Product overview
CRAYVALLAC® PA4 WDA 12 is a pre-activated amide wax supplied in a mixture of mineral spirit (D60) and alcohols. Under paste form for post addition to solvent-based low polarity coating systems, it provides a very simple and direct mean of introducing shear-thinning rheology with thixotropic viscosity recovery to coating formulations. It is a softer version than CRAYVALLAC® PA3 WDA 20 with enhanced ease of incorporation. It is also a very cost efficient alternative to organoclays. The shear-thinning characteristic provides a very high viscosity under the low shear rates and a low viscosity at the much higher application shear rates. The net result is excellent control of sedimentation combined with ease of application. Immediately following application, the coating’s viscosity undergoes a time dependent recovery as the network re-establishes itself. This time dependence is known as thixotropy and enables the final coating to attain very good levelling.
