Frontiers Silico-Aluminophosphate and Alkali
The use of phosphate or phosphoric acid as an activator allows the chemical interaction with the aluminosilicates to produce geopolymeric binder with condensed poly (silico-alumino-phosphate) phases (Cao et al. 2005 Liu et al. 2010). Aug 14 2017 · Zinc phosphate pretreatment suffers from limitations on certain substrates including limits on aluminum content and difficulty coating certain high strength steel alloys. The high application temperature and activator step make the customer incur higher operational costs which are mitigated by the use of Group IVB pretreatments.
