Cure Properties
Condensation Cure Grades
Condensation cure grades cure with exposure to atmospheric moisture. The cure process begins from the outer surface and proceeds inward.
Therefore, deep section curing (in excess of 6mm) is not recommended. Typically, tack-free is achieved in 5-60 minutes at 25
depending on the grade.
Cure Time Test Method: Liquid silicone inserted in a 10mm diameter glass tube, and measurements of the cure length taken at specific intervals.
Heat Cure Grades
Heat cure grades consist of either 1 part or 2 part grades, and are characterized by a cure mechanism this is triggered by exposure to heat.
Cure performance is affected by temperature and time, resulting in a variety of cure profiles based upon the combination of these variables. The
following examples demonstrate the effect of temperature and time in hardness change and manifestation of adhesive strength.
