1.Weighing: mix A & B components separately, weigh A & B components as per weight ratio 1:1 exactly.
2.Mixing: put B component to A component, mix evenly, it can be finished by hand or equipment.
3.Defoaming: defoamed in the vacuum condition.
4.Potting: clean the surface that needed to be coated, put the rubber into the mould.
5.Curing: curing at room temperature or by heating. In room temperature, the viscosity of rubber will increased along with time extension, it would double with 40-60 minutes.

A & B Components separately.
