- Fast Skin-Over Processing
- Elastic Structural Bonding
Product Description
TEROSON® MS 5570™ is a one-component, moisture-curing modified silane polymer adhesive and sealant for elastic bonding and sealing across a variety of substrates. The white paste cures through exposure to atmospheric moisture to form an elastomeric thermoset material. It combines high strength, high elongation, high initial tack, sag resistance, good UV resistance, and compatibility with suitable paint systems for interior and exterior applications.
Key features
- Elastic bonding and sealing: Provides a high-strength, flexible bond with 230% elongation at break.
- One-component moisture cure: Requires no mixing, develops functional strength in approximately 24 hours, and fully cures in about seven days under normal conditions.
- Broad application performance: Offers high initial tack, sag resistance, good UV resistance, and compatibility with suitable paint systems.
