Flat-Ayd® Pre-Dispersed Flatting Bases
For Gloss Control of Coatings
Flat-Ayd Bases are dispersions of selected flatting agents in a variety of vehicles. 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.)
Dispersion of silica flatting agent in medium-oil alkyd vehicle for gloss control of coatings. Can be used in alkyd-compatible vehicles, in bake finishes and acquers. Provides simple stir-in incorporation, efficient gloss reduction and assured reproduction of results. Contains polyolefin and also provides a high degree of scuff and polish resistance. Coatings utilizing it produces films of excellent clarity and sheen uniformity.
