CRAYVALLAC® PA3 BA 20

CRAYVALLAC® PA3 BA 20 is a HAPs-free pre-activated amide wax supplied in a mixture of butyl acetate and alcohol. It is a rheology modifier in paste form with high efficiency (optimum sag resistance and viscosity).CRAYVALLAC® PA3 BA 20 is supplied in the form of crystalline fibres. In a coating system, these fibres form an interacting network. This network gives rise to the shear thinning rheology of the final coating. This shear thinning characteristic provides a very high viscosity under the low shear rates associated with sedimentation, and a low viscosity at the much higher application shear rates. The net result is excellent control of sedimentation combined with ease of application.

Processing Information
  • In order to obtain the maximum efficiency from CRAYVALLAC® PA3 BA 20, it is necessary to disperse this product without destroying the crystalline fibres.
  • It is therefore preferable to incorporate CRAYVALLAC® PA3 BA 20 under low to medium shear conditions over as short a time period as possible.
  • When using a high-speed disperser, it is recommended that CRAYVALLAC® PA3 BA 20 be added during the final stages of production, when the coating has been partially thinned to a viscosity of 600-800 mPa.s (ICI cone and plate at 10000s-1) and the peripheral speed reduced to approximately 4 ms-¹.
  • Too high a speed results in destruction of the active fibres and reduced performance, whereas, too low a speed will result in extended incorporation times.
  • In general, the time required for incorporation should be kept to a minimum in order to minimize damage due to overshear.
