ABRO foam spray is a multipurpose, expandable polyurethane (PU) foam sealant used for filling, insulating, and sealing gaps, cracks, and holes.

ABRO foam spray is a multipurpose, expandable polyurethane (PU) foam sealant used for filling, insulating, and sealing gaps, cracks, and holes. It provides thermal and acoustic insulation and is used in a variety of indoor and outdoor applications. 
Primary uses
Sealing and insulation: It is commonly used to fill and seal joints, cracks, gaps, and cavities in areas like window and door frames, HVAC systems, and pipes. This helps to lower energy costs by keeping heated or cooled air inside.
Soundproofing: The sealant effectively improves sound insulation for applications on partition walls, screens, and vehicle cabins.
Bonding and mounting: The foam creates a strong bond to common building materials, including lumber, plywood, concrete, and masonry, making it useful for mounting and fixing applications.
Pest control: The cured, hardened foam creates a barrier that keeps out insects, rodents, and other pests.
Waterproofing: Once cured, the foam is waterproof and provides a barrier to moisture. 
Key features:-
1. High expansion: The foam expands to fill large and irregular gaps, crevices, and voids.
2.Durable and resistant: The cured foam is resistant to weathering and is sandable and paintable for a clean, finished appearance.
3.Easy to use: It typically comes with a straw adapter for simple, controlled application. 
Important considerations:-
Safety: Users should wear protective gloves and safety goggles during application.
Surface preparation: For best results, surfaces should be clean and free of dust and grease, though they can be humid.
Proper application: To achieve the desired expansion and curing, the can should be shaken well and applied with the valve facing downward. For larger voids, apply in layers, occasionally misting with water.
