[산업/전자]밀본드 시스템 (TYPE Milbond Adhesive System), MIL-A-48611

 

1. 제품설명

Milbond는 대부분의 유리 대 금속 접착 응용 분야를 위한 엘라스토머-에폭시 접착 시스템입니다.

Milbond 키트에는 0.015"(0.38mm)의 접착 층 두께를 유지하기 위해 군대에서 요청한 적절한 양의 스페이서 재료가 포함되어 있습니다.

Milbond는 군사 사양 MIL-A-48611을 충족합니다.

Milbond는 유리 대 유리, 플라스틱, 금속 대 플라스틱, 금속 대 금속 접착에 사용할 수 있습니다.
