Harmonization Code : 38159000 | Unspecified reaction initiators, accelerators, and catalytic preparations
Main features
- 20,000 to 57,000 cP Hardener Viscosity
- 1:1 General-Purpose Volume Mix
- 1- to 2-Hour System Working Time
Product Description
LORD 307-2 is the Part B hardener used with LORD 305-1 resin in a two-component, medium-viscosity epoxy adhesive system. As supplied, the hardener is a clear amber liquid with a typical viscosity of 20,000 to 57,000 cP at 25 deg C and density of 947 to 995 kg/m^3. For general-purpose mixed-stress joints, LORD 305-1/307-2 uses a 1:1 resin-to-hardener volume ratio. A 54 g mixed mass has a typical working time of 1 to 2 hours at 24 deg C, with handling strength in 8 to 16 hours and full strength in 24 to 48 hours at 18 deg C or higher.
Key features
- Hardener Rheology: Typical LORD 307-2 viscosity is 20,000 to 57,000 cP at 25 deg C using Brookfield HBF, spindle 2 at 10 rpm.
- System Mixing: The LORD 305-1/307-2 general-purpose configuration uses a 1:1 resin-to-hardener ratio by volume.
- Mixed-System Work Time: A 54 g LORD 305-1/307-2 mixed mass has a typical working time of 1 to 2 hours at 24 deg C.
Applications
When combined with LORD 305-1, system uses include assembling food-processing machinery such as gaskets, bushings, shock-absorbing devices, and rubber rolls, plus bonding prepared metals and prepared rubber.
