RHEOBYK® -7690

RHEOBYK® -7690 by BYK is a solid, non-dusting, biocide-, VOC-, APEO-, and tin-free associative thickener (HEUR) for aqueous systems that generates a newtonian flow behavior. It has only a low impact on the low shear range and improves or increases the brush resistance. It reduces spattering during application.

• Higher film thicknesses can be achieved along with an excellent balance between the flowability and leveling.
• Combining it with rheology additives that are effective in the low shear range, such as RHEOBYK®-7650, leads to optimized storage stability and processability.
• It has no negative effect on gloss or color acceptance.
• It is recommended for emulsion paints, architectural coatings, wood & furniture coatings, industrial coatings, marine-, protective coatings and floor coatings.
• Recommended dosage level is 0.2-0.8% based on the total formulation.
• RHEOBYK® -7690 has shelf life of 36 months.
