1. Product Overview

Teroson MS 930NA is a one-component, low modulus, flexible adhesive/sealant based on modified silane polymer. It cures with atmospheric moisture to form an elastomeric thermoset, providing excellent adhesion without primer to many substrates. The product is odorless, solvent-free, isocyanate-free, silicone-free, non-corrosive, and sag-resistant with high initial tack. It shows good UV resistance, suitable for both interior and exterior applications. Cure speed can be accelerated with MS 9371B (10:1 ratio).


2. Applications

  • Elastic sealing and bonding across metals, plastics, glass, and painted surfaces

  • Structural and non-structural joints requiring flexibility

  • Interior and exterior use with broad adhesion

  • Avoid use on polyethylene, polypropylene, PTFE, or stressed PMMA/polycarbonate due to cracking risk

  • Not recommended for pure oxygen or strong oxidizing environments
