Improved performance and mechanical properties of acrylic elastomeric coatings with Exilva

There has been an increased interest in waterbased acrylic elastomeric roof coatings lately. One of the reasons is that they reduce the heat absorption of buildings when compared to the traditional asphalt roofs. In addition to heat prevention and energy savings, acrylic roof coating protects the underlying material from water, UV radiation, chemicals and wear.

Abstract

Improved performance and mechanical properties of an acrylic elastomeric coatings with Exilva

Author: Dr Otto Soidinsalo 

There has been an increased interest in waterbased acrylic elastomeric roof coatings lately. One of the reasons is that they reduce the heat absorption of buildings when compared to the traditional asphalt roofs. In addition to heat prevention and energy savings, acrylic roof coating protects the underlying material from water, UV radiation, chemicals and wear.  

Waterbased acrylic roof coatings are traditionally thickened with cellulosics (HEC) and associative thickeners (HEUR, HASE). The use of these thickeners can often lead to challenges with both water resistance and absorption of the coating. In addition, the control of syneresis and sagging is often challenging.

Exilva microfibrillated cellulose (MFC), a bio-based and multifunctional product made of cellulose is a new alternative to the traditional thickeners. It consists of fibrils with lateral dimensions in the nanoscale and lengths up to micron scale. These strong and rather stiff fibrils are able to form strong films (tensile strength up to 210 MPa). Once Exilva is added to a paint it is usual to see a noticeable effect on the mechanical properties of the final coating. In addition to the effect on mechanical properties, the unique rheological properties allow for an increased stability as well as an easily applicable paint. The high yield stress of Exilva prevents settling of heavy particles as well as floating of hollow microspheres, whereas the strong shear thinning allows the spraying of thick formulations. The superior mud crack resistance allows applying thick layers without any fear of cracking.

Who should attend

This exclusive and free webinar will introduce Exilva, a bio-based and multifunctional product made of cellulose, which is a new alternative to the traditional thickeners. It consists of fibrils with lateral dimensions in the nanoscale and lengths up to micron scale. Everybody who is interested in waterbased acrylic elastomeric roof coatings, is welcome to join.
