RPS 55 is a one-part, fast-curing polyurethane adhesive sealant for the automotive sector that bonds various materials like metal, painted plastics, and primers. It is easy to apply, can be painted over in 1.5 hours, and cures via reaction with air humidity. The cured sealant provides good resistance to water, humidity, temperature changes, and vibrations.
Key features
- Curing: Cures quickly at ambient temperature by reacting with humidity, making it over-paintable in about 1.5 hours.
- Adhesion: Offers excellent adhesion to a range of automotive substrates, including metal primers, 2k paint coatings, metals, and painted plastics.
- Application: It is easy to apply and smooth, suitable for both sealing and joining.
- Properties: Once cured, it is resistant to water, humidity, temperature fluctuations, and vibrations.
- Uses: Ideal for sealing and bonding in the automotive sector where high mechanical resistance, flexibility, and vibration reduction are required.
Application and cleanup
- Surface preparation: Surfaces must be clean, dry, and free of oil, grease, and rust before application.
- Application temperature: Apply between +5∘Cpositive 5 raised to the composed with power cap C
+5∘𝐶
and
+35∘Cpositive 35 raised to the composed with power cap C+35∘𝐶
, with optimal performance between
+15∘Cpositive 15 raised to the composed with power cap C+15∘𝐶
and
+25∘Cpositive 25 raised to the composed with power cap C+25∘𝐶
.
- Cleanup: Uncured sealant can be cleaned with white spirit or another suitable solvent. Once cured, it must be removed mechanically.
- Over-painting: It is generally over-paintable, but it is advisable to test compatibility first. Be mindful of alcohol or alkyd-resin, which may interfere with the curing process and drying time of the paint.
