Materials latex

Of the several types of the polymer-modified mortars and concretes used for various construction applications, latex-modified mortar and concrete are by far the most widely used materials. Latex-modified mortar and concrete are prepared by mixing a latex, either in a dispersed liquid or as a redispersible powder form with fresh cement mortar and concrete mixtures. The polymers are usually added to the mixing water just as other chemical admixtures, at a dosage of 5-20% by weight of cement. Polymer latexes are stable dispersions of very small (0.05-5 pm in diameter) polymer particles in water and are produced by emulsion polymerization. Natural rubber latex and epoxy latex are exceptions in that the former is tapped from rubber trees and the latter is produced by emulsifying an epoxy resin in water by the use of surfactants [87].

The latex compounding technique represents an alternative approach to the preparation of blend materials. Latex compounding is a promising method when compared, for example, to the in-situ polymerization and solution techniques that are used to produce polymer blends. Today, the procedure is becoming increasingly important as many simple polymers are available in latex form, and latex can be introduced into the polymer melt during compounding in line. In an... 

DOWICIL 75 Preservative is the designation for l-(3-chloro-allyl)-3,5,7-triaza-l-azoniaadamantane chloride combined with a stabilizer (sodium bicarbonate). It is designed to provide highly effective anti-microbial activity in aqueous formulations, including adhesives, paints, construction materials, latexes, and detergents, to name just a few.
