Thixotropic agent

Examples of thixotropic agents include fumed silicas and treated clays. These inert pigments are sometimes added to aid in film build, to add body to a paint, or for antisettling characteristics [2],

Mention may also be made of an application in which careful control of polymer morphology has led to the production of novel materials. By treatment of solutions of high-density polyethylene, products are obtained with a celluloselike morphology and which are known as, fibrides or synthetic wood pulp. They are used for finishing paper and special boards to impart such features as sealability and improved wet strength. They are also reported to be used for such diverse applications as tile adhesives, thixotropic agents, battery separators and teabags ... 

The peroxides and accelerator should not be brought into contact with each other as they form an explosive mixture. When the resin is to be used, first the accelerator and then the peroxide are carefully dispersed into the resin, which may also contain inert fillers and thixotropic agents.

Thixotropic agents Thixotropic agents impart thixotropy to the adhesive to control flow and increase viscosity. 

Thickeners, fillers, and thixotropic agents are also commonly used to control flow and the bond line s thickness within a joint. Scrims, carriers, and woven reinforcements are other methods commonly used to control bond line thickness. 

Fumed Silica. Today colloidal silica (fumed silica) is the most common thixotropic agent in epoxy resins. Fumed silica, an amorphous silicon dioxide, is a versatile, efficient additive used for flow control and thixotropy. Fumed silica has long been the dominant thixotrope employed in the adhesive and sealant industry.

This process also called just bag molding. It is the conventional hand lay-up or spray-up that is allowed to cure without the use of external pressure. For many applications this is sufficient, but maximum consolidation may not be reached. There can be some porosity fibers may not fit closely into internal corners with sharp radii but tend to spring back. Resin-rich and/or resin-starved areas may occur because of draining, even with thixotropic agents. With moderate pressure (hand rollers, etc.) these defects or limitations can be overcome with significant improvement in mechanical properties. 

Puffing agents, or thixotropic agents, increase the paint consistency and minimize sagging by giving a thixotropic consistency to paint (a type of behavior in which the viscosity of the system decreases when agitated, as under the shear of brushing, and increases when allowed to stand). 

Type B. Anaerobic adhesive containing Type A with thixotropic agents, inorganic fillers and rubbers. 

Note Type of monomer used can vary from basic ethylene glycol mono- or di-methacrylates to complex structures that are beyond the scope of this book. Type of stabilisers, initiators, promoters, colorants, fillers, rubbers and thixotropic agents are propriety to adhesive manufacturing companies.
