Butyl sealants are reliable materials used wherever durability, flexibility, and resistance to weather conditions are essential. Thanks to their unique properties, they have found wide application in construction, industry, and automotive sectors. Importantly, they are available in various forms, tailored to specific needs. Find out what forms butyl sealants come in and where they are most effectively used.
Butyl Sealant – Available Market Forms
1. Butyl Sealant Paste (in cartridge or bucket)
The most common form – a flexible paste packed in standard cartridges (for caulking guns) or larger industrial containers. Ready to use, it remains soft and doesn’t run or harden, making it ideal for precise sealing.
Applications:
-
Expansion joints and structural connections
-
Sealing around windows and doors
-
HVAC and ventilation joints
2. Butyl Tape (self-adhesive)
A highly practical form – flexible tape with one side coated in butyl adhesive. Frequently used in roofing, flashing, and membrane installations.
Applications:
-
Roof and window joints
-
Sealing between sheet metal elements
-
Installation of vapor and wind barriers
3. Butyl Rope (profiled cord)
A soft, flexible butyl cord, often used in sealing precast concrete elements, insulated glass units, and automotive components.
Applications:
-
Precast concrete elements (walls, tanks, manhole rings)
-
Insulated glazing units
-
Automotive industry (e.g., headlights, door seals)
4. Butyl Sheets or Mats
A less common form – thin, flexible sheets coated with butyl, used as moisture or sound barriers.
Applications:
-
Industrial insulation
-
Sound-deadening mats in vehicles
-
Protection against moisture and corrosion
