Le bolle di vetro 3M K25 sono additivi ideali per applicazioni di galleggiamento in acque poco profonde o applicazioni di lavorazione in cui è necessaria un'elevata resistenza. Inoltre, come tutte le bolle di vetro 3M, le bolle K25 sono compatibili con resine termoindurenti come il poliuretano e la resina epossidica e sono praticamente insolubili in acqua. Applicazione: vernici e rivestimenti, gomma e plastica, trasporti.

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.

Le Glass Bubbles S28HS sono sfere di vetro cave con una densità tipica di 0,28 g/cc e una resistenza allo schiacciamento isostatico di 3.000 psi. Queste bolle di vetro sono progettate per numerose applicazioni, come schiume sintattiche in acque profonde e rivestimenti spray airless. Le bolle producono vuoti forti e stabili con bassa conduttività termica, aiutando il rivestimento a raggiungere la necessaria resistenza alla compressione. Le bolle di vetro S28HS offrono un ottimo rapporto resistenza/densità e una piccola dimensione delle particelle, che le rendono adatte a una varietà di applicazioni come la galleggiabilità in petrolio e gas, vernici e rivestimenti spruzzabili airless, adesivi, mastici, sigillanti, SMC e altri sistemi di resine termoindurenti.

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.
