Why does silicone rubber produce bubbles after adding the curing agent?

This is a normal physical phenomenon. The liquid produces many bubbles during mixing, so vacuum exhaust bubble treatment is required.

AI-Powered supplier vetting

SummaryGuangzhou OTT New Materials Co., Ltd. is a China-based limited company established in 2014, operating in silicone and related chemical materials. It reports five production lines, a 1,700 m² manufacturing plant, broad product coverage, exports representing 90% of total sales, and stated peak- and off-peak-season fulfillment within 15 working days. The supplier holds ISO 9001:2015 certification and describes technical support, after-sales service, and silicone-material innovation capabilities. However, the available information indicates a relatively small organization of 17 employees, fewer than five quality-control staff, and limited documented customer-trade evidence. Financial strength, customization performance, and the depth of customer cases cannot be conclusively assessed from the provided data.
