PRODUCT DESCRIPTION
LOCTITE
廬
Product 603 is a single component anaerobic
retaining adhesive for cylindrical joints. The product cures
when confined in the absence of air between close fitting metal
surfaces. This product develops adhesion even on surfaces
lightly contaminated with oil.
TYPICAL APPLICATIONS
Used to bond cylindrical fitting parts, particularly where
consistently clean surfaces cannot be assured. Applications
include retaining roller bearings or oil impregnated bushings
into housings.

Cure speed vs. activator
Where cure speed is unacceptably long, or large gaps are
present, surface activation will improve cure speed. The graph
below shows shear strength developed with time using
ACTIVATOR T and N on zinc dichromated steel pins and
collars and tested according to ISO 10123.
