This article explains the application of concrete mold release agents in Indonesia and Southeast Asia precast industry. It focuses on how hot and humid climates affect demolding performance, surface quality, and production efficiency.

It compares oil-based, water-based, and emulsion types, and provides guidance for selecting the right product for different molds and construction conditions. Real industry cases from Indonesia show improved efficiency and reduced surface defects after optimization.

The article also highlights the role of PCE, HPMC, and Powder Defoamer, which together improve flowability, water retention, and surface quality.

Overall, the study shows that advanced release agent systems help precast factories improve productivity, reduce defects, and stabilize performance in tropical environments.
