ALBIDUR® products consist of a reactive resin in which silicone elastomer particles of a defined size (0.1 – 3 μm) are finely distributed. The silicone elastomer particles have an organic shell structure comprising reactive groups. The toughening mechanism is the same as for reactive liquid rubbers; however, the rubber domains are already preformed and not built during the curing process.
