Frequently Asked Questions
What substrates can Sika Primer-207 be used on?
Sika Primer-207 is suitable for float glass, ceramic-coated glass, plastics, pre-coatings, painted surfaces, E-coats, and metals.
How do I apply Sika Primer-207?
Apply a thin, uniform coat using a suitable applicator (e.g., felt applicator or brush) within the recommended temperature range. Refer to the technical data sheet for detailed application instructions.
What is the ideal application temperature for Sika Primer-207?
The ideal application temperature range for Sika Primer-207 is between 15°C and 25°C.
Can Sika Primer-207 be used on plastics prone to stress cracking?
While effective on many plastics, it is highly recommended to perform substrate testing on plastics prone to stress cracking to ensure compatibility and prevent adverse reactions.
How long does the UV fluorescence of Sika Primer-207 last?
The UV fluorescence is designed for in-process control immediately after application to confirm coverage. It aids in verifying the application layer, but the duration of visible fluorescence is not a primary performance metric.
