- PAINTABLE IN MINUTES – Forms a skin in 60-90 min that can be painted on once the sealant is fully cured
- Weather Resistant – A distinct ability to excel in challenging outdoor industrial, transportation, and construction environments between -40 F (-40 C) and 194 F (90 C)
- EASY TO USE – Single component, moisture-curing sealant fills gaps and simplifies production
3M™ Polyurethane Adhesive Sealant 540 is a moisture-curing sealant that forms flexible, weather-resistant bonds. This single-component adhesive bonds dissimilar materials including plastics, sheet molding compound, aluminum, steel, coated metal, and wood in temperatures ranging from 40 °F (40 °C) to 194 °F (90 °C). Polyurethane sealants perform well in challenging industrial, transportation, and construction settings by creating durable elastomeric bonds that seal against the elements. High tensile strength, weather-resistance, and low hardness allow 3M™ Polyurethane Adhesive Sealant 540 to excel in applications such as exterior panel bonding, retail storefronts, and transportation manufacturing.
