The Cure for Cold Resin

Most people are unaware of the drastic difference in performance and/or the physical state of epoxy resin caused by exposure to freezing temperatures.

Epoxy resin is sensitive to temperature and it's curing process can be compromised in low temperatures. 

The Symptoms:

• higher viscosity

• crystallized or solidified resin 

• white, cloudy color

• waxy consistency

• slower reactivity

• longer cure times

• lower cured performance

Freezing causes the resin to crystallize or develop seed crystals and makes the resin much thicker than it's normal viscosity, reduce the polymer’s reaction rate, extend its cure time, and ultimately affect it's polymerization. 

EcoPoxy is manufactured in Canada where temperatures  drop to -30°F and stay below 0°F for more than half of the year. In these conditions, product stored in a climate controlled environment will freeze in the short time it takes to load a transport truck, during transport or waiting for clearance at the border.

When it does freeze, it usually thaws before it's unloaded in the US, leaving no indication. So, despite all efforts, EcoPoxy epoxy resin kits can freeze, at some point in time, before reaching their final destination, the consumer.

 This can be reversed by warming Part A Resin before using in a hot water bath and then store in a temperature-controlled environment no cooler than 70°F.

 During the colder months, Part A & B should be warmed to 75°F to 80°F (21°C to 27°C) prior to use to lower its viscosity, This also reduces air bubble entrapment, maintains its working time and will insure proper cure.
