product deion
loctite® product 4206 is a single component, fast fixturing,
clear, thermal resistant, low viscosity cyanoacrylate instant
adhesive. it is formulated with elastomers for flexibility and
improved resistance to heat, humidity or damp environments.
product 4206 has excellent hot strength and heat aging
capabilities at temperatures up to 121°c for periods in excess of
2,000 hours.
typical applications
bonding of a wide range of metal, plastic or elastomeric
materials. loctite 4206 has usp class vi certification and is
suitable for use in assembly of disposable medical devices.

typical curing performance
under normal conditions, the surface moisture initiates the
hardening process. although functional strength is developed in
a relatively short time, curing continues for at least 3 days
before full chemical/solvent resistance is developed.
cure speed vs substrate
the rate of cure will depend on substrate used. the table
below shows the fixture time achieved on different materials at
22°c , 50% relative humidity. this is defined as the time to
develop a shear strength of 0.1 n/mm2 (14.5 psi) tested
according to astm 1002.
substrate fixture time, seconds
steel (degreased) 10 to 20
aluminum 5 to 10
abs 5 to 10
sbr (smooth) 45 to 60
nbr 10 to 20
epdm 45 to 60
phenolic 10 to 20
cure speed vs bond gap
the rate of cure will depend on the bondline gap. high cure
speed is favored by thin bond lines. increasing the bond gap
will slow down the rate of cure.
cure speed vs activator
where cure speed is unacceptably long due to large gaps or low
relative humidity, applying activator to the surface will improve
cure speed. however, this can reduce the ultimate strength of
the bond, therefore testing is recommended to confirm effect.
approvals
product 4206 has been granted usp class vi certification
which makes it particularly suited for use in disposable medical
device assemblies. product 4206 has also passed hemolysis
and cytotoxicity testing.
directions for use
for best performance surfaces should be clean and free of
grease. this product performs best when gaps are less than
0.25mm. excess adhesive can be dissolved with loctite clean
up solvents, nitromethane or acetone.
storage
product shall be ideally stored in a cool, dry location in
unopened containers at a temperature between 8°c to 21°c
(46°f to 70°f) unless otherwise labeled. optimal storage
conditions for unopened containers of cyanoacrylate products
are achieved with refrigeration: 2°c to 8°c (36°f to 46°f).
refrigerated packages shall be allowed to return to room
temperature prior to opening and use.
