PRODUCT DESCRIPTION LOCTITE® 128068™ provides the following product characteristics: Technology Acrylic Chemical Type Methacrylate ester Appearance (uncured) Purple pasteLMS Fluorescence Positive under UV lightLMS Components One component - requires no mixing Viscosity High Cure Anaerobic Application Sealing LOCTITE® 128068™ is a ready-to-use, one component, gel-like anaerobic flange sealant that cures at room temperature when it is isolated from air contact. However, it is designed to cure slowly to avoid shimming between flanges. LOCTITE® 128068™ seals close fitting joints between rigid metal faces and flanges and will flex with minor flange movements. Provides resistance to low pressures immediately after assembly of flanges. Typically used as a form-in-place gasket for transmission housings and axle covers. TYPICAL PROPERTIES OF UNCURED MATERIAL Specific Gravity @ 25 °C 1.1 Flash Point - See SDS Viscosity, Brookfield - HBT, 25 °C, mPa·s (cP): Spindle TB, speed 0.5 rpm, Helipath 300,000 to 1,000,000LMS TYPICAL CURING PERFORMANCE Cure Speed vs. Substrate The rate of cure will depend on the substrate used. An ambient temperature product should not begin to cure for at least 30 minutes on steel. Cure Speed vs. Bond Gap The rate of cure will depend on the bondline gap. This product is not designed to be used on flanges with gaps in excess of 0.1 mm. % of Full Strength on Steel Cure Time, hours 100 75 50 25 0 1min 5min10min 30min 1h 3h 6h 24h 72h No gap TYPICAL PROPERTIES OF CURED MATERIAL Physical Properties: Coefficient of Thermal Expansion, ISO 11359-2, K -1 80×10-6 Coefficient of Thermal Conductivity, ISO 8302, W/(m·K) 0.1 Specific Heat, kJ/(kg·K) 0.3 TYPICAL PERFORMANCE OF CURED MATERIAL Adhesive Properties After 24 hours @ 22 °C Compressive Shear Strength, ISO 10123: Steel pins and collars N/mm2 ≥5.0LMS (psi) (≥725) Lap Shear Strength, ISO 4587: Steel (grit blasted) N/mm2 6 (psi) (870) Tensile Strength, ISO 6922: Steel (grit blasted) N/mm2 14 (psi) (2,030) TYPICAL ENVIRONMENTAL RESISTANCE
