Product Information
Powdered rheology additive for polar solvent-based and solvent-free systems to
increase storage duration and sagging resistance.
Application:
• Coatings industry
Special Features and Benefits：GARAMITE-7305 is a rheology additive that delivers advantages over conventional organophilic phyllosilicates (organoclays). Conventional phyllosilicates usually require high shear forces and polar
activators to support dispersion during incorporation. In comparison, GARAMITE-7305 can be incorporated and activated very easily in solvents and binders using moderate shear forces. The additive features a strong pseudoplastic viscosity profile. The use of GARAMITE-7305 allows formulations with high viscosity to be achieved in the low shear range, resulting in excellent anti-settling features and antisyneresis properties. When shear forces are applied, a major reduction in viscosity takes place, which significantly improves the application properties.
• Powder coatings
Incorporation and processing instructions：GARAMITE-7305 is a rheology additive that can be used to increase melt viscosity in powder coatings.Even at low dosage, the melt viscosity is increased during extrusion and cross-linking reaction. The resulting coating will maintain very good flow properties despite its increased viscosity. The combination of different morphological structures in the mineral component results in particularly easy dispersibility with high efficiency. Higher dosages result in a fine texture finish and a reduction in the gloss level. GARAMITE-7305 can be used to modify the surface structure in finely textured systems. The increased melt viscosity improves edge coverage. This results in better corrosion resistance.
• Thermosets
Special features and benefits：GARAMITE-7305 is a solid rheology additive based on a composition of organically modified phyllosilicates. The combination of different morphological structures in the mineral component results in particularly easy dispersibility with high efficiency. GARAMITE-7305 delivers the following advantages over conventional rheology additives in various resins based on unsaturated polyester, vinyl esters,
polyurethanes, acrylates and epoxy resins
• PVC plastisols
Special features and benefits：GARAMITE-7305 is a powdered thixotropic additive based on a composition of organically modified phyllosilicates. It is particularly suitable for the formulation of PVC plastisols. The combination of different morphological structures in the mineral component results in particularly easy dispersibility in the liquid phase.
• Detergents, cleaning and care products
Special features and benefits：GARAMITE-7305 is a powdered rheology additive for medium-polar to high-polar solvent systems that contain aromatic substances, alcohols, glycols, glycerol, esters, ketones, etc. as solvents. It can also be used in nonionic surfactants (alcohol ethoxylates). GARAMITE-7305 is very easy to disperse and can be processed using low shear forces. It does not require an activator to achieve efficacy. GARAMITE-7305
delivers excellent anti-sagging, anti-settling and anti-syneresis properties.
• Non-aqueous drilling fluids
Special features and benefits：GARAMITE-7305 is a special rheology additive that can be used as a suspension agent in all oil-based drilling fluids.
