AEROSIL^® Fumed Silica in Adhesives and Sealants

AEROSIL® fumed silica is invented to improve the manufacturing, quality and performance of adhesives and sealants. Due to its specific properties, AEROSIL® fumed silica performs in a multitude of applications in the adhesives and sealants industry. Both hydrophilic and hydrophobic types of AEROSIL® fumed silica, as well as the AEROXIDE® Alu C are mainly used as additives for anti-sag, rheology control and anti-settling in structural adhesives, solvent- and waterbased adhesives. In sealants, AEROSIL® fumed silica is used as rheology control and reinforcing additive while AEROXIDE® TiO₂ P 25 improves the thermal stability. AERODISP® W 7520 is a low viscous, water-based dispersion of AEROSIL® fumed silica which improves shear adhesion and clarity of water-based pressure sensitive adhesives.

AEROSIL^® fumed silica and AEROXIDE^® fumed metal oxides in hot melt adhesives

This Technical Information brochure describes the benefits of fumed silica in hot melt adhesive formulations particularly in styrene block copolymers commonly used in the industry. The brochure offers examples of formulated adhesives and the effects on properties such as adhesion-in-peel, shear time and tack. Choice and loading level of AEROSIL^® fumed silica can modify these properties singly or in conjunction with each other. TI 1323 also offers the example of using AEROXIDE^® TiO₂ P25 to enhance the property of heat stability.

AEROSIL^® Fumed Silica in Waterbased Adhesives & Sealants

This Technical Information brochure describes the benefits of fumed silica in waterborne adhesive and sealant formulations particularly acrylic copolymers and vinyl acetate-ethylene (VAE) copolymers. The literature includes examples of pressure sensitive and construction adhesives, and acrylic translucent (clear) sealant. AERODISP^® fumed silica dispersions and AEROSIL^® fumed silica products improve properties such as cohesive strength, rheology, and specifically for sealants the property of clarity. In addition also the synergy using AEROSIL^® and Dynasylan^® Silanes in waterborne systems is discussed.

Products for 1-component RTV silicone sealant compounds

It is well known that AEROSIL® fumed silica can fine-tune many properties of silicone sealant compounds. It can impart the required rheological and mechanical properties in RTV–1C silicone sealant compounds. In addition to fumed silica, the use of AEROXIDE® fumed oxides and DYNASYLAN® silanes can provide unique properties in RTV–1C silicone sealant compounds. The technical details of these Evonik products developed for RTV–1 silicone sealant compounds will be discussed in this brochure.
