Descriptions:"Microfibre Blend 413 is a mixture of short-fibre cotton and colloidal silica. It has largely replaced pure Colloidal Silica and pure Microfibre as thickening agents for WEST SYSTEM liquid resins. Addition of cotton flock has served to substantially reduce the tendency of the colloidal silica to float around in the air and makes the mixing into resin much easier. Furthermore, the colloidal silica serves to offer an added degree of thixotropy to the microfibre, and substantially improves the spreading and working properties of the adhesive mix. Because such small quantities must be added in terms of weight, the effect of WEST SYSTEM 413 on the cured resin properties are negligible, but dispersion of the powderinto the resin must be thorough for optimum results."
