Axel Plastics Research Laboratories have announced two new internal mould release additives for dicyanamide cured epoxy resins.
MoldWiz INT-1322 and INT-1329. By nature, DICY cured epoxies are among the most tenacious in their bonding properties, prompting many in the industry to search for more effective ways to release DICY epoxy, resins, compounds, prepregs and laminates.
According to AXEL’s Product Manager;
In the past, many internal mold release formulations proved ineffective, often killing the cure of the DICY resin and leaving the polymer under-cured and tacky” AXEL’s new proprietary formulations MoldWiz® INT-1322 has been proven to have no impact on the cure kinetics of immidizole or amine accelerated DICY. For non- accelerated DICY cured epoxy resin, AXEL offers INT-1329, which is formulated for the higher process temperatures associated with these DICY systems. Initial evaluations of these two new internal mold release additives indicates that they have a good pot life in resin mixes and provide good release from molds and substrates, making these new internal mold releases equally suitable for use in epoxy resin, epoxy compounds and prepregs.
MoldWiz INT-1322 and INT-1329 are, proprietary synergistic blends, composed of organic fatty amine and acid derivatives with surface active agents. The products are 100% active and generally effective at addition levels of 0.5-4 % based on resin system weight and dependent on process, fillers etc.[rssless][connections id=’221′][/rssless]
