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.
GENIOSIL® XB is a range of alpha-silane-terminated polyethers of low viscosity and with a high density of crosslinkable silyl groups that produce a close-meshed, three-dimensional network on curing.
New functionalized pigments from the Sachtoperse family of barium sulphate pigments are optimally tailored to their respective binder and designed to provide secure bonding between pigment and resin.
PURALACT® special-grade lactides provide reduced resin viscosity, allowing for coatings formulations with higher solid content, lower VOCs and improved ease-of-use.
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.
This article reports on the performance results of acrylated monomers and oligomers when subjected to typical end-use tests designed to measure the flexibility and adhesion characteristics of coatings.
