LAVIOTHIX and LAVIOKOLL is a range of clay-based rheological additives suitable for water-borne coatings and construction systems: these products are inorganic, based on a selected, purified and activated clay with a very high montmorillonite content and a high specific surface area. They provide enhanced thickening, thixotropic and antisettling properties, preventing sedimentation of suspended particles; also sag control and storage stability are increased.
LAVIOTHIX and LAVIOKOLL range are suitable for use in all mineral-based systems as mortars, plasters, tile adhesives, renders. They are also suitable for different waterbased coating systems.
In construction systems such as mortars, renderings, stuccos, flooring systems and building adhesives, flow control is very important and the main additive used to provide thickening and water retention is cellulose ether. However, the system performance and application behaviour can be significantly improved by using clay based thickeners in combination with cellulose ethers.
Features and Benefits
- LUBRICANT EFFECT: the clay platelets, slipping one on the other, can reduce stickiness on tools caused by cellulose ethers or redispersion powders and also improve the application behaviour concerning the surface quality and application speed
- ANTI-SAGGING EFFECT: thanks to its yield point (the minimum shear stress applied to a system to induce flow ) bentonite clay builds a network with a high yield value which can improve sag and slump resistance and controls settling and bleeding
- ANTI-SETTLING EFFECT: bentonite clays are used as a stabilizer to prevent settling of coarse particles and reduce bleeding of water on the surface, leading to smoother finishes
- WORKABILITY IMPROVEMENT: the clay network breaks down when a shear is applied to the system (pumping, mixing, tooling), and the resulting viscosity is lower than that from cellulose ethers, improving the workability
