Permabond® MH196 is an anaerobic material designed for making “formed in situ” gaskets between metal surfaces. It is capable of replacing a wide range of conventional gaskets, thereby offering potential for reduced stock holdings. By allowing surface to surface contact, load transmission can be improved. As the product does not shrink, creep or relax after curing, no bolt re-tightening is required. It has excellent chemical and high temperature resistance or up to 200°C.
FEATURES AND BENEFITS
- Instant low pressure seal
- Replaces all sizes of formed gaskets
- Good high pressure resistance
- High temperature resistance
- Does not creep or shrink
