LOCTITE

603 is designed for the bonding of cylindrical fitting

parts, particularly where consistently clean surfaces cannot be

assured. The product cures when confined in the absence of

air between close fitting metal surfaces and prevents loosening

and leakage from shock and vibration. Typical applications

include retaining roller bearings or oil impregnated bushings

into housings.

NSF International

Registered to NSF Category P1 for use as a sealant where

there is no possibilty of food contact in and around food

processing areas. Note: This is a regional approval. Please

contact your local Technical Service Center for more

information and clarification.

TYPICAL CURING PERFORMANCE

Cure Speed vs. Substrate

The rate of cure will depend on the substrate used. The graph

below shows the shear strength developed with time on steel

pins and collars compared to different materials and tested

according to ISO 10123.

Cure Speed vs. Bond Gap

The rate of cure will depend on the bondline gap. The following

graph shows shear strength developed with time on steel pins

and collars at different controlled gaps and tested according to

ISO 10123.

TDS LOCTITE® 603, December-2009 performance of the adhesive. 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 Assembly 1. For best results, clean all surfaces (external and internal) with a LOCTITE® cleaning solvent and allow to dry. 2.
