All properties are printed at 20°C. The catalogue gives LM-11D a +100°C upper limit; the manufacturer's earlier product page states +120°C.

Reference values from the Chaoyang Guangda LM catalogue — typical figures rather than guaranteed limits. Confirm the exact model and concentration on the current model TDS before specifying.

Before you specify

Combustible. The catalogue identifies LM-11, LM-11A and LM-11F as hazardous chemicals. Obtain the current SDS for the exact model.

FROM FORMULATION TO APPLICATION

For water-sensitive process systems.

The LM-11C, LM-11D and LM-11E product references describe anhydrous, water-insoluble fluids for industrial indirect cooling and model-dependent heating duties.

01 / APPLICATION NOTE

Clean, dry, then fill

System preparation should address residual moisture and previous fluid. The original references call for cleaning and drying before filling, followed by measures to prevent moisture ingress.

02 / APPLICATION NOTE

Discuss system closure

Volatility and moisture sensitivity make system closure important. The LM-11E reference also discusses nitrogen sealing; obtain a model-specific engineering and safety review.
