Permabond

LH197 Flexible Gasketmaker, Green

In Stock

Permabond® LH197 is an anaerobic material that makes 'formed in situ' gaskets between metal surfaces. It is highly flexible, making it ideal for dissimilar surfaces where differential thermal expansion and contraction could be an issue. Due to its flexibility, it is easy to remove and suitable for gasketing applications where routine disassembly is required or on soft metal surfaces such as certain aluminum alloys which damage easily.

Flexible
Replaces all sizes of formed gaskets
Ideal for bonding dissimilar metals
Suitable for use with non-ferrous metals
Can be dismantled with normal tools

Physical Properties of Uncured Adhesive

Chemical composition: Acrylic
Appearance: Green
Viscosity @ 25°C:
- 2rpm: 50,000 mPa.s (cP)
- 20rpm: 20,500 mPa.s (cP)
Specific Gravity: 1.1
UV fluorescence: Yes

Typical Curing Properties

Maximum gap fill: 0.3mm (0.012")
Time taken to reach handling strength (M10 steel) @23°C: 20 minutes*
Time taken to reach working strength (M10 steel) @23°C: 3-6 hours
Full strength (M10 steel) @23°C: 24 hours

*Handling time at 23°C / 73°F. Copper and its alloys will make the adhesive cure more quickly, while oxidized or passivated surfaces (like stainless steel) will reduce cure speed. To reduce curing time, use Permabond activator A905 or ASC10 alternatively, increasing the curing temperature will reduce curing time.
