Las burbujas de vidrio 3M K25 son aditivos ideales para aplicaciones de flotabilidad en aguas poco profundas o aplicaciones de procesamiento donde se necesita una alta resistencia. Además, como todas las burbujas de vidrio de 3M, las burbujas K25 son compatibles con resinas termoestables como el poliuretano y el epoxi, y son prácticamente insolubles en agua. Aplicación: Pinturas y revestimientos, caucho y plástico, transporte.

3M™ GLASS BUBBLES  K20 have a density of 0.20 g/cc and an isostatic crush strength of 500 psi. These general purpose spheres have a good strength-to-density ratio and are designed for use in a variety of shallow water (e.g. up to 2,000 feet of sea water) buoyancy applications, as well as emulsion explosives.

Las burbujas de vidrio S28HS son esferas de vidrio huecas con una densidad típica de 0,28 g/cc y una resistencia isostática al aplastamiento de 3.000 psi. Estas burbujas de vidrio están diseñadas para numerosas aplicaciones, como espumas sintácticas en aguas profundas y recubrimientos de pulverización sin aire. Las burbujas producen vacíos fuertes y estables con baja conductividad térmica, lo que ayuda al recubrimiento a lograr la resistencia a la compresión necesaria. Las burbujas de vidrio S28HS ofrecen una muy buena relación resistencia-densidad y un tamaño de partícula pequeño, lo que las hace adecuadas para una variedad de aplicaciones, como la flotabilidad en petróleo y gas, pinturas y recubrimientos rociables sin aire, adhesivos, masillas, selladores, SMC y otros sistemas de resina termoestable.

Stain Resistant Additive and Sealer SRA-451 is a fluorochemical acrylic resin concentrate in ethyl acetate designed for industrial application to porous hard surfaces such as concrete, marble, granite, terracotta, etc. Properly applied, SRA-451 additive imparts excellent and durable water, oil and stain repellent properties as well as dirt pick-up resistance on all types of porous hard surfaces. The substrate’s natural characteristics are generally unaffected by the application of this product. Be sure to evaluate the 3M product for compatibility in your particular application before using.

3M™ W-210  CERAMIC MICROSPHERES are made of alkali alumino silicate ceramic and is one of our smallest high-strength ceramic particles with a typical d90 of 12 microns; it has a controlled particle size distribution. Formulating with these ceramic microspheres allows higher filler loadings while maintaining desired properties such as viscosity control. In addition, these engineered particles are added to many paints and industrial coatings to provide scrub and burnish resistance. Due to their smaller particle size, ceramic microspheres white grade W-210 are typically chosen over other ceramic microspheres for higher gloss formulations. Formulators may be able to extend resin in their formulation by adding 3M ceramic microspheres and potentially reduce cost

Glass Bubbles K15 have a density of 0.15 g/cc and an isostatic crush strength of 300 psi. 3M glass bubbles K15 are ideal for use in a variety of water buoyancy applications, including additives in buoys and moorings. Like all 3M glass bubbles, K15 bubbles are compatible thermoset resins like polyurethane and epoxy, and are virtually insoluble in water.
