Formulation for a Marble and Terrazzo Polish

A typical formulation for a marble and terrazzo polish is given below. 

Add premix 1 slowly to the premix 2, with good stirring. Then add FC-134 (levelling agent, 3M) and defoamer, such as SE-2/H20 1/9 from Wacker, and stir well for at least 30 minutes. This formulation can be used as an exterior coating, having extreme water and moisture resistance. 

NeoCiyl A-1049-U is an anionic aciylic dispersion, 40 %nvc with a MFFT of 40 C. NeoCiyl BT-21 is an acrylic dispersion, 40 %nvc. Sudranol 100 is a wax emulsion to improve water repellency. Steinapol SBDO-70 (Rewo) can be used as the wetting ad tive. For good film formation, a combination of coalescents and plasticisers are added. 

Concrete flooring is often used in areas which have unusually heavy traffic. General requirements in such coatings (including other floors, such as wooden) are  

Silica can be added as extender to increase wet abrasion resistance. Small amounts of aluminium oxide can also be used instead of silica with little effect on sheen. Because of the abrasive nature of aluminium oxide, it should be added at the end of the let down stage with just sufficient stirring for good wetting and dispersing. Pine oil may be used as plasticiser for improved odour characteristics. Epoxy ester emulsions, such as Araldite DP-624 (Ciba), may be added to improve resistance to cracking and lifting of the film under severe exterior conditions.
