Technical Data Sheet LOCTITE(R) 3106TM April-2007 LOCTITE(R) 3106TM is primarily designed for bonding rigid or flexible PVC to polycarbonate where large gap filling capabilities and flexible joints are desired. The product has shown excellent adhesion to a wide variety of substrates including glass, many plastics and most metals. The thixotropic nature of LOCTITE(R) 3106TM reduces the migration of liquid product after application to the substrate. TYPICAL PROPERTIES OF UNCURED MATERIAL Specific Gravity @ 25 C Refractive Index Flash Point - See MSDS Viscosity, Brookfield - RVT, 25 C, mPa*s (cP): Spindle 4, speed 20 rpm 1.08 1.48 3,500 to 7,500LMS TYPICAL CURING PERFORMANCE LOCTITE(R) 3106TM can be cured by exposure to UV and/or visible light of sufficient intensity. To obtain full cure on surfaces exposed to air, radiation @ 220 to 260 nm is also required. The speed of cure will depend upon the UV intensity and spectral distribution of the light source, the exposure time and the light transmittance of the substrates. Stress Cracking Liquid adhesive is applied to a polycarbonate bar 6.4 cm by 13 mm by 3 mm which is then flexed to induce a known stress level. Stress Cracking, ASTM D 3929, minutes: 7 N/mm stress on bar 12 N/mm stress on bar >15 13 to 14 Fixture Time Fixture time is defined as the time to develop a shear strength of 0.1 N/mm.

Note: When exposed to a V Bulb at irradiances of 50 and 100 mW/cm for 30 seconds, a depth of cure greater than 13 mm was achieved.

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 1. This product is light sensitive; exposure to daylight, UV light and artificial lighting should be kept to a minimum during storage and handling. 2. The product should be dispensed from applicators with black feedlines. 3. For best performance bond surfaces should be clean and free from grease. 4. 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. 5. Recommended intensity for cure in bondline situation is 5 mW/cm minimum (measured at the bondline) with an exposure time of 4-5 times the fixture time at the same intensity.

For dry curing of exposed surfaces, higher intensity UV is required (100 mW/cm). 7. Cooling should be provided for temperature sensitive substrates such as thermoplastics. 8. Crystalline and semi-crystalline thermoplastics should be checked for risk of stress cracking when exposed to liquid adhesive. 9. Excess adhesive can be wiped away with organic solvent. 10. Bonds should be allowed to cool before subjecting to any service loads. Loctite Material SpecificationLMS LMS dated April-22, 2002.
