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, wea

  • MULTI-PURPOSE BONDING: Forms long lasting seals dissimilar materials such as plastics, fiberglass reinforced plastic (FRP), sheet molding compound (SMC), aluminum, steel, coated metal and wood for increased design flexibility
  • FLEXIBLE BONDS: Maintains elasticity for shock absorption and long-term joint movement
  • PAINTABLE IN MINUTES: Forms a skin in 60-90 minutes 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

PRODUCT FAQ

  1. What is 3M™ Polyurethane Sealant 540?

    3M™ Polyurethane Sealant 540 is a one-component, medium-strength sealant that cures to form a tough, flexible seal.

  2. What color does the sealant come in?

    The sealant comes in gray color.

  3. How much does the cartridge contain and how many cartridges are there per case?

    Each cartridge contains 310 mL of polyurethane sealant. There are twelve cartridges per case.

  4. Can I use this product for sealing windows and doors?

    Yes! It is an excellent adhesive that provides good adhesion to most substrates without priming or abrading. It can be used for sealing or bonding applications when strength retention and elasticity are necessary features of the finished job.

  5. How long does it take to cure completely after application?

    The curing time depends on temperature, humidity level, and other conditions but typically takes between one hour to twenty-four hours.

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 -40°F/-40°C to 194°F/90°C. 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 sealant cartridges and 400ml/600ml sausage packs.
