Product Description
3M Polyurethane Glass Adhesive Sealant 590 is a one-component, moisture-curing polyurethane paste for bonding glass, acrylic/PMMA, and polycarbonate windows in vehicle and marine assemblies. It requires no mixing and is applied between 5 and 35 deg C, with primer recommended for window bonding. Typical tack-free time is 25 to 40 minutes at 73 deg F and 50% relative humidity; cure progresses at more than 3.5 mm per 24 hours under those conditions. The cured adhesive has typical tensile strength of 10 MPa by ASTM D412 and Shore A hardness 60 to 65 by ASTM C661.
Key features
- Moisture-cure processing: Typical tack-free time is 25 to 40 minutes at 73 deg F and 50% RH; this is separate from through-thickness cure.
- 10 MPa tensile strength: Typical cured-material tensile strength is measured by ASTM D412; Shore A hardness is 60 to 65 by ASTM C661.
- Primed window bonding: Primer is recommended when bonding glass or plastic windows with this one-component polyurethane.
Applications
Structural windshield installations; PMMA windshields; polycarbonate and acrylic bonding; flush-mounted marine and automotive glass.
