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.

Multi Purpose Sealant with Good UV Resistance
3M Polyurethane Sealant 540 is a single component, moisture curing, polyurethane sealant used to bond a wide variety of materials, including plastics, fiberglass reinforced plastic (FRP), sheet molding compound (SMC), aluminum, steel, coated metal and wood. It exhibits high tensile strength, good UV resistance, low Shore A hardness and low modulus to maintain its functionality in a wide range of extreme service environments. Available in cartridge, sausage pack, pail and drum volumes to meet your application needs.

Recommended Applications

  • Vertical and horizontal panel bonding and joint sealing
  • Aluminum curtain walls and storefronts
  • Transportation manufacturing (bus, rail, truck, trailer)
  • Replacement of mechanical fasteners in many situations

Paintable after Skin Forms for Improved Appearance
3M Polyurethane Sealant 540 offers an alternative to mechanical fasteners and can replace rivets in some applications. It will bond dissimilar substrates and a wide selection of materials. This will perform in temperatures ranging from 40F/ 40C to 194F/90C. Once skin forms (60 90 minutes), the sealant can be painted to improve the final finish.

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.
