Key Sentence: Hongye Silicone upgrades high humidity resistant mold silicone for stable curing in tropical and coastal production workshops.

Sep 11, 2026 — Many resin craft and candle mold producers in Southeast Asia struggle with incomplete curing and sticky mold surfaces caused by high ambient humidity. Ordinary condensation cure silicone reacts sensitively to water vapor, leading to inconsistent hardness and shortened mold service life. Hongye Silicone adjusts cross-linker and catalyst formula for its RTV-2 mold silicone to improve humidity tolerance. Even at relative humidity above 85%, the material cures fully without surface tackiness.

The upgraded mold silicone retains high tear strength and excellent detail replication, ideal for resin crafts, plaster ornaments and scented candle molds. It features low linear shrinkage, so finished molds can reproduce fine textures precisely. Each production batch undergoes accelerated aging and high-humidity curing testing before shipment. Clients in Malaysia, Indonesia and the Philippines have placed trial orders for craft mold production. Hongye Silicone supplies technical recommendations about workshop temperature and humidity control. This upgraded silicone helps tropical manufacturers reduce mold rejection rates and stabilize daily casting production.
