Key Sentence: Domestic silicone sealant manufacturers issued collective price increase notices on July 15, the third round of markup this year, with partial factories suspending new orders temporarily. On July 15, 2026, dozens of silicone sealant manufacturers across East China and South China released official price adjustment letters, raising all types of architectural and industrial silicone glue prices by 300–500 RMB per ton. The move comes after DMC prices remained volatile and the industry enforced 60% coordinated production cuts to curb oversupply, continuously lifting raw material procurement costs for downstream processors. Many medium-sized sealant enterprises even adopted partial order suspension policies to avoid further losses amid thin profit margins. General neutral silicone sealants face the biggest cost impact, while high-end low-VOC and new energy potting sealants hold stronger price transmission capacity. Industry insiders said the price wave will spread to overseas export silicone products in late July. Buyers will accept moderate price adjustments for compliant low-volatility silicone, while low-cost generic silicone orders will shrink obviously in the short term.
