Eleven compounds designated as colorless and two designated as water-based were evaluated to their suitability for curing of concrete and for their lack of color. All met present requirements for sprayability, drying time, and flash point. Only ten met the moisture- retention requirements. The three that failed the moisture test were one styrene- acrylate resin and both water-based compounds. Infrared analysis revealed that the colorless materials compounds. Infrared analysis revealed that the colorless materials represent 5 different chemical classes 4 chlorinated rubbers 2 modified styrene-butadienes 1 phthalic alkyd 3 carboxylated hydrocarbons and 1 styrene- acrylate. Both water-based materials were identified as sodium silicate liquids. Infrared measurements were used to detect chemical and physical changes of the colorless materials when exposed to laboratory conditions and natural sunlight. Author, modified-PL
