tetra-methyl-ortho-silicate-coupsyl-tmos Tetra methyl ortho silicate (TMOS) is a colorless, flammable, and highly toxic liquid from the alkoxy silane family. It has low viscosity, a pungent odor, and hydrolyzes with moisture to produce SiO₂ and methanol. As a silane coupling agent, it dissolves in alcohols and common solvents and is the main, most widely used, and […]

Concrete Acid Stain COUPCOLOR® CAS Concrete acid stains create color by reacting chemically with the calcium in concrete rather than using pigments. Because the color results from this reaction, they are not true paints. The final color varies depending on the concrete’s type, quality, and cement content — higher-grade concrete yields deeper, richer tones. Ask […]

Acid stain neutralizing powder – COUPCOLOR® ANP COUPCOLOR® ANP is a white powder used to neutralize unreacted acid stains on cement and concrete surfaces after painting. It should be mixed with water at a 1:25 ratio and sprayed on the stained surface after the acid stain has had enough time to react. Ask for Pricing […]
