The materials are in stock and are shipped within 1 to 2 days by UPS or freight truck.
The gallon plastic jugs are similar to the bleach bottle shape which makes for easy shaking and pouring (metal paint cans always leave residue in the can lip that dribbles down the side). The five gallon container is a heavy duty translucent, plastic, rectangle with an on/off pour spout. This makes it convenient to place on its side while pouring without rolling off the table. We pack all these containers in boxes for shipping. Material Safety Data Sheets come with the products.

Our resins are very thin, similar to water, not thick like some resins that have the consistency of cold honey. Most of our resins are mixed 50/50 by volume. This makes it easy to use 'as is' or when adding equal amounts of our fillers. The thin resins mix easily and give good reproduction detail, look at the pictures of castings in the brochure. The R1 FAST CAST® resins do not contain fillers.


PURPOSE: For use as a high quality filler in R1 FAST CAST® resin to extend the resin, decrease the part weight, improve the physical qualities such as dimensional stability and make it possible to cast unlimited thickness (using #709) in one pour without exothermic cracking. USES: Blend with the resin 50/50 by volume to make decorative castings.  A high load of filler will turn the resin into a putty consistency. This filler has very high quality consistency, low moisture content and due to these reasons, actually makes the finished casting less expensive in the long run than using less expensive similar fillers. Quality control pays. Always keep containers closed to avoid moisture contamination. 1 Gallon2 Gallon, 5 Gallon


PURPOSE: For use as a very high quality filler for R1 FAST CAST®  to strengthen the finished casting, increase the density, minimize shrinkage (less than 1/32" in 12", 50/50 volume blend), create a glass smooth cell structure and make unlimited thickness in one pour without cracking with FAST CAST® 709. The HG3000 FILLER is manufactured under rigid QC methods and has such a low moisture content that it will not cause resin problems as do other similar fillers. Again, this is where good quality control saves through less rejects. We have tested many brands and types of fillers and we only accept the best. USES: Blended 50/50 by volume with our #709 resin to make composite tools, patterns, reference fixtures, vacuum forming and plug assist tools and industrial castings.

P1 Easy Green FILLER®

PURPOSE: For use as a filler only with our #709 or #891 resins (50/50 ratio by volume) to make a nonabrasive finished product. The P1 is used to make prototypes and proof CNC machining. Cannot be painted. The density of the resin remains almost the same with the filler added. 1 Gallon, 2 Gallon, 5 Gallon
