METALGRADE HI-TEMP

When used on heavy sections and where build-up will exceed 9 mm (3/8") use the following technique: Fill section up to 9 mm (3/8") in one step. Let the product fully cure (16–24 hours) before adding another 9 mm (3/8") in a second step. Let the product cure again. Continue this procedure until the groove is filled. The reason for 9 mm (3/8") maximum thickness per layer for the Hi-Temp product is that it is a single component system in an aqueous solution. The water must have the possibility to dry out. The water in sections above 9 mm (3/8") would not dry out, and upon exposure to high temperatures would effervesce and bubble. It is also recommended that the paste be heat cured at 90 °C (200 °F) between applications.

For repairing holes, repairs should be made using a metal screen. First apply Hi-Temp, then form and place the screen inside the hole and then apply second coating of Hi-Temp to cover the screen.

When the material is fully cured for a minimun of 24 hours at 20 °C (68 °F), sanding, grinding and machining etc. can be carried out using standard engineering practices. Hi-Temp exhibit high thermal conductivity as well as excellent resistance to abrasives, fuels, oils and solvents.

5. Cleaning

In uncured state Hi-Temp is cleaned up with soap and water.
