- Applications
- DeCAL 1000 is recommended for use in flat paints, textured coatings, plasters and woodstains. It is easy to handle and can be incorporated at any manufacturing step.
- DeCAL 1000 is also ideally suited for use in the Industrial, Institutional and Household sectors where its high thickening power, electrolyte tolerance, surfactant stability and water white clarity on neutralization are beneficial.
- DeCAL 1000 is an ideal rheological control additive for water-borne coatings. Use of DeCAL 1000 allows formulation of coatings with an advantageous thixotropic behavior giving non stringy formulations which are easy to apply over a wide range of speeds and or processes. Such formulations are ideally suited for airless spray applications. DeCAL 1000 is effective in the pH range optimally 7.5 - 10.5.
- Since DeCAL 1000 is a synthetically derived product it is less susceptible to microbiological attack than derivatives of cellulose. Consequently the paint formulator can substantially reduce the level of biocide leading to a broader area of application.
- Application Method
- Rheological control additives should preferably be added at the final stage of coating manufacturing, not in the pigment grinding stage as unrecoverable damage to the thixotropic rheology can occur at high shear stress. DeCAL 1000 is convenient to add as a post additive in liquid form thereby, offering flexibility in viscosity adjustment from batch to batch.
- Provided efficient mixing equipment is available DeCAL 1000 can be poured directly into the mix. However it is sometimes easier to add DeCAL 1000 by diluting it 1:1 or even 1:2 with water to avoid shocking the system.
- Should at any time the pH of the final system fall below 7.5 then additional alkali, ammonium or other base is necessary to reactivate the thickening mechanism. Use of volatile alkali (e.g. ammonia) as neutralizing agent improves the water resistance property of the dry film. The amount of DeCAL 1000 required for optimum performance should be determined in trials covering a concentration range.
