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

What are the ideal applications of 3M™ Polyurethane Sealant 540?

3M™ Polyurethane Sealant 540 is perfect for sealing and bonding a wide variety of materials, including metal, glass, wood, ceramics, and many plastics.
Is it easy to apply?

Absolutely! The sealant comes in a convenient sausage pack that fits into standard caulking guns for easy dispensing or by hand squeezing.
What benefits does this product provide over other types of sealants available in the market?

3M™ Polyurethane Sealant 540 is known for its ability to maintain permanent flexibility even under extreme weather conditions that provides high tensile strength so as not to break or lead when exposed on harsh environmental conditions such as moisture which ensures consistent performance under different environments. Plus, its non-sag formula allows you to apply it with precision and confidence without worrying about dripping or slumping.

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.
