Summary of System I – 2K Heat Cured SB/PU coating system
1. The samples prepared with FA 3ACR and FA 1 have some fisheyes, indicating incompatibility. Defects from FA 1, with its
highest CF2 content, are not surprising. But FA 3 ACR causing defects, especially since FA 3 was defect free, is surprising.
2. FA 3, FA 2 and both FPE fluoroalkyl silicones give smooth appearance with 2K SB/PU coating system.
3. The gloss of FPE 1 and FPE 2 samples remains unchanged over the control indicating that these are the most compatible species used.
4. The coatings prepared with fluoroalkyl silicones all had reduced COFs and increased mar resistance. The surprisingly poor
performance of FA 1, FA 2 and FA 3 could be explained by their reacting into the PU film which we have shown affects this
property.2
5. Stain performance is improved over the controls, but are similar in all additives. This property seems more dependent on
stain than type additive.
