Rheology modification

The Nano sized spheres of SIDISHIELD™ C 25 product allow it to work as “ball bearings” in a filled coating /powder coating. As shear forces are applied, SIDISHIELD C 25 particles will minimize the contact area of solid particlesand, as the spheres are not attached to the matrix, they are able to roll on contact. This leads to a decreased viscosity of the coatings, or the extruder back pressure, when extruding powder coatings. In coatings/powder coatings this effect can be used to fill the entire formulation higher and therefore, in coatings, decrease the VOC content (by higher solids loading). This” ball bearing effect” will also result in better flow of the coatings/powder coatings and, most times, increase the gloss of the final applied films. (Hence this is why our product SIDISHIELD™ C 25 is not recommended as a matting agent).
