Greetings!
Welcome to the January issue of Freeman's E-Newsletter!
Finally...our new Miapoxy website is live!!
As anyone who has ever dabbled in the wonderful world of web design and online shopping carts can attest, this isn't easy. We still have a bit of work to do over the next few months to get it just right, but we've made the switch...HobbyCast is now closed and Miapoxy is now open!
So while we are live, we don't think for a minute there won't be minor issues and inconveniences. In other words, "please pardon our dust". That's why we are extending a special 10% discount for everyone's first miapoxy.com order - use coupon code dusty10...but hurry as this will expire next Friday (1/15/10, ...that's 15/1/10 for our Canadian customers)

 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 is the estimated useful life of silicone rubber at elevated temperatures?
Service Temperature - Useful Life
250°F - 10-20 Years
300°F - 5-10 Years
400°F - 2-5 Years
500°F - 1 Week
600°F - 6 Hours
700°F - 10 Minutes
800°F - 2 Minutes
Is there something I can use to protect my unused urethane after I have opened the container?
Our Freeman 302 Urethane Protectant can be used to preserve and prolong the usable life of moisture sensitive polyurethanes.
Can I use dissimilar RenShape boards on high temperature applications?
We would not recommend using tooling boards with different coefficients of thermal expansion because doing so can cause stress on your pattern.
What adhesives can I use for bonding foundry cores?
We would suggest either our Tecbond 501 or Tecbond 601. The 501 has a low viscosity for easy flow and can handle temperatures up to 145-150°F. The 601 has a higher viscosity and faster set up time compared to the 501, but the 601 can handle temperatures up to 185°F.
