Fillers, texture additives and colorants

Cabosil fumed silica, Q-Cell glass microspheres and milled fibers are distinct materials. The category also includes fine and medium non-skid additives and listed pigment products. Sharing a category does not mean these materials perform the same role or can be substituted at the same amount.

Start with the task and the specified resin system, then review the selected additive documentation.

Confirm the formulation before adding material

An additive can change how a resin mixture handles or how the finished surface appears. Confirm compatibility and the manufacturer instructions for the actual filler, pigment or texture additive selected; there is no single category-wide formulation.

Compare the listed package sizes and ask FPR about the specific resin and result you are working toward. For decorative dye and metallic-pigment sets, also browse Pigments & effects under Art & Specialty Resins.
