Tetrosyl Exh001 Red Hardener For Resin Body Fillers - 40gm x2

The red hardener paste acts as an activator for Tetrosyl Polyester fillers. It initiates a chemical reaction that causes the filler to cure and harden, making it ready for sanding and finishing.

The exact ratio depends on the specific Tetrosyl Polyester filler being used. Always refer to the instructions on the filler's packaging for the recommended amount of hardener. Typically, it's a very small proportion relative to the filler volume.

No, this Tetrosyl Exh001 Red Hardener is specifically formulated for use with all Tetrosyl Polyester fillers only. Using it with other brands or types of fillers may result in improper curing, poor adhesion, or failure of the repair.

The curing time (or 'pot life' and 'set time') varies depending on the specific filler, the amount of hardener used, and ambient temperature. Generally, the filler becomes workable for a short period (e.g., 5-10 minutes) and then hardens enough to be sanded within 20-30 minutes.

If insufficient hardener is used, the filler will not cure properly. It may remain soft, gummy, or weak, making it impossible to sand or paint, and the repair will likely fail over time.

Using too much hardener can cause the filler to cure too rapidly, reducing your working time significantly and potentially leading to excessive heat generation during curing. It can also make the cured filler brittle.

Store the hardener tubes in a cool, dry place, ensuring the caps are tightly sealed after each use to prevent the paste from drying out or degrading.

This usually indicates insufficient hardener was mixed in. Ensure the correct ratio is used according to the filler's instructions and that the hardener is thoroughly mixed. Check that the hardener has not expired or dried out.

Too much hardener was used, or the ambient temperature is very high. Carefully measure the hardener and filler. Work in a cooler environment if possible. Use the mixed filler immediately.

The hardener was not mixed thoroughly into the filler. Ensure the red color is completely uniform throughout the mixture before application.

The nozzle may be partially blocked by dried paste. Carefully clear any obstruction with a pin or small tool. Ensure the cap is sealed tightly when not in use.
