Granatex Granite Effect Fillers
Choice of 30 granite-effect materials for solid surface manufacturing.

Granatex® 350 is an economical granite effect filler that offers more vibrant colors than similarly priced products on the market. It can be used without gel coat for densified solid surface flat stock or with gel coat for products used where water is present. Granatex 350 is pre-blended with ATH for your convenience and to assure color consistency. Simply add resin and catalyst, mix and pour.

Granatex 350 is "easy on your equipment" and can be blended by using conventional mixing equipment. The use of gel coat is recommended when significant water contact is anticipated. Whether behind gel coat or as a solid surface part, Granatex 350 is an ideal material of choice for shower pans, vanities, water closets, bidets, tubs, or accessories. Granatex has been engineered to minimize particle settling and part warpage. Granatex 350 has the added benefit of being a lightweight filler resulting in high volume yields per square foot cast. Lower density results in lighter cast weights for your finished parts.

Granatex 350 is offered in 10 colors. Packaging is available in either 50 lb and 500 lb containers. Cast sample chips and 3 lb containers of Granatex filler are available upon request for evaluation.

Note: All attempts have been made to accurately demonstrate cast material in the images below. However, samples shown may vary from finished cast product, and may not precisely portray color, hue or granule size. Resin used will affect color hue of final cast product. Your monitor's color accuracy will affect the color hues shown. If a precise color match is required, order sample swatches of this product, or for the most accurate samples using your resin, order a 3 lb box of the material and cast it using your specific resin.

* Occasionally, certain material(s) may be available that are not within specification for our production requirements. These material batches are the same quality materials, but vary in some manner from our standard production specification. In certain cases, we will offer these limited batch runs of material at greatly discounted prices. If you have a limited casting requirement, you may find substantial savings by purchasing from our discrepant stock. Look for the "Discrepant Available" notice in the Granatex GTX material pages.
