3M Polyurethane Sealant 540, Gray, 310 mL Cartridge, 12/Case
- Multi-purpose bonding and long lasting seals
- Permanently elastic to allow joint movement
- 60-90 skin time; paintable, once skin forms
- Good UV resistance
- One component, moisture-curing sealant simplifies production
- Bonds dissimilar materials for increased design flexibility
- Gap filling capability
3M Polyurethane Sealant 540 is an all-purpose, single-component, moisture-curing, gap-filling polyurethane that creates permanently elastic seals and bonds in a wide variety of service environments.
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.
