of the ptfe had been completed 30 g of a mica based pigment was added followed by 11 8 g of alphasan rc2000 a zirconium phosphate coatings were sprayed on previously dried sol gel layers applied on anodized aluminum plates and cured at 300 u00b0 c the amount of alphasan rc2000 particles in the cured coating was approximately 1 5 by volume the amount of ag was approximately 0 04 by volume in a reaction vessel 5 5 g of maleic acid was dissolved in 380 g of ludoxas40 an amount of 0 95 g of mtms was then added and the mixture was stirred for 45 minutes subsequently 391 g of mtms was stirred into the acidified silica sol 60 minutes later the mixture was diluted with 196 g of water before the gradual addition of 315 g of 30 ptfe dispersion in water stabilized with sil wet l77 together with a suitable defoaming agent after the addition of the ptfe had been completed 30 g of a mica based pigment was added followed by 3 0 g of alphasan rc2000 a zirconium phosphate coatings were sprayed on previously dried sol gel layers applied on anodized aluminum plates and cured at 300 u00b0 c the amount of alphasan rc2000 particles in the cured coating was approximately 0 37 by volume the amount of ag was approximately 0 01 by volume in a reaction vessel 5 5 g of maleic acid was dissolved in 380 g of ludoxas40 an amount of 0 95 g of.
