PRODUCT DEscriptION
LOCTITE® Product 3301 is a one component, low viscosity
adhesive which cures rapidly to form flexible, transparent
bonds when exposed to ultraviolet radiation and/or visible light
of sufficient intensity.
TYPICAL APPLICATIONS
Loctite Product 3301 is primarily designed for bonding rigid or
flexible PVC to polycarbonate. These characteristics enable
easy assembly of components with close fitting tolerances (i.e.
joining polycarbonate to flexible PVC tubing). Its flexibility
enhances the load bearing and shock absorbing
characteristics of the bond area. It has also shown excellent
adhesion to a wide variety of substrates including glass, many
plastics and most metals. Loctite 3301 has USP Class VI
Certification. Suitable for use in assembly of disposable
medical devices.

Liquid adhesive was applied to a medical grade polycarbonate
bar 6.4cm by 13mm by 3mm which had been flexed to induce
different stress levels. The time it took for signs of crazing or
stress cracking to appear was recorded.

TYPICAL CURING PERFORMANCE
This product can be cured by irradiation with ultraviolet and/or
visible light of sufficient intensity. To obtain full cure on
surfaces exposed to air, the intensity of UV radiation at 220 to
260 nm will accelerate the tack free cure of surface. The cure
rate and ultimate depth of cure will depend on light intensity,
the spectral distribution of the light source, the exposure time
and the light transmittance of the substrates.
NOTE: UV intensities where quoted are measured at
365nm using an OAI 306 UV Powermeter

Effects of Sterilisation
Products similar in composition to Loctite 3301 subjected to
standard sterilisation by E.T.O. or Gamma Radiation (2.5 and
5.0 Megarads) show excellent bond strength retention. Loctite
3301 has shown excellent bond strength retention following
exposure to 121 - 127°C steam for 30 minutes, 1 cycle.
Repeated autoclaving is not recommended with these
adhesives. It is recommended that customers test specific
parts after subjecting them to preferred sterilisation method.
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 oxidising materials.

Approvals
Product 3301 has been granted USP Class VI certification
which makes it particularly suited for use in disposable
medical device assemblies.
Directions for use
This product is UV sensitive. Exposure to daylight, UV light
and artificial lighting should be kept to a minimum during
storage and handling. Product should be dispensed from
applicators with black feed lines. For best performance bond
surfaces should be clean and free from grease. UV cure rate
is dependent on lamp intensity, distance from light source,
depth of cure needed or bondline gap and light transmittance
of the substrate through which the radiation must pass.
Recommended intensity for cure in bondline situation is 5
mW/cm2 minimum (measured at the bondline) with an
exposure time of 4-5 times the fixture time at this same
intensity. For dry curing of exposed surfaces higher intensity
UV is required (100 mW/cm2 minimum). Cooling should be
provided for temperature sensitive substrates such as
thermoplastics. Crystalline and semi-crystalline
thermoplastics should be checked for risk of stress cracking
when exposed to liquid adhesive. Excess adhesive can be
wiped away with organic solvent. Bonds should be allowed to
cool before subjecting to any service loads.

Storage
Product shall be ideally stored in a cool, dry location in
unopened containers at a temperature between 8°C to 28°C
(46°F to 82°F) unless otherwise labelled. Optimal storage is
at the lower half of this temperature range. To prevent
contamination of unused product, do not return any material to
its original container.
