PRODUCT DESCRIPTION
\nLOCTITE\u00ae 3108\u2122 provides the following product characteristics:
\nTechnology Acrylic
\nChemical Type Acrylated urethane
\nAppearance (uncured) Translucent colorless liquidLMS
\nComponents One component – requires no mixing
\nViscosity Medium
\nCure Ultraviolet (UV) light
\nCure Benefit Production – high speed curing
\nApplication Bonding
\nFlexibility Enhances load bearing & shock absorbing characteristics of the bond area.<\/p>\n

LOCTITE\u00ae 3108\u2122 is designed primarly for potting and sealing glass to metal joints that must withstand thermal cycling and environmental exposure. The product has shown excellent capabilities in bonding dissimilar rigid substrates.<\/p>\n

TYPICAL PROPERTIES OF UNCURED MATERIAL

\nFlash Point – See MSDS
\nViscosity, Brookfield – RVT, 25 \u00b0C, mPa\u00b7s (cP):
\nSpindle 4, speed 20 rpm 3,600 to 6,600LMS<\/p>\n

TYPICAL CURING PERFORMANCE
\nLOCTITE\u00ae 3108\u2122 can be cured by exposure to UV light at 365nm. Surface cure is enhanced by exposure to UV light in the 220 to 260 nm range. Cure rate and ultimate depth of cure depend on light intensity, spectral distribution of the light source, exposure time and light transmittance of the substrate through which the light must pass.<\/p>\n

Fixture Time
\nFixture time is defined as the time to develop a shear strength of 0.1 N\/mm\u00b2.
\nUV Fixture Time, Glass, seconds:

GENERAL INFORMATION<\/strong><\/p>\n

This product is not recommended for use in pure oxygen<\/strong><\/p>\n

and\/or oxygen rich systems and should not be selected as<\/strong><\/p>\n

a sealant for chlorine or other strong oxidizing materials<\/strong><\/p>\n

For safe handling information on this product, consult the<\/strong><\/p>\n

Material Safety Data Sheet (MSDS).<\/strong><\/p>\n

Directions for use:<\/strong><\/p>\n

1. This product is light sensitive; exposure to daylight, UV<\/p>\n

light and artificial lighting should be kept to a minimum<\/p>\n

during storage and handling.<\/p>\n

2. The product should be dispensed from applicators with<\/p>\n

black feedlines.<\/p>\n

3. For best performance bond surfaces should be clean and<\/p>\n

free from grease.<\/p>\n

4. Cure rate is dependent on lamp intensity, distance from<\/p>\n

light source, depth of cure needed or bondline gap and<\/p>\n

light transmittance of the substrate through which the<\/p>\n

radiation must pass.<\/p>\n

5. Cooling should be provided for temperature sensitive<\/p>\n

substrates such as thermoplastics.<\/p>\n

6. Plastic grades should be checked for risk of stress<\/p>\n

cracking when exposed to liquid adhesive.<\/p>\n

7. Excess uncured adhesive can be wiped away with organic<\/p>\n

solvent (e.g. Acetone).<\/p>\n

8. Bonds should be allowed to cool before subjecting to any<\/p>\n

service loads.<\/p>\n
