Highlights
  • HIGH-PERFORMANCE BONDING: Form weather-resistant, malleable bonds between dissimilar materials in vehicular and architectural applications
  • UV RESISTANT: A distinct ability to withstand the sun's rays allows it to excel in challenging outdoor industrial, transportation, and construction environments
  • FLEXIBLE BONDS: Maintains elasticity for design flexibility and long-term joint movement
  • PAINTABLE WHEN WET: This low-VOC sealant forms a skin in 40-60 minutes but can be painted over with water-based paints immediately after application
  • LASTING RESULTS: Silane Modified Polymer (SMP) adhesive sealants provide durable elastomeric bonds that seal against the elements
  • EASY TO USE: Single component, moisture-curing sealant fills gaps and simplifies production

3M Adhesive Sealant 740 UV is a Silane Modified Polymer (SMP) that prioritizes UV resistance, long term durability, and weather resistance. Its ability to fill gaps and bond dissimilar surfaces is ideal for promoting long-lasting bonds and design flexibility. To simplify use in production, this single-component, moisture-curing sealant is paintable when wet, forming skin after 40-60 minutes. SMP sealants such as this are permanently flexible, creating durable, elastomeric bonds that keep moisture out. These innovations paired with excellent UV resistance allow 3M Adhesive Sealant 740 UV to excel in challenging industrial, transportation, and construction applications.
