وصف المنتج
Medium to High Silane Modified Polyether Polymer for Structural Sealants and Industrial Bonding
High Transparency Medium to High Modulus STP Polymer 35000-45000 mPa*s for Structural Sealants and Industrial Bonding
350A is a high-activity medium-high modulus STP polymer designed for demanding bonding and sealing applications. Developed by Risun, this transparent hybrid polymer combines fast curing speed, strong adhesion, and excellent tensile elasticity, making it suitable for structural sealants, industrial adhesives, and transportation sealing systems.
Product Features
  • High transparency with minimal yellowing over time
  • Solvent-free formulation with very low odor during processing
  • Reduced bubble formation during curing, ideal for transparent applications
  • Good adhesion strength and tensile elasticity
  • Excellent resistance to water, yellowing, and long-term aging
  • Fast moisture-curing chemistry with stable processing behavior
  • Compatible with other Risun polymers for customized formulations

Applications
  • Transportation industry sealants
  • Medium construction sealant
  • Eco-friendly decorative sealing products
  • Transparent encapsulate adhesive
  • Eco-friendly decoration sealant and adhesive
  • DIY adhesives
How It Works
350A cures through a moisture-triggered silane reaction mechanism. When exposed to atmospheric moisture, the terminal silane groups hydrolyze to form silanol structures, which then crosslink to create a durable siloxane network. For detailed technical information, please contact our sales department.
