Polyurethane Sealants

Product Details:

BOSS® PU 25 is a one-component moisture-curing, polyurethane sealant. It cures into a flexible, durable, and weather-resistant elastomeric sealant that has very good adhesion to most construction and industrial materials. It can accommodate cyclic joint movement of 50% (+/-25%) of the joint width.

Features:

• Can be painted with all water-based paints and other systems.
• Excellent primer-less adhesion on many materials.
• Excellent resistance to many chemicals.
• Good weather and UV resistance.
• High viscosity with permanent elasticity after curing.
• Ideally suited for application in warm and humid climates.

Applications:

• Can be used as a seam sealer for traditional welding or spot welding.
• Bonding of panels, ACP, roofing sheets, and so on.
• Supple bonding and sealing in the automotive industry, especially on surfaces that vibrate – bus-bodies, caravans, and containers.

Feviseal PU Foam is a one-component, moisture-curing polyurethane foam sealant used for filling, sealing, and insulating gaps, cracks, and holes in construction. It provides excellent thermal and acoustic insulation and adheres to most common building materials. Key Features and Specifications Feviseal PU Foam offers excellent thermal and acoustic insulation and adheres to various building materials without a primer. It expands significantly to fill cavities and can be cut, sanded, and painted after about 60 minutes. It has a B3 flammability rating and is typically sold in a 750 ml aerosol can. Common Applications It is used for sealing joints and cracks around doors, windows, and partition walls, as well as for insulating heat and sound. The foam also serves to fill gaps around cables and pipes. Application Instructions For application, ensure surfaces are clean and moist. Shake the can well and apply with the can upside down, filling gaps partially to allow for expansion. The foam becomes tack-free quickly and can be cut within an hour, though full curing takes longer. Cured foam needs to be painted or covered if exposed to sunlight as it is not UV resistant.
