Axel Plastics Research Laboratories Inc. has developed a water-based mold release effective for compression and resin transfer molding.
MoldWiz WB-2700 is a 10 percent active product that contains no hazardous materials, according to the Woodside, N.Y., firm. In one case for an aluminum-filled epoxy compression tool, spraying every three to five parts gave a cleaner mold and good release, Axel said.
In an RTM case history, the MoldWiz product replaced a two-component release system in a setup with aluminum molds processing epoxy and vinyl ester resins.
