What is cure time, tack time, and tool time?
Tool Time Tool time is the amount of time you have to work with an adhesive or sealant once it has been applied to a surface. When it begins to cure or “skin over,” you can no longer work the sealant into position. Tack Time Tack is the property of being sticky or adhesive. So “tack-free” is the time it takes for a bead of product to cure to a point in which it can be touched without sticking to it. It does not necessarily mean the sealant is cured throughout. Open Time The time from when the material is applied to a surface to the time it has reached a hardened state. Cure Time Cure time is the point at which the sealant has reached its full properties. The precise cure time depends on the size of the bead and environmental conditions such as humidity and temperature.
