PERMABOND® HM161 Anaerobic Retaining Compound

Permabond® HM161 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 the mated parts. Thus it prevents their movement relative to each other, eliminating wear, erosion and pitting. HM161 cures to a tough cross-linked plastic that will prevent the corrosion of mated parts and provides excellent environmental and temperature resistance
