Cure speed vs. activator
Where cure speed is unacceptably long, or large gaps are
present, applying activator to the surface will improve cure
speed. The following graph shows breakaway strength
developed with time using ACTIVATOR N and T on M10 Zinc
Dichromate steel nuts & bolts and tested according to
ISO 10964.

Cure speed vs. bond gap
The rate of cure will depend on the bondline gap. Gaps in
threaded fasteners depend on thread type, quality and size.

on steel pins and collars at different controlled gaps and tested
according to ISO 10123.

This product is not normally recommended for use on plastics
(particularly thermoplastic materials where stress cracking of
the plastic could result). Users are recommended to confirm
compatibility of the product with such substrates.
Directions for use
For best performance surfaces should be clean and free of
grease. Product should be applied to the bolt in sufficient
quantity to fill all engaged threads. This product performs best
in thin bond gaps, (0.05mm). Very large thread sizes may
create large gaps which will affect cure speed and strength.
This product is designed to give controlled friction,
(torque/tension ratio), during assembly. In critical tightening
applications this ratio should be confirmed.
Storage
Product shall be ideally stored in a cool, dry location in
unopened containers at a temperature between 8°C to 28°C
(46°F to 82°F) unless otherwise labelled. Optimal storage is at
the lower half of this temperature range.
To prevent
contamination of unused product, do not return any material to
its original container. For further specific shelf life information,
contact your local Technical Service Centre.

Where aqueous washing systems are used to clean the
surfaces before bonding, it is important to check for
compatibility of the washing solution with the adhesive. In
some cases these aqueous washes can affect the cure and
performance of the adhesive.
