Hongye Silicone Launches High‑Humidity Resistant Mold Silicone

Hongye Silicone releases improved high‑humidity resistant RTV‑2 mold silicone, aiming to solve unstable curing and soft surface issues faced by mold‑making factories located in tropical and coastal high‑humidity areas. Ordinary condensation‑cure silicone tends to suffer incomplete cross‑linking under long‑term damp surroundings, resulting in sticky inner surface and shortened mold service cycle.

The adjusted formula optimizes cross‑linking agent system. The material maintains smooth curing process even under high‑temperature and high‑humidity working environment. After full cure, the silicone keeps good tear strength and fine‑pattern reproduction capability. It fits for producing molds for resin crafts, plaster ornaments and scented candles. Users can carry out vacuum defoaming to reduce bubble defects inside finished molds.

Supported by Shenzhen and Huizhou manufacturing plants, each batch goes through strict lab test on curing effect under simulated humid conditions. Handicraft buyers from Southeast Asia submit increasing sample orders for field verification. Hongye Silicone technical team provides complete TDS, MSDS documents as well as practical guidance about mixing proportion and operating environment suggestions. This silicone grade helps overseas factories reduce defective mold rate caused by climate factors, stabilize mass‑production output and cut material consumption in daily mold‑making operations.
