Technical Data Sheet Cure Time Cure Time TYPICAL PROPERTIES OF CURED MATERIAL % of Full Strength on Steel Cure Speed vs. Substrate The rate of cure will depend on the substrate used. The graph below shows the breakaway strength developed with time on M10 steel nuts and bolts compared to different materials and tested according to ISO 10964. % of Full Strength on Steel TYPICAL CURING PERFORMANCE Cure Speed vs. Activator Where cure speed is unacceptably long, or large gaps are present, applying activator to the surface will improve cure speed. The graph below shows the breakaway strength developed with time on M10 zinc dichromate steel nuts and bolts using Activator SF 7471™ or SF 7649™ and tested according to ISO 10964. TYPICAL PROPERTIES OF UNCURED MATERIAL Specific Gravity @ 25 °C 1.11 Flash Point - See SDS Viscosity, Brookfield - RVT, 25 °C, mPa·s (cP): Spindle 4, speed 20 rpm 4,000 to 15,000 LOCTITE® 272™ is designed for the permanent locking and sealing of threaded fasteners. The product cures when confined in the absence of air between close fitting metal surfaces and prevents loosening and leakage from shock and vibration. Typical applications include the locking and sealing of large bolts and studs (M25 and larger). PRODUCT DESCRIPTION LOCTITE® 272™ provides the following characteristics: Technology Acrylic Chemical Type Dimethacrylate ester Appearance (uncured) Red-orange liquid Components One component requires no mixing Viscosity Medium Cure Anaerobic Secondary Cure Activator Application Threadlocking Strength High % of Full Strength on Steel Cure Time Physical Properties: Coefficient of Thermal Expansion, ISO 11359-2, K-1 Coefficient of Thermal Conductivity, ISO 8302, W/(m·K) Specific Heat, kJ/(kg·K) TYPICAL PERFORMANCE OF CURED MATERIAL Adhesive Properties Cure Speed vs. Temperature The rate of cure will depend on the temperature.
