Epoxy Resin Pigment

Epoxy resin pigments are colorants added to epoxy resin systems to impart color and aesthetic effects to finished castings, coatings, and other epoxy-based creations. They are crucial for both functional and decorative applications.

Material Types

Epoxy resin pigments are broadly categorized by their chemical composition and form:

• Liquid Pigments: These are concentrated colorants typically composed of dyes dissolved in a solvent or carrier liquid. They offer high tinting strength and are easily mixed into the resin. However, they can sometimes affect the curing process if used in excessive amounts.
• Powder Pigments: These consist of finely ground solid colorants, often metal oxides, phthalocyanines, or carbon black. They require thorough mixing to achieve even dispersion and prevent settling. Powder pigments generally exhibit better lightfastness and heat stability than liquid pigments.
• Mica Powders: These are natural mineral pigments composed of flakes of mica coated with titanium dioxide and/or iron oxides. They create pearlescent, shimmering, or metallic effects.
• Glitter: Small particles of reflective material (often plastic) used for decorative effects.
• Pastes: A combination of powder pigments and a carrier medium, offering a balance between tinting strength and ease of use.

Purpose & Function

• Coloration: The primary function is to provide a desired color to the epoxy resin.
• Aesthetic Enhancement: Pigments enable a wide range of visual effects, including solid colors, translucent hues, pearlescence, metallic finishes, and special effects like marble patterns.
• UV Protection: Certain pigments, like carbon black and some iron oxides, can absorb UV radiation, protecting the epoxy resin from degradation.
• Functional Properties: Some pigments can impart properties like conductivity (e.g., aluminum powder) or increased hardness.

Usage Scenarios

• Resin Art: Creating decorative items like jewelry, coasters, paintings, and furniture.
• Flooring: Coloring epoxy floor coatings for both aesthetic and functional purposes (e.g., anti-slip properties).
• Coatings & Adhesives: Adding color to protective coatings, industrial adhesives, and encapsulating materials.
• Molding & Casting: Coloring epoxy castings for figurines, prototypes, and industrial parts.
• Wood Finishing: Creating colored epoxy river tables and other wood-resin composites.

Common Types & Effects

• Acrylic Pigments: Versatile, water-based pigments suitable for a wide range of applications.
• Alcohol Inks: Highly concentrated liquid pigments that create flowing, translucent effects.
• Pearlescent Pigments: Create shimmering, iridescent effects. Often based on mica.
• Metallic Pigments: Provide gold, silver, bronze, or copper finishes. Typically aluminum or bronze powders.
• Fluorescent Pigments: Glow under UV light.
• Phosphorescent Pigments: Glow in the dark.
• Translucent Dyes: Allow light to pass through, creating vibrant, see-through colors.
• Opaque Pigments: Provide solid, non-translucent colors.

Considerations

• Pigment Load: Adding too much pigment can interfere with the epoxy resin's curing process, resulting in a soft, tacky finish.
• Dispersion: Thorough mixing is essential to ensure even color distribution and prevent settling.
• Compatibility: Ensure the pigment is compatible with the specific epoxy resin system being used.
• Lightfastness: Some pigments fade over time when exposed to UV light.
• Safety: Wear appropriate personal protective equipment (PPE), such as gloves and a respirator, when handling pigments.

Epoxy resin pigment typically refers to pigments dispersed in a nonaqueous medium, used in the manufacture of paints, including enamels, and stamping foils. Additionally, it could involve the epoxy resin itself as a primary form material.

Here are the relevant HS codes based on the provided reference material:

• 3208900000: This HS code covers paints and varnishes (including enamels and lacquers) based on synthetic polymers or chemically modified natural polymers, dispersed or dissolved in a nonaqueous medium; solutions as defined in note 4 to this chapter; other. This could apply if the pigment is already incorporated into a paint or varnish formulation using epoxy resin. The total tax rate is 58.2% (Base tariff: 3.2%, Additional tariff: 25.0%, Post-April 2, 2025, additional tariff: 30.0%).
• 3212100000: This HS code covers pigments (including metallic powders and flakes) dispersed in nonaqueous media, in liquid or paste form, of a kind used in the manufacture of paints (including enamels); stamping foils; dyes and other coloring matter put up in forms or packings for retail sale: Stamping foils. This applies if the pigment is specifically in the form of stamping foils. The total tax rate is 59.7% (Base tariff: 4.7%, Additional tariff: 25.0%, Post-April 2, 2025, additional tariff: 30.0%).
• 3212900050: This HS code covers pigments (including metallic powders and flakes) dispersed in nonaqueous media, in liquid or paste form, of a kind used in the manufacture of paints (including enamels); stamping foils; dyes and other coloring matter put up in forms or packings for retail sale: Other Other. This applies to pigments not specifically classified as stamping foils. The total tax rate is 58.1% (Base tariff: 3.1%, Additional tariff: 25.0%, Post-April 2, 2025, additional tariff: 30.0%).
• 3907300000: This HS code covers polyacetals, other polyethers and epoxide resins, in primary forms; polycarbonates, alkyd resins, polyallyl esters and other polyesters, in primary forms: Epoxide resins. This applies if the product is the epoxy resin itself in its primary form. The total tax rate is 61.1% (Base tariff: 6.1%, Additional tariff: 25.0%, Post-April 2, 2025, additional tariff: 30.0%).

Important Note: The classification depends on the specific form and composition of the product. If the pigment is a component within an epoxy resin formulation, 3208900000 may be appropriate. If it is the pigment itself, either 3212100000 or 3212900050 would be considered, depending on whether it is a stamping foil. If it is the epoxy resin in its raw form, 3907300000 applies.
