REASONS WHY YOUR EPOXY IS NOT CURING

 

Mixing

You can get a well-mixed product with a stick, but a mechanical mixer is easier and more effective.  The key is to get to the areas on the side, bottom and corners of the bucket.  Once mixed, the best way to prevent un-cured patches within the applied product is to pour the mixed product in another empty bucket.  The goal is to get the hardener distributed equally within the resin.  Any resin without the infusion of hardener will remain uncured.

 

Low Temperatures

Dynesic epoxies are formulated for application at temperatures above 40–45ºF.  Temperatures below 40ºF will stop the rate of the chemical reaction between the epoxy and the hardener. Once the temperature rises above 40-45º, the product will continue to cure, however the cure time is slower in cold temperatures.

 

Be aware that surface temperatures may be much lower than the air temperature.  Epoxy coating jobs should wait for recommended temperature ranges, and not be applied when temperatures are expected to fall below the minimum recommended temperature during the first 72 hours of cure.

 

High Humidity, Moisture Condensation, Stagnant Air

High humidity will also slow cure times, but will otherwise not affect the performance of Dynesic products. 

 

Remaining Oils, Greases or Chemicals on the Surface

The surface must be free of oils, greases or chemicals for the product to perform.  These areas can be cleaned with trichloroethylene, or any optimum degreasing agent then washed thoroughly.

 

Remaining Acids on the Surface

The surface must be free acids for the product to perform.  These areas can be neutralized with baking soda.
