Available in several packaging options (2.5L, 5L), they are classified according to their drying speed (Hi-Flo for surface applications, standard and medium for thicker layers).
How to Choose Your Sikkens Hardener?
The choice depends on the following elements:
- Depth of the layer to be applied
- Desired drying time
- Type of material to be painted
- Porosity of the substrate
- Nature of the coating to be achieved
The Advantages of Sikkens Hardeners
Composed of reactive agents, Sikkens hardeners form a cross-linked film with high chemical and mechanical resistance. Their main advantages:
- Reduction of drying time
- Easy and uniform application
- Effective waterproofing of the bodywork
- Protection against scratches, dirt, and weather
- Glossy finish and enhanced depth of the clear
How to Properly Use Your Sikkens Hardener?
Follow the proportions indicated on the technical sheet. Use a graduated holder (type Kemtex CUPMIX) to make your mixtures. After homogenization, let it rest for a few minutes before application. The pot life of the mixture is generally 2 hours. After this period, the mixture may become too thick.
For safe use:
- Wear appropriate protective clothing
- Work in a well-ventilated area
- Wash your hands thoroughly after use
