You can.

일반적으로 접착제에 가교제를 첨가하면 접착제의 접착력은 증가한다. 그러나 가교제가 일정량 이상 증가하면, 얻어지는 조성물이 오히려 단단하게 굳게 되고 이에 따라 접착제의 접착력은 오히려 감소하게 될 수 있다.In general, adding a crosslinking agent to an adhesive increases the adhesive strength. However, if the cross-linking agent increases beyond a certain amount, the resulting composition becomes rather hard and the adhesive strength of the adhesive may decrease accordingly.
