Loctite 270 Adhesive Threadlocker Green 50ml

  • Strength : High
  • Key Substrates : Metal: Brass, Metal: Steel, Metal: Steel - Stainless Steel
  • Color : Green
  • Curing Type : Anaerobic
  • Application : Threadlocking
LOCTITE® 270 is a high-strength threadlocker for maximum efficacy in the securing and sealing of bolts, nuts and studs to prevent loosening due to vibration. The product serves to permanently lock assemblies which must not come loose. It works on all metals, including passive substrates such as stainless steel, aluminum and plated surfaces. It is proven to be tolerant of minor contamination due to industrial oils, e.g. motor oils, corrosion prevention oils and cutting fluids. Can be disassembled by heating to 300°C.
  • High-strength general threadlocker for maximum efficacy
  • Prevents loosening on vibrating assemblies, e.g. pumps, gear boxes or presses
  • Works on all metals, including passive substrates (e.g. stainless steel, aluminum, plated surfaces)
  • Proven to be tolerant of minor contamination due to industrial oils, e.g. motor oils, corrosion prevention oils and cutting fluids
  • Permits disassembly with hand tools
  • Can be disassembled by heating to 300°C
  • P1 NSF Reg. No.: 123006
LOCTITE®
270™ is designed for the permanent locking and
sealing of threaded fasteners. The product cures when
confined in the absence of air between close fitting metal
surfaces and prevents loosening and leakage from shock and
vibration. LOCTITE®
270™ is particularly suited for heavy duty
applications such as studs into motor housings, nuts onto studs
in pump housings and other fasteners where high strength is
required. LOCTITE®
270™ provides robust curing
performance. It not only works on active metals (e.g. brass,
copper) but also on passive substrates such as stainless steel
and plated surfaces. The product offers high temperature
performance and oil tolerance. It tolerates minor surface
contaminations from various oils, such as cutting, lubrication,
anti-corrosion and protection fluids.
NSF International

Registered to NSF Category P1 for use as a sealant where
there is no possibility 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 breakaway strength developed with time on
M10 steel nuts and bolts compared to different materials 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 depends on thread type, quality and size.
The following graph shows 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 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 steel nuts and
bolts using Activator 7471™, 7649™, 7088™ and 7091™ and
tested according to ISO 10964.
GENERAL INFORMATION

This product is not recommended for use in pure oxygen
and/or oxygen rich systems and should not be selected as
a sealant for chlorine or other strong oxidizing materials
For safe handling information on this product, consult the
Material Safety Data Sheet (MSDS).
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.
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. If the cure speed is too slow, use appropriate activator.
    Please see the Cure Speed vs. Activator graph for
    reference. Allow the activator to dry when needed.
  3. To prevent the product from clogging in the nozzle, do not
    allow the tip to touch metal surfaces during application.
  4. For Thru Holes, apply several drops of the product onto
    the bolt at the nut engagement area.
  5. For Blind Holes, apply several drops of the product to the
    lower third of the internal threads in the blind hole, or the
    bottom of the blind hole.
  6. For Sealing Applications, apply a 360° bead of product
    to the leading threads of the male fitting, leaving the first
    thread free. For bigger threads and voids, adjust product
    amount accordingly and apply a 360° bead of product on
    the female threads also.
  7. Assemble and tighten as required.

For Disassembly


  1. Remove with standard hand tools.
  2. In rare instances where hand tools do not work because
    of excessive engagement length, apply localized heat to
    nut or bolt to approximately 250 °C. Disassemble while
    hot.
  3. Apply localized heat to the assembly to approximately
    250 °C. Disassemble while hot.

For Cleanup


  1. Cured product can be removed with a combination of
    soaking in a Loctite solvent and mechanical abrasion
    such as a wire brush.
