The exact opposite will occur as temperatures increase above 77 o F. Applications which are allowed to cool below the freezing point must be warmed to achieve a full through Cure. In the case of freezing the solid or film must be checked for hardness to insure full, strength has been achieved. This test is also very helpful when determining if a piece is ready for sanding or machining. The time it takes for an epoxy mixture to change from liquid to solid is the Cure time. Initial cure or gel - 3.
Final cure is when the epoxy is now solid.
Cure times can be sped tip or slowed depending on your need and application by the combining of the different speed hardeners. This happens because the Slow generally has a peak exotherm temperature and the Slow hardener molecules are bulkier, which slows down the chemical reaction between the resin and hardener. The cure times are not directly proportional to the amount of hardener used to customize the blend. For large fillets Medium hardener is recommended. Rub mix into clean surface with scotch brite pad.
