Application instructions for ULTRAMIX HotFix refractory high-temperature adhesive:

1. Before applying the adhesive, remove dirt, deposits, oil, rust, etc. from the surface of the part.

2. Fit the adhesive dispensing nozzle and cut it to the required size, then extrude the adhesive onto the cleaned surface so that it spreads evenly. Then fix the surfaces to be bonded in place.

3. Leave the coated parts exposed to air and allow the adhesive to cure at room temperature for 24–48 hours. If a waterproof layer is required, bake at a temperature above 200 degrees for an additional hour.

Storage:

Store in a cool, dry place; shelf life is 6 months at temperatures below 25 ℃.

Packaging:

300 ml cartridges or as specified by the customer.

Because this product can be used in a wide variety of practical applications, the conditions of a specific application cannot be predicted precisely. Therefore, the suitability of this product for the specific application must be carefully verified before use.
