Using it

Mix resin and hardener at 2.5:1 by volume or 6.25:1 by weight. Working life is 30 minutes and gel time is 35 to 40 minutes at 21 °C.

Apply at 15 °C to 30 °C, with the ambient temperature above 15 °C and rising, relative humidity below 85 % and the substrate at least 3 °C above the dew point.

Pre-heating the repair surface until it is warm to the touch speeds cure at low temperatures. Once cured the putty can be machined, drilled, tapped or filed.

Follow it before you apply.

It is typically used in applications with an operating range of -30 °C to 105 °C.

Apply it between 15 °C and 30 °C.
