The Advantages of Aerogel aerogel modifies a product's flow properties in accordance with a formulator's exact requirements. increase product viscosity; improve anti-settling properties during storage; control the extrusion properties during application; impart anti-sag properties during cure; act as a reinforcing agent to improve an adhesive's physical properties, especially tear strength. Cabot's Nanogel® state of the art technology can control optical properties, particle size, particle distribution, and porosity during product manufacturing. These process capabilities allow for a unique generation of additives for adhesive and sealant applications. Nanogel® aerogels can be used in a wide-range of adhesive and sealant applications such as highly filled, high viscous thixotropic formulations. high porosity: the highly-porous structure provides high reinforcement at low concentrations flowability: the aerogel beads have excellent flow properties friability: under intense dispersion conditions, the aerogel particles are reduced to sub-micrometer sizes, leading to good reinforcement hydrophobic surface: the particles repel water but can be wetted by oleophilic substances such as oils open porosity: the pores of the aerogel are open to each other particle size: the products are available in a wide range of particle sizes surface treatment: the surface groups are chemically anchored to the silica skeleton, and are stable over a wide range of temperatures and pH stronger adhesion higher transparency lower concentration of aerogels required as compared with conventional silicas faster recovery time less sag better viscosity stability decreased rest tack after curing increased shore hardness less bleeding smooth surface appearance The Nanogel ® Aerogel IR Opacified Beads are pale brown,free flowing,spherical particles.The size distribution of beads is narrow and centered around 1mm.The beads additionally contain fine particles of titanium dioxide, which make them attractive in insulation applications when radiative heat transfer has to be minimized.The pore volume exceeds 90%. It is this high porosity,in conjunction with the associated fine structure of aerogel and the presence of titanium dioxide additive that insures exceptional thermal performance in a variety of applications. The nanoporous structure of the aerogels hinder the transfer of heat by reducing the collision frequency of the gas phase molecules. The skeleton of the aerogel is made of amorphous silica. Opacifiers such as titanium dioxide ((rutile)or carbon black can be incorporated into the areogel production process to reduce radiative heat transfer in applications. Pale brown, free flowing, spherical particles, amourphous. Contains fine particles of titanium dioxide to provide very good thermal performance in a variety of applications. Used as a reinforcing agent in adhesive and sealant products, such as epoxies, pressure sensitive adhesives, acrylics, polyurethanes, and cyanoacrylates. Controls optical properties, particle size, particle distribution and porosity during product manufacturing. Suits for highly filled, high viscous thixotropic formulations. Provides high reinforcement at low concentrations, flowability, friability, open porosity and stability over a wide range of temperatures and pH. Gives stronger adhesion, higher transparency, lower concentration, faster recovery time, less sag, better viscosity stability, decreased rest tack after curing, increased shore hardness, less bleeding and smooth surface appearance.
