Technical Data Sheet

LOCTITE

511™

September-2005

PRODUCT DESCRIPTION

LOCTITE

511™ provides the following product

characteristics:

Technology Acrylic

Chemical Type Dimethacrylate ester

Appearance (uncured) White to off-white paste

LMS

Components One component - requires no mixing

Viscosity Medium, thixotropic

Cure Anaerobic

Application Sealing

Strength Low

LOCTITE

511™ is designed for the locking and sealing of

metal threaded pipes and fittings. The product cures rapidly

when confined in the absence of air between close fitting metal

surfaces.

TYPICAL CURING PERFORMANCE

Cure Speed vs. Substrate

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

below shows the breakaway strength developed with time on

M10 steel nuts and bolts compared to different materials and

tested according to ISO 10964.

Zinc dichromate

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.

The following graph shows the shear strength developed with

time on steel pins and collars at different controlled gaps and

tested according to ISO 10123.

Cure Speed vs. Temperature

The rate of cure will depend on the ambient temperature. The

graph below shows the breakaway strength developed with

time at different temperatures on M10 steel nuts and bolts and

tested according to ISO 10964.

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 graph below shows the breakaway strength

developed with time on M10 zinc dichromate plated steel nuts

and bolts using Activator 7649™ and tested according to ISO

10964. The use of Activator 7471™ is not recommended with

this product.

TDS LOCTITE® 511™, September-2005 7. For Sealing Applications, apply a 360° bead of product to the leading threads of the male fitting, leaving the first thread free. Force the material into the threads to thouroughly fill the voids. For bigger threads and voids, adjust product amount accordingly and apply a 360° bead of product on the female threads also. 8. Assemble and tighten as required. For Disassembly 1. Remove with standard hand tools. 2.
