in the following high-strength pigments. Each color includes a reference to its closest Pantone match for predictable and repeatable color formulation:

Good practices

• Use a precision scale for repeatable color formulation.
• Scrape sides and bottom of the cup while mixing to avoid streaks.
• For marbling effects, under-mix slightly and pour immediately.
• Clean tools promptly with silicone-safe cleaners.

Always perform a small-scale test when first combining SiliPig with your silicone system. SiliPig pigments are skin-safe but not suitable for food-grade silicone applications.

Storage

Store tightly sealed, in a cool, dry environment (18–25°C) and avoid direct sunlight and moisture.
