3M™ Polyurethane Glass Adhesive Sealant 590 is a one-part, high viscosity polyurethane sealant for bonding windshields and other glass, acrylic, polycarbonate and many other materials. This high strength adhesive stays flexible after cure, resulting in a durable, long-lasting bond that helps joints or bonded areas resist vibration fatigue.

Suitable for Structural Glass Bonding; Crash Tested to FMVSS 212
3M™ Polyurethane Glass Adhesive Sealant 590 is specifically formulated for the unique characteristics and requirements of structural glass bonding and vehicle window glazing. Strong yet flexible, our crack resistant adhesive sealant offers reliable bonding that expands and contracts with heat and cold.
Recommended Applications

Structural windshield installations
PMMA windshield applications
Hard-to-bond polycarbonates and acrylics
Flush-mounted glass for both marine and automotive use

Understanding Polyurethane Sealants
Polyurethane sealants provide strong, flexible durable elastomeric bonds that seal against the elements. These sealants excel in challenging industrial, transportation and construction applications. Polyurethane sealants are available in a wide variety of Shore A hardness, open time and colors to meet many application needs. Choose a 3M Manual or Pneumatic Applicator for dispensing 3M adhesives sealant cartridges and 400ml/600ml sausage packs.
