Greetings!
Welcome to the July 2011 issue of Freeman's E-Newsletter.
Boy, acquisitions are a lot of work!! Needless to say, many of our other projects, such as our new videos, have been temporarily put on hold as we continue to integrate the several divisions of the old Kindt-Collins into the new Freeman. But we're making a lot of progress every day and we should be back to normal soon.

The Latest on the Kindt-Collins Acqusition
|
|  Browse through our website and you'll see a number of new product pages, most notably Dynacast fast-cast urethanes, Master Sure-Lock alignment dowels, and Aluminum Pattern Letters w/ sprigs.
We have a number of other new products to share in the coming months, many of which will be featured in upcoming newsletters.
We are also at work on a new website dedicated to our wax products, both old and new...stay tuned.

| 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)
I am spraying PVA on top of a gel coat as part of a repair process, but the PVA seems to be "attacking" the gel coat. What is happening?
Two things are probably happening. The gel coat may not have been allowed to set up properly (it is not hard enough) and the PVA is penetrating its surface. Also, you may be too close to the gel coat surface while spraying and air pressure in the spray-gun is forcing the PVA into the gel coat. Spray a distance that allows PVA to atomize (mist) completely before coming in contact with the gel coat.
What is the post cure schedule of Freeman 917, and what are the max temperatures in which I could use the PVA, Wax Release, and PS Tape?
The recommended post-cure for the Freeman 917 is as follows:
Two Hours at 150°F on the mold if possible
Two Hours at 200°F
Two Hours at 250°F
Two Hours at 300°F
The PVA, Wax Release, and PS Tape cannot handle elevated temperatures. After your Freeman 917 has cured 16-24 hours at room temperature, remove from the mold. Clean off all the PVA, Wax Release and PS Tape with soap and water. Once you have cleaned the surface, put the mold back onto the pattern, and begin your post-cure.
We are making composite blade wind turbines. The blade is about 40 inches long and currently made by metal stamping. The cross section of the stamping is uniform and not the best for aero efficiency. Do you have any products that would able to be developed into a wind turbine blade.
We would suggest machining the master from RenShape 440. The surface can be smoothed easily with #60 Pattern Coating. MiaPoxy 100 can be used to do your lay-up off of the master to create your molds. You can then use the Miapoxy 100 to create your final part as well.
We reverse engineer impellers and then make new ones in metal castings. In order to reverse engineer the impeller vane curve and shape, we want to pour a product into the vane area (between 2 vanes), let it solidify, then pull it out. I am assuming that it will spring back to the original shape and I can then measure and draw the curve of the vane.
We would suggest you take a look at our Bluestar V-330 or V-340 Silicone Rubber. The material is flexible, but it will return back to its original shape. We would also suggest using a coat of wax release for easier removal.
