The Landscape of Sealant & Adhesive Manufacturers in China
Many sealant manufacturers in China serve both domestic and international markets, offering OEM, private labeling, and specialty formulations.
Here are the main categories of sealants produced in China:
1. Silicone Sealants
These are the most popular in construction and architectural industries. Siway, for example, produces high-performance silicone sealants used in skyscrapers, glass facades, and home interiors.
2. Polyurethane Sealants
Used in civil engineering, roads, and automotive applications, PU sealants offer excellent adhesion and elasticity.
3. MS Polymer Sealants
These hybrid sealants combine the benefits of silicone and PU, and are VOC-compliant, eco-friendly, and paintable.
4. Acrylic and Butyl Sealants
Typically used for non-critical or temporary sealing jobs. Though less flexible than silicone or PU, they offer cost-effective solutions.
