METALGRADE HI-TEMP

Instructions for use

Before proceeding, please read the following information application carefully to ensure that proper procedures are fully understood. Metal Grade Hi-Temp repair compound is a ceramic and stainlessfilled one-part water based paste. It is formulated using the most advanced inorganic resin technology and is temperature resistant up to 1093 °C (2000 °F). Hi-Temp is used to seal joints, defects, cracks and voids in cast iron, steel and stainless steel. NB. Hi-Temp should not be used on aluminium or aluminium alloys.

1. Surface preparation

Heavy contamination due to oil or grease should be removed using a cleaner. Abrasive blasting is the preferred surface preparation. A) Remove all contamination (oil, grease and dirt) with a cleaner. B) Remove all loose rust and surface coatings.

C) Roughen the surface, preferably with abrasive blasting. Alternatively, a die grinder, needle scalar or angle grinder may be used. If grinding, make sure the surface is roughened, not polished. Where grinding or needle gunning is used, the surface should be cross-scored to improve adhesion. D) To ensure that all contamination is removed, carry out a final degreasing vith a cleaner. Cloths should be frequently changed to avoid spreading of contamination. On deeply pitted surfaces of porous castings, the cleaner should be worked into the surface with a brush and washed off using excess cleaner. If embedded oils are present in porous castings, they should be burned out at high temperature.

E) Parts (for example, threads or bearing surfaces) which must remain in position during application but which should not adhere to Hi-Temp must be coated with a release agent.

2. Mixing

Hi-Temp is a ready to use, single

part paste. Prior to applying the

product, make sure content is mixed thoroughly by stiring. Use a small spatula and apply required amount of product onto a clean working surface.

3. Application

Prepared surfaces should be dry. Use a spatula or putty knife and press the material onto the prepared area, working the material into any cracks and surface defects. Hi-Temp can be used for applications up to 9 mm (3/8") thick. Let the product air dry for five to seven hours at room temperature.
