It is also recommended in top coat and direct to metal application for its smoother viscosity resulting in good compromise between levelling and sag resistance. It imparts shear thinning rheology with thixotropic viscosity recovery. The net result is excellent control of sedimentation combined with ease of application. view less | Request Sample |
