TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Composition: The dispersion comprises up to 30 wt.% of water and additionally, as primer, a polysiloxane compound of formula ((CH3)3SiO((CH3)R5SiO)nSi(CH3)3) (III) or (cyclo-((CH3)R5SiO)p) (IV).R5 = randomly distributed CH3 or 6-24C hydrocarbon, where at least one of R5 is not methyl;n = 1-100; andp = 3-100.Preferred Components: The hydrophobic silicic acid exhibits a weight average median value of particle size distribution of 50-800 (preferably 50-200) nm. Preferred Method: The dispersion is applied on the surface by wiping with a cloth or sponge, painting with a brush, or rolling with an applicator roll. The surface is immersed in the dispersion and excess dispersion is drained.    TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The carboxyvinyl polymer is neutralized with alkanolamine (preferably tetrahydroxy propylethylene diamine). The carboxyvinyl polymer is a copolymer that, as monomer units, comprises acrylic acid and/or methacrylic acid and an ester of acrylic acid and/or methacrylic acid with 1-4C alcohol or a crosslinked copolymer that, as monomer units, comprises acrylic acid and/or methacrylic acid and an ester of acrylic acid and/or methacrylic acid with 10-30C alcohol. The polysiloxane has an average molecular weight of less than 10000 (preferably less than 1000) g/mole. EXAMPLE - Aerosil R 812 S (RTM: Hydrophobic fumed silicic acid) (200 g) was added to a solution of hexamethyl disilazane (2 g) in ethanol (798 g) under stirring and dispersed for 15 minutes at 2200 minute-1 using Dispermat (RTM: High speed laboratory dissolver). The obtained suspension was ground in a wet jet mill having jet velocity of 700 m/second and worked up to give a suspension-1. The obtained suspension-1 was diluted with further ethanol (332 g). Tego Carbomer 341 ER (RTM: Acrylates/10-30C alkyl acrylate crosspolymer) (10 g) was added into water (365 g) and evenly suspended. A mixture of tetrahydroxypropyl ethylene diamine (12.5 g) and ethanol (112.5 g) was added under stirring to obtain a concentrated and clear aqueous solution of neutralized carboxyvinyl polymer having pH value of 7. The aqueous solution (2.5 g) of neutralized carboxyvinyl polymer was added to a mixture of water (86.5 g) and ethanol (1 g) under stirring. The obtained clear viscous solution was added under stirring to the suspension-1 to obtain a viscous dispersion.
