SEAL 'N' FLEX^® CONSTRUCTION H361

Bostik Seal 'N' Flex^® Construction H361 is a one-component, moisture-curing construction sealant based on silane-modified polymer (MS Polymer) technology. It delivers excellent flexibility, strong adhesion to a wide range of substrates, and long-term durability, making it a reliable choice for sealing and bonding joints exposed to movement, vibration and weather.
Suitable for indoor and outdoor construction applications, it is designed to handle joints that face ongoing movement and vibration without losing adhesion, making it a dependable, all-round sealant for general construction, façade detailing and roofing work.

Why choose Seal 'N' Flex^® Construction H361?
Its formulation cures with atmospheric moisture to form a flexible, durable seal that keeps working as joints move and flex over time. It bonds strongly to a wide range of substrates, giving one product broad coverage across a typical job site, and holds up under weather and vibration exposure for long-term performance both indoors and outdoors.

Where to use it
Seal 'N' Flex^® Construction H361 can be used with stone, brick, concrete and glass, plasterboard, solid plastics (except polyethylene, polypropylene and fluoroplastics), ceramics, aluminium and other metals, composites, stainless steel and wood.
