Best Practices for Elantas (Altana) TU-961
-
Surface Preparation
Before mixing the Conathane® TU 961, the mold to be used should be thoroughly prepared. Wood, concrete and other porous templates should be sealed with a high quality urethane such as MBT Form-Cote. The pattern should be free of any dirt, dust, or standing water due to Conathane TU 961's moisture sensitivity. To ensure a good release of the liner after hardening, apply a coat of a drying paste wax (car wax) to the mold. Then, buff the wax to a shine and top with a generous coating of Conap® MR 5002, a silicone based release agent
-
Mixing
Mix and weigh only in non-porous plastic or metal containers, avoiding paper containers or wooden sticks. The material should be close to room temperature prior to mixing. Weigh the desired amount of material in a ratio of 2 parts A to 1 part B. Pour the two weighed parts into your mixing container. Next, mix with a low speed paddle mixer or a plastic, metal or glass mixing rod for 2 minutes, being careful not to entrain air. Pour the mixture into a second container while scraping the sides, and mix again for a maximum of 3 minutes.
Note: Do not scrape the sides of the container when pouring the Conathane TU 961 onto the mold after the second mixing. For additional casting information refer to the Formliner Technical Application Guide or contact a Master Builders representative. During the initial curing process, Conathane TU 961 generates a great deal of heat. Use caution when handling the mold at this time.
