Barreiras de Ar, Água e Vapor

Protecting buildings from air, water and vapor with compatible barrier applications

Meet the installation and performance needs of modern building construction with liquid barriers that protect from air, water and vapor. Liquid barrier applications – such as acrylic emulsion polymers and water-based silicone technologies – can help you build an even better barrier and protect the building envelope. Whether meeting regulatory requirements for energy efficiency or enhancing weatherability, Dow barriers meet the need for high-performance building design. Key benefits of air, water and vapor barriers include:

• Airtight performance in a wide range of temperatures
• UV-resistant technology and advanced weatherproofing
• Long-lasting, primerless adhesion to challenging materials, including PVC and metals
• Durability 
• Low-VOC formulation
• Bulk water resistance and covers a wide range of vapor permeabilities
