RV Roof Leak Repair & Lap Joint Sealing Engineering
Protect motorhomes, travel trailers, and campervans from vibration-induced water ingress, roof rot, and costly interior delamination with CHEMPU MS-30RV advanced polymer.
Complete RV Roof Overhaul & Resealing
Over time, factory silicone and butyl tapes dry out, crack, and fail under extreme solar UV and chassis twist. CHEMPU MS-30RV forms a permanent rubberized seal.
- Non-cracking elastomeric matrix absorbs severe highway vibration and chassis flex
- Zero solvents or isocyanates: 100% safe for sensitive EPDM and TPO membranes
- Class-leading UV resistance tested for 3,000+ hours accelerated xenon aging
Rooftop Fixtures & Penetration Caulking
Air conditioners, skylights, vent fans, solar brackets, and satellite mounts create over 80 fastener penetrations that require high-build, sag-free perimeter caulking.
- High-build non-sag paste seals vertical flange laps and gaps up to 15 mm
- Instant wet weather resistance: skin forms within 20 minutes even in high humidity
- Compatible with screw heads: completely encapsulates fastener penetrations
Fiberglass, Aluminum & TPO Adhesion
Primerless, ultra-strong adhesion across diverse caravan roof substrates including FRP gelcoat, anodized aluminum, painted sheet metal, ABS plastics, and polyolefin roof membranes.
- Tensile shear strength ≥ 2.2 MPa without toxic primers or etching solvents
- Compatible with thermal expansion differentials between aluminum and fiberglass
- Paintable within 2 hours with automotive acrylics or urethane topcoats
Easy Caulking Gun Application
Standard 300 ml cartridges and 600 ml sausages fit standard manual, pneumatic, and cordless caulking guns. Smooth extrudability down to +5°C without heating pails.
- Clean tooling characteristics with zero messy stringing or sag
- Available in brilliant white, gray, and black to match factory coach finishes
- Private label OEM branding available for caravan manufacturers and aftermarket distributors
