Geon 213 Blending resin Polyone Rheology Modifiers / Thickeners SEALANT ADHESIVE SEALANT >> Plastisol The Geon 210 Series of blending resins offers the formulation chemist a variety of tools in controlling the viscosity, viscosity aging and surface characteristics of plastisols. Blending resins are utilized as a one for one replacement of the dispersion resin contained in the plastisol formulation, at a typical loading of 20 to 30 phr. The larger particle size of blending resins compared to dispersion resins prevents blending resins or dispersion resins from use in very thin gauge applications. Geon 213 Recommended in thinner coating application Blending resins, also known as extender resins, are used as a formulating tool in the development and production of plastisols. These products are primarily used to decrease viscosity (both Brookfield Viscosity and Severs Viscosity) and improve viscosity aging stability. However, blending resins are also used to reduce the gloss and surface blocking of films and parts. Typical blending resins have an average particle size of 20 to 50 microns, although a wide array of particle size resins can be used to successfully produce plastisols. The coarser nature of blending resins allows for better powder flow characteristics and the opportunity for customers to successfully bulk handle these products. However, as a general rule, blending resins should not be used in applications thinner than twice the average particle size of the blending resin used in the plastisol. Typical usage of blending resins is 20 to 30 phr, as a replacement for an equivalent amount of dispersion resins. Generally, blending resin usage does not exceed 40 phr. High levels of blending resin, especially at low Brookfield Viscosities, may result in resin settling issues. Blending resin. Used in adhesives and seals.
