Drying time at 60°C
Clear coat is ready to polish after baking for about 30 minutes and cooling down (about 4 hours).
Temperatures below 20°C significantly increases the drying time.
IR drying
15÷20 minutes under short wave depending on the total thickness and type of radiator.
Do not exceed maximum temperature of 60°C.
Use according to the recommendations of the equipment manufacturer.
Wait about 10 minutes before starting IR drying.
Performance
1 liter of the mixture is enough to paint 6÷7 m2 of surface with a layer thickness of 50 μm.
Shading
Make sure you have covered all the surface with the clear coat. You should only shade the surface that has been covered and treated. Use InterTroton FADE OUT THINNER to clean any dust or dirt from the surface and to level out the optical gloss differences between the older and new applied coating.
Polishing and eliminating defects
Usually polishing is unnecessary, as the CT 538 2:1 gives the surface a perfect finish immediately after application. However, if some dirt inclusions appear, we recommend removing them and then polishing the surface with an abrasive compound.
Caution: Do not polish matt coatings!
General notes
- Do not exceed recommended doses of the hardener!
- The best repair results can be achieved by painting at room temperature. The temperature in the body shop and the temperature of the product should be similar. When working with 2K products, it is recommended to use personal protection equipment. Protect the eyes and airways.
- The rooms should be well ventilated.
- Clean the guns and equipment immediately after use.
Caution: To maintain safety, always follow the instructions given in the MSDS for the products.
