Freezing is a hot tip for releasing rusted bolts
There's hardly anything worse for an engineer than a rusted nut, bolt or stud. Trying to free it can hold up a job, cause frustration and cost money. Now there's a new - and highly effective way of releasing those stubborn components, and it will stop engineers getting hot under the collar. It's called Loctite Freeze and Release, and that's exactly what it does.
Once the corroded parts have been cleaned of loose dirt and rust, the spray is applied directly from the can. An application of between five and ten seconds is enough to instantly chill seized and rusted parts down to '43'C. The exceptional shock-freeze effect produces a differential thermal contraction that creates microscopic cracks in the layer of rust. This, in turn, allows the lubricant ingredient of the spray to wick directly into the rust by means of capillary action. The assembly can then be easily dismantled.
