The Relationship Between Air, Metal And Anaerobic Adhesive

Anaerobic adhesives remain liquid until isolated from oxygen in the presence of metal ions, such as iron or copper.   These adhesives are used in a variety of applications including threadlocking, retaining, pipe sealing, and gasketing and are often referred to as sealants instead of adhesives.

The relationship between the amount of air, metal and adhesive/sealant is significant in the manufacturing, packaging and use of these products.   Manufacturing Air is introduced in manufacturing to ensure stability.  Packaging Products are packaged in containers that permit sufficient air permeation.   Use During use, the type of metal and the gap and between the two surfaces are the main contributors to speed of cure. Metal ions on the surface of the substrate are generally sufficient.  In the event no metal is present or a less reactive metal is used.  Surface conditioners may be used.

For the majority of applications, the balance of air, metal and adhesive happens with no extraordinary attention.  For example, when an anaerobic adhesive is sealed between a nut and a bolt on a threaded assembly, it rapidly cures or hardens to form a tough cross-linked plastic that will bond quite well to many metals.

The significance of this balance is more pronounced when pushing the technology to hone in on the best possible use parameters.  Such as the ideal surface finish to obtain the fastest cure rate.

Surface finish affects the quantity of air, adhesive and metal ions present.   If the surface finish is too small, the air in the adhesive does not have a suitable pathway to escape to permit cure.  If the surface finish is too large, excess air and adhesive is present (relative to the amount of metal) to permit cure through the gap.

To determine the ideal micro finish for a low viscosity wicking grade threadlocker, the % cure after 45 minutes was determined on various surface finishes.

More of a pool tip than a ??

Talk bout handy 1/2 hr ago a freind of mine at the bar asked me to shape a tip on his new stick . a Wally special but i was looking Around for some sandpaper and another guy said he had some so he went out and got it it had an adhesive backing on it so i start sanding the same guy asked how do you know its right i told bout a nickel dome thing he said be right back .He brought in a peice of 3/4 in pvc pipe he had split in half long ways stuck the paper inside and made the best tip shaper i have ever used and quick
I even touched up the fishing pole with it great idea you might wanna try it im looking at all my sticks but prob not some have never been chalked
Just passin it on Later Johnny
OK Im busted its a old pre dot Mucci the best shaft ever made a red or black dot does not compare to it Thanks Kid--I think

Your so-called "fishing pole"...Just what kind of shaft do you have on that?

Thanks for the tip
