Resin Fillers, Pigments and Dyes

When using epoxy or polyester resins for repairing plastic or creating new items, you sometimes need plastic fill, dyes and other additives to achieve the desired results. When it comes to increasing the bond strength between two materials, making them stronger or getting them to look the way you want, TAP Plastics is the ultimate source for supplies. We offer a variety of resin plastic filler and dye products for strong, colorful and lasting plastic.

With over 70 years of experience in plastic fabrication and distribution, we understand just how vital it is to have the tools you need to complete any project with confidence. Whether you’re about to start your first plastic project or your 1,000th, we carry the right epoxy filling supplies and have the knowledge to help you use them correctly.

Customize Your Epoxy or Polyester Resins

One of the most versatile products we supply are plastic filler resins. When added to polyester or epoxy resins, these fillers can dramatically change the properties of the final product and make resins thixotropic — i.e. temporarily change the thickness to make the resin more workable — without increasing viscosity. TAP Plastics has an assortment of plastic epoxy fillers that can be added to epoxy, polyester resin and other common fabrication materials. We developed TAP Cab-O-Sil to make resin harder and stronger while reducing sag. Cab-O-Sil is a synthetic, hydrophilic amorphous silica that can be applied as a thickening and thixotropic agent in unsaturated polyesters, coatings, printing inks, adhesives, cosmetics, and other products. Cab-O-Sil controls sag and allows work on overhead surfaces. We offer several sizes to choose from, so you can stock up or save on just enough for your needs.

TAP Microspheres hollow glass spheres can be used as an epoxy plastic filler that adds air particles to solid materials to lower their total weight. This white filler can displace up to six times the resin’s normal weight while making it easier to fabricate and sand down. We also have TAP Milled Glass Fibers which are designed to increase mechanical, impact, tensile, flexural and compressive strength. Commonly known as E-glass, this efficient resin filler also improves dimensional stability and can be combined with Cab-O-Sil when you need a non-sagging resin for overhead use.

Need a solution that increases the structural strength and stability of resin? Look no further than TAP Chopped Fiberglass. This epoxy fiberglass filler reinforces resin, makes the final product harder and reduces shrinkage. If you’re trying to lower the overall costs of a resin casting or repair project, use Talc filler powder. This heavy gap filler lowers shrinkage and generates less heat during the curing process.

Simple Plastic Resin Tinting

While stocking up on resin filler, remember to check out our collection of resin dye. Our own premium pigments can be used for coloring fiberglass-reinforced plastics, polyester, or epoxy. When doing epoxy fabrication and repair in high-visibility areas, the right epoxy dye can greatly improve the optics. Use our assortment of epoxy pigments and dyes for everything from boat repairs to casting custom jewelry.

We also offer a vast collection of plastic dye colors that can be customized to suit a specific application. Multi-color Mica Pigment Powder packs give deep pour resin a pearl-like shine that is ideal for jewelry and river tables. Our set includes one dozen resealable packets with an easy-to-use scoop. Are you performing repair work? Blend any colors to create any hue on a color wheel.

If you need solid colors, use TAP Premium Opaque Pigments. These pastes can be added to epoxy, polyester, polyurethane or vinyl ester. For a transparent or translucent color in casting resin, add transparent resin dyes. How bold the color is depends on how much pigment or dye is mixed in, so experiment to find the perfect shade. TAP Super Pigments are concentrated and pourable, making them a smart solution for casting rubber parts, models, and more. We offer a wide variety of epoxy dye colors to choose from, so you can find the best solution.
