AI Technical Summary

⚠Technical Problem

Existing release agents suffer from problems such as low adhesion, uneven distribution, and poor atomization in micro-spraying processes, failing to fully leverage the low waste liquid generation advantage of micro-spraying processes.

⚗Method used

A mold release agent for micro-spraying was prepared by using a specific modified silicone oil and zinc dialkyl dithiocarbamate in combination, which worked synergistically to improve the adhesion and high temperature resistance of the mold release agent. Furthermore, by selecting a specific compatibilizer to improve the dispersion and dissolution ability, a mold release agent was prepared.

🎯Benefits of technology

It improves demolding performance, reduces the amount of mold release agent, reduces mold frame adhesion and oil mist generation, improves production efficiency and stability, and significantly reduces waste liquid volume.
