HH190 Flange Sealant Gasketmaker, Purple
Permabond® HH190 Gasketmaker is an anaerobic curing flange sealant that can replace, or be used as a dressing for, conventional pre-cut gaskets. Since HH190 is a flowable paste, it conforms to the shape of the flange. The consistency allows metal-to-metal contact of the flanges while filling the areas where no contact exists because of irregularities. HH190 results in uniform stress distribution and eliminates the need for re-torquing because of the stress relaxation of the flange bolts. It provides instant seals depending on the gap and flange width and ultimately seals up to 5000psi. It has excellent shock and vibration resistance and can be conveniently dismantled if necessary.
- Eliminates pre-cut gaskets from flange assemblies
- Instant pressure seal
- Forms a tough, durable seal able to withstand
- high pressure
- No need to re-tighten flange bolts
- Non-flammable
- No shimming effects - better load transmission

Physical Properties of Uncured Adhesive
- Chemical composition: Acrylic
- Appearance: Purple
- Viscosity @ 25°C: 300,000 mPa.s (cP) Flowable Paste
- Specific Gravity: 1.1
- UV fluorescence: No
Typical Curing Properties
- Maximum gap fill: 0.3mm (0.012")
- Time taken to reach handling strength (M10 steel) @23°C: 15 minutes*
- 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.
Typical Performance of Cured Adhesive
