3M Polyurethane Adhesive Sealant 550 Fast Cure
What It Is
Polyurethane Adhesive Sealant 550 Fast Cure refers to a one-component, moisture-curing polyurethane adhesive-sealant — most commonly made by 3M as part of its 500 Series. It combines the functions of both an adhesive and a sealant: forming strong, flexible, weather-resistant bonds between various materials.
Key Properties
- One-component, moisture-curing — cures simply by exposure to moisture (no mixing needed).
- Fast-cure formulation — forms a paintable skin in about 60–90 minutes, which helps speed up project timelines.
- Elastomeric (flexible) — stays somewhat elastic after curing, which helps absorb stresses from vibration, thermal expansion, and movement.
- Temperature-resistant — bonds hold across a wide working range (approx. −40 °F to 194 °F / −40 °C to 90 °C).
- Paintable after curing — you can repaint over the sealant once it’s skinned over.
