Freeman has officially entered the SL market!!
Due to an exclusive arrangement with Huntsman Advanced
Materials, Freeman is now offering RenShape V1 and RenShape V2
Stereolithography resins for use on Solid State Laser SLAŽ Systems.
Both of these
products offer an outstanding blend of price and performance. These resins, without sacrificing
quality, are very well priced for today's highly competitive marketplace.
RenShape V1 is an excellent choice for generating QuickCast™ build style patterns while RenShape V2 is ideal for creating
parts that mimic Polypropylene. Call us at 800-321-8511 Ext 773 to learn more

Tech-Line Q & A |
|
In every issue, we bring you the answers to real-world technical questions that have broad applications. Our technical support staff is available during normal business hours, Monday through Friday, by calling 800-321-8511 (Option 5)
What can I use to thin the viscosity of my silicone rubber?
The 47V-50 Silicone Fluid is used to reduce the viscosity of the two-part silicone rubber. Add 5-10 parts by weight (10 is the maximum recommended) of the 47V-50 to 100 parts of silicone base (part A).
How can I increase the strength of the RTV silicone rubber?
The most commonly used method for increasing the physical strength of the silicone RTV materials is by adding 2.0-4.0 parts by weight (pbw) of fumed silica filler. However, doing so may thicken the material and require mixing special equipment to thoroughly disperse the additive.
What is the proper procedure to release epoxies/ urethanes from a porous pattern/ mold?
1. Make sure your mold is properly sealed.
a. Apply one coat of Freeman Wood & Plaster Sealer to the bare wood surface using a pure bristle brush and allow the material to absorb into the wood. b. After the first coast has dried (approximately half an hour), you will notice that the sealer has swelled the grain and made it rough. Use sand paper or Scotch-BriteŽ, lightly sand the surface to make it smooth again. Sanding is not necessary when working with plaster or sheet wax. c. Wipe off the pattern with a cloth and then apply a second coat of sealer d. After allowing the second coat to dry (preferably overnight), lightly sand the wood again and wipe it off with a cloth. e. You are now ready to apply the release agents. 2. Brush on a layer of Freeman Wax Release3. Allow coat to dry or immediately wipe off the excess with a cloth 4. We suggest at least two coats of Wax Release to make sure your entire part is covered evenly. 5. Next, you will need to apply two layers of Partall PVA Mold Release. 6. Each coat will require a half hour of drying time unless you use a fan or air hose. 7. After the second coat of PVA has dried thoroughly, apply a final coat of Freeman Wax Release. 8. Buff this last coat gently so as not to break through the layers of the PVA.
Customers have had success with the above procedure, but it is always a good idea to test before using any type of release procedure before proceeding with project.
Can I use lumber or plywood to make a core in a cast epoxy/ polyurethane thermoform tool so I don't have to use so much resin?
This is not a good idea. The wood core and the epoxy or polyurethane resin will expand and contract at different rates as the tool heats and cools. This will introduce stress into the tool during cycling. This could cause cracking that would require repair or replacement of the tool.
Additionally, lumber cores will dry out as they are heated during production runs. This drying out will lead to cracking, checking, and warping of the wood core. This will also introduce stress and most likely cause the tool to warp or crack. It is always good practice to cast a tool out of solid resin. If tool size makes this impractical, then reconsider the tool construction technique. Perhaps the tool should be made using fiberglass and laminating epoxy.
