Pre-applied Adhesives - Precote 80

 

Precote is a range of inert, dry to touch and ready to use high performance adhesive products. The thread covered with the adhesive develops its desired locking and sealing properties when compression or shear stress ruptures the micro-capsules after the assembly of the screw. The adhesive is released and within a short time the system hardens. The threads become locked, bonded together and reliably sealed.

Precote 80 pink microencapsulated pre-applied adhesive provides high strength locking and sealing between the male and female thread forms upon assembly. The product is fast curing and provides excellent resistence to vibration even under extreme operating conditions.

Industry Approvals

Our adhesive product is approved to a wide range of industry standards
including:- BS 7795:1995, GM 6175M, Ford WX200 & WX201,
Rover RES.22.FP.01. Plus many other industry approvals.

Product Guide

We currently process a range of Headed Components, Studs, Plugs and similar size parts.
We can apply our coating to ferrous or non-ferrous materials (Steel, Aluminium, Stainless Steel or Brass).
We offer a complete Plate and Patch service.
This is a general guide to the products we currently process. We are able to process other components subject to evaluation.
Re-usability of micro-encapsulated adhesives is not recommended.

 

prelok precote 80

 

prelok adhesive principle

A. The Pre-applied process consists of
applying the micro-encapsulated adhesive onto a defined area of the male thread surface.
B. The adhesive coating is inert, dry to touch, ready to use.
C. Upon assembly into the mating threaded component the micro-capsules
rupture, developing a secure locking of
the 2 components with a high strength
adhesive bond.

Recommendations
 
Hole Preparation
In all cases the female thread of the mating components should have the lead thread de-burred or countersunk to avoid damage to the patch material.
Thread Preparation
To obtain optimum patch performance both male and female threads should be in accordance with class 6g/h (metric) or class 2 a/b (unified).
Finishes
Pre-applied adhesive can be applied to most popular plated finishes, as well as polymer and organic coatings.
Customer free issue components
Parts manufactured from non-ferrous material should be supplied free from any surface contaminants. Variations in material structure can effect heating capability of the part during processing, which may result in torque variation. High installation speeds can create galling of the threads affecting product performance.
Samples
Pre-production samples are evaluated and then processed free of charge.
