American Sealants Inc., a Meridian Adhesives Group company based in Fort Wayne, Indiana, has introduced a new fluid applied air barrier, ASI 52AB, designed to provide reliable protection for exterior roofs and walls. This innovative product is aimed at simplifying installation and supporting long-term performance, even in challenging jobsite conditions.
ASI 52AB is formulated with advanced silyl-terminated polyether (STPE) hybrid technology, enabling it to bond to damp or wet substrates without outgassing or bubbling. The material can be applied to surfaces that are not fully dry, making it ideal for use when rain is forecast. Unlike conventional water-based or solvent-based coatings, ASI 52AB is 100% solids and retains its volume as it cures, preventing shrinkage, cracking, and wash-off before cure.
The product offers broad adhesion to common construction substrates, fills fastener holes and surface imperfections, and remains breathable, allowing damp surfaces to dry.
Performance-wise, ASI 52AB stands out with its 500% elongation at break and a service-temperature range of -50°F to 220°F, with intermittent exposure up to 270°F. The material also passed 4,000 hours of QUV testing, demonstrating its UV and weather resistance. With a water-vapor transmission rating of 20 perms at 25 mils, ASI 52AB ensures that damp surfaces can continue to dry. Additionally, the product is low in odor, VOC compliant at 16 grams per liter, and formulated without solvents, phthalates, or isocyanates.
American Sealants Inc. continues to innovate and manufacture high-performance sealants and adhesive solutions for building construction and industrial applications. As part of Meridian Adhesives Group, ASI is dedicated to providing products that are built for real-world conditions. The launch of ASI 52AB Fluid Applied Air Barrier marks a significant advancement in the industry, offering contractors a reliable and versatile solution for air and water protection.
The product is designed to be weather-ready, bonding to damp or wet substrates and resisting moisture exposure before cure. This feature is particularly beneficial in unpredictable weather conditions, ensuring that work can continue even when rain is expected. The 100% solids formulation of ASI 52AB ensures that the material retains its volume as it cures, preventing shrinkage and cracking, which are common issues with conventional coatings.
ASI 52AB's flexible performance is another key feature, with the material delivering 500% elongation at break and a service-temperature range of -50°F to 220°F, with intermittent exposure up to 270°F. This wide temperature range makes it suitable for a variety of climates and applications. The product has also passed 4,000 hours of QUV testing, demonstrating its UV and weather resistance, making it a robust choice for outdoor environments.
In addition to its performance attributes, ASI 52AB is environmentally friendly, with a low odor and VOC compliance at 16 grams per liter. The product is formulated without solvents, phthalates, or isocyanates, making it a safer and more sustainable option for contractors and their projects.
The launch of ASI 52AB Fluid Applied Air Barrier is a significant milestone for American Sealants Inc. and its commitment to providing innovative solutions for the construction industry. The product is expected to simplify installation processes and enhance the durability and protection of exterior surfaces, making it a valuable addition to any contractor's toolkit.
