Epoxy Temperature – What are the best conditions to use CHILL EPOXY™

The temperature must be the closest to 22°C/72F.  Remem 

Temperature 

As you know and based on your geographical location or winter is the cold might affect the curing time of your thermoset CHILL EPOXY™ products. 

 Before going any further, let me give you the definition of a “THERMOSEL RESIN”: 

 A thermosetting resin, often called a thermoset, is a polymer that is irreversibly hardened by curing from a viscous liquid prepolymer or resin. Curing is induced by heat (exotherm) when mixing resin (part A) to a hardener (B). 

I put emphasis here on CURING IS INDUCED BY HEAT (EXOTHERM).   

 This means that if the natural reaction of the mixed parts A and B is reduced by cold, the exotherm level will directly be reduced as well. If it occurs, the set time (polymerization) will take longer because there is less energy for the molecules to link to itself by a covalent link.  

 So, the colder the temperature is in the pouring environment, the longer time the resin takes to fully cured, as simple as that. 

Cold also has an incidence on the viscosity of the resin.  The colder it is, the higher the viscosity will be.  

Keep also in mind that if you work in a cold environment less that 22°C the curing process will be slowed down.  Every 1°C less than 22°C will slow down the curing process by an approximate 10%, so do not minimize this important factor when using our CHILL EPOXY™ products.
