- Usage
The minimum film forming temperature of the Styacryl A120 will be reduced by adding sufficient amounts of coalescing agents (and in some cases also plasticizers) which must be done with due care. Water miscible solvents like propylene glycol improve the frost resistance. The usual titanium dioxide and colored pigments as well as fillers or extenders may be used for the formulation of the coating systems. Depending on the nature of the pigments and extenders, the required quantity is in range between 0.1 and 0.4 % active substance of dispersing agent relative to the pigment/extender mixture. Many thickeners are usable to adjust the desired viscosity of the coatings. Many commercially available defoamers can be included in order to prevent excessive foaming in the paints. Trials must be carried out to determine the most suitable grades and the correct concentration.

Safety & Health
- Product Safety and Environmental Protection
The usual protective measures employed during the handling of aqueous polymer emulsions should be observed.
Storage & Handling
- Preservation and Storage
The dispersion contains some initial preservatives to prevent attack by microorganisms. In order that the product is also sufficiently protected against microbial contamination during further storage in opened drums, tanks or other storage facilities a suitable preservative should be added despite our preliminary preservation measures and the tanks and pipe work should be kept adequately clean. Styacryl A120 has minimum shelf life of 6 months from the dispatch date, provided the product is at temperatures between 5 °C and 30 ° C, avoiding frost and direct sunlight. Furthermore, it must be ensured that already opened drums and containers are always tightly closed. For bulk storage, additional conditions like the addition of preservatives or frequent stirring are technically applicable and recommended. To remove any skins or lumps that could have been formed during longer storage of the dispersion due to its film forming nature a filtration or sieve process is recommendable before further processing. The technical data ascertained by our quality control laboratory at the time of product release may vary according to the storage time and storage conditions and may deviate from the original values.
