ASHLAND SPECIALTY INGREDIENTS launched Natrosol™ Performax hydroxyethylcellulose, a paint-thickening technology that accelerates production and increases quality of waterborne architectural coatings.
In Part 1 of this article series,1 we discussed a new class of reactive surfactants, both nonionic and anionic, for use in both conventional aqueous emulsion polymers and in UV-curable coatings that contain two polymerizable moieties.
Although silicone-modified polyester (SMP) and super-polyester coatings are well-suited for specific applications, they cannot provide the same proven long-term performance as 70% polyvinylidene (PVDF) coatings due to the latter’s superior chemistry.
First, it was adhesion to multiple substrates, then the requests were for better dirt pick-up resistance. Now, contractors are asking for – and receiving – an elastomeric roof coating that has the potential to resist hard rain much faster than previous technologies enabled.
In this article, we evaluate how silicone additives can be used beyond the traditional benefits, and demonstrate how these additives can bring added performance in titanium dioxide-based formulations to prevent this age-old problem.
