A new advanced modified polymer sealants line combines the best attributes of traditional silicones and polyurethanes, enabling construction professionals and do-it-yourselfers to benefit from a sealant that offers superior weatherability and durability.

Sealants and adhesives play an integral role in the building envelope. However, not all adhesive formulations are created in the same way or from the same materials. Some may actually interact negatively with various building materials or perform temperamentally in areas of the country that experience broader seasonal temperature fluctuations. Choosing the correct adhesive saves valuable time and reduces labor, as well as the likelihood of costly rework.

Despite all the discussion and debate in society over reducing our waste and carbon footprint, sausage packages (also known as chubs) for adhesives and sealants continue to gain little support in the building industry—even though their reduced packaging and low waste factor represent a step change in sustainability.

Hybrid sealants are best defined as a fusion of technologies: the best performance properties of urethanes combined with the best of silicones.

A recent study finds that naphthenic oils can offer a viable alternative to silicones in construction sealants. A newly developed range of specialty oils also provides formulators with the right balance between viscosity, color stability, and volatility.
