Permabond AA00040L250B0101

HH040 Gap Fill Anaerobic Retaining Compound, Green, 250ml Bottle

Permabond® HH040 is a single-component liquid that cures only when in contact with metal parts and oxygen is excluded. The liquid adhesive fills the 'air space' between parts and upon cure unitizes and retains male and female parts. Thus, it prevents their relative movement, eliminating wear, erosion, and pitting. HH040 cures to a tough cross-linked plastic that will prevent the corrosion of mated parts and provides excellent environmental and temperature resistance.

Simple one-part system
Shaft-hub assemblies can be made with slip fits
Expensive press fits can be eliminated
High viscosity for maximum gap-filling ability
Excellent shear strength
Superior environmental resistance
Thixotropic viscosity allows easy dispensing

Details

Physical Properties of Uncured Adhesive

Chemical composition: Acrylic
Appearance: Green
Viscosity @ 25°C: 5,000 mPa.s (cP) Thixotropic
Specific Gravity: 1.1
UV fluorescence: Yes

Typical Curing Properties

Maximum gap fill: 0.25mm (0.01")
Maximum thread size: M30 (3/4")
Time taken to reach handling strength (M10 steel) @23°C: 15 minutes*
Time taken to reach working strength (M10 steel) @23°C: 1 hour
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.
