(4) the dosage of curing agent and accelerator should be adjusted according to the need (such as product performance, operating temperature and the length of service life, etc.).Accelerants may not be added to the hot - curing formulation.Curing at room temperature can be adjusted according to the gel time, can be determined in the case of curing agent dosage, change the amount of accelerator to adjust, usually, curing agent dosage of resin weight of 2-4%, promoter dosage of 1-2%.
