摘要： The present disclosure provides a formula of a remover reagent for a cured silicone sealant and a method using the same. The remover reagent is prepared from an acid catalyst and a solvent each having a high boiling point and a high flash point. The acid catalyst is benzenesulfonic acid or alkylbenzenesulfonic acid. The solvent is mineral oil and/or silicone oil. The cured silicone sealant is first soaked with the remover reagent for 30 to 120 min, and then baked at a high temperature of 80 to 120° C. for 10 min or above into debris or powder, whereby the cured silicone sealant with a thickness of 10 mm or above can be removed. Moreover, the remover reagent has the advantages of readily available raw materials, high safety, environmentally friendliness, convenient preparation and good sealant removal effect, and thus, has good application prospects.
