Siloxane and silicone diluents can reduce the viscosity of epoxy systems as well as lowering surface tension allowing ease of handling, facilitating higher filler loading and infiltration of prepregs and fine structural components. Monofunctional silicone compounds with molecular weights high enough to be considered polymers are sometimes referred to as macromers. Copolymerization of macromers with traditional monomers offers a route to polymers with properties that are usually associated with grafting. Modification of organic polymers with silicon-containing macromers has led to new applications in coatings and pigment vehicles.
