They provide simple stir-in incorporation, efficient gloss reduction and assured reproduction of results. Those Flat-Ayd Bases containing polyolefin also provide a high degree of scuff and polish resistance. Coatings utilizing Flat-Ayd Bases produce films of excellent clarity and sheen uniformity. Compatibility and Effectiveness The gloss of a coating can be reduced to any desired level by adding a sufficient amount of the appropriate Flat-Ayd Base. The effectiveness of any flatting agent always depends on the nature of the main film former. In general, the greatest effect is obtained with coatings of low film build that are based on fast setting vehicles of low inherent gloss. In most applications 5% to 15% Flat-Ayd will reduce 60° gloss by 40 to 60 units. All Flat-Ayd Bases contain sufficient suspending agent to prevent hard settling. If separation of silica takes place on prolonged storage, the sediment will be soft and easy to redisperse, except in cases of excessive dilution or vehicle incompatibility. Incorporation Techniques To assure smooth, speck-free finishes, Flat-Ayd Bases should be diluted with 5% to 10% solvent while under moderate agitation. The diluted Flat-Ayd should then be slowly added to the coating under continued agitation. (Caution: Excessive mixing at high shear may cause loss of efficiency.)
