• CRAYVALLAC® LV is ideally incorporated and activated using a high-speed disperser.
• The use of high-speed dispersers is ideal in that they generate both the necessary and temperature required for full dispersion and activation.
• CRAYVALLAC® LV is best added along with the initial charge of resin during the pigment dispersion and grind stage.
• Efficient activation will be achieved by allowing the temperature during this dispersion process to rise to 50 - 65°C (122 - 149°F), but more preferably from 60 - 65°C (140 - 149°F).
• This condition of dispersion and temperature control should be maintained for 20 - 30 minutes to ensure full activation.
• The activation process constitutes the conversion of CRAYVALLAC® LV particles to an interacting network of crystalline fibres.
• It is this network that gives rise to the final coating’s shear thinning rheology.
• 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 shear rates.
• The net result is excellent control of sedimentation combined with ease of application.

• It should be stored in the original containers in a dry place at temperatures between 5°C (41°F) and 30°C (86°F).
• Avoid exposure to direct sunlight or frost. In these conditions, this product should be used within 48 months from production.
