Product Description
Polyurethane Sealant 540
- EASY TO USE: Single component, moisture-curing sealant fills gaps and simplifies production
- FLEXIBLE BONDS: Maintains elasticity for shock absorption and long-term joint movement
- 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
- 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)”
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 adhesives sealant cartridges and 400ml/600ml sausage packs. Bringing Better Ideas to the Surface through Science and Innovation In the 3M Industrial Adhesives and Tapes Division, 3M apply the science of adhesion to deliver innovative solutions that improve the design and manufacturing processes of companies around the world. In the end, the technologies help customers like you deliver competitive products to the market faster and more efficiently.
