OEM-Grade Paint Adhesion:
Compatible with most automotive paint systems; can be sanded and painted after skin formation for a perfect finish.
Superior Vibration Resistance:
Absorbs mechanical stress and roadway vibrations without cracking or losing adhesion.
Non-Corrosive Protection:
Safe for use on metals and pre-painted surfaces, protecting against rust and oxidation.
Exceptional Vertical Stability:
Thixotropic non-sag formula allows for easy application on roof gutters and vertical seams.
Movement Accommodation (±20%):
Highly elastic to handle the structural shifts and thermal expansion of vehicle body panels.

Q：What are the advantages of using MS-9815 over traditional PU sealants for body seams?
A：MS-9815 offers superior UV resistance and color stability. Unlike PU sealants, it is isocyanate-free, has a longer shelf life, and provides better long-term resistance to aging and cracking without needing a primer.
Q：Can MS-9815 be integrated into a "wet-on-wet" painting process?
A：Yes. MS-9815 is compatible with most industrial coatings. It can be painted immediately after skin formation (approx. 30 minutes), facilitating faster cycle times in body-in-white or repair operations.
Q：Does this sealant pose a corrosion risk to bare aluminum or galvanized steel?
A：No. MS-9815 uses a neutral-cure silane technology. It is non-corrosive and safe for all metallic substrates, primers, and topcoats commonly used in the automotive industry.
Q：How does the product handle dynamic stress and road vibration?
A：It features a ±20% movement capability and excellent elastomeric recovery. This allows it to absorb the mechanical stresses and vibrations experienced by roof gutters and body panels during vehicle operation.
Q：Is MS-9815 suitable for vertical application without running?
A：Yes, the formula is highly thixotropic (non-sag), allowing for precise application on vertical seams and overhead joints without dripping or losing its profile.
