열경화형 실리콘은 백금 촉매의 활동을 방해하는 물질과 접촉하여 경화 불량이 발생하는
현상을 말한다. 이러한 경화 저해 물질로는 아민류, 유황화합물, 유기주석 화합물 등이
있으며 이를 함유한 물질 즉 축합형 실리콘, 유기고무, PVC 등과 접촉하면 경화가 되지
않으므로 주의하여 적용해야 한다.


* 유기금속염 - 연질PVC, 축합형 실리콘 고무
* 질소화합물 - 아민경화형 에폭시 수지, 땜납플럭스
* 유황화합물 - 천연고무, 합성고무
* 유기과산화물 - 불포화 폴리에스테르 수지, 합성고무
* 인화합물 - 가역제
* 기타 - 플라스틱 도료, 고무 등의 경화제, 노화방지제, 산화방지제 등
