Curing temperature and time
WebApr 12, 2005 · The temperature rise depends not only on the illumination time, but also on light intensity, distance of light guide tip from composite resin surface, composition and shade of composite resin and composite thickness. The most commonly used units for polymerization today are halogen curing units, which emit a large spectrum of wavelengths. WebAug 15, 2024 · The best temperature for concrete drying and curing is between 40 and 60 degrees Fahrenheit. If the temperature dips below 40, the drying and curing time will increase exponentially. However, keep in mind that you don’t want the Quikrete to dry and cure too quickly, as this will decrease its integrity, so pouring concrete when it is above …
