Lippert Components 5160 Alphathane RV Non-Sag Sealant — White, Vertical-Grade Weather-Resistant Adhesion

When you need a durable seal for window frames, door surrounds, flashing, or other vertical seams on your RV, the Lippert Components Alpha Systems 5160 Alphathane offers a professional-grade option. Designed for dissimilar substrates, it adheres to wood, metal, glass and common construction materials, cures to a resilient finish, and comes in four colors to better blend with your RV’s exterior or interior trims.

How does 5160 Alphathane handle vertical gaps and joints?

The non-sag formulation ensures the sealant stays put on vertical surfaces while it cures, preventing run-off or stringing. It provides a thick, flexible bead that resists shrinkage and maintains contact across irregular joints.

• Non-sag chemistry for vertical application without tooling loss
• Flexible cured bead tolerates movement between dissimilar materials
• High initial tack helps bridge gaps and uneven surfaces

Will this sealant stick to the materials on my RV?

Yes — 5160 Alphathane is formulated for strong adhesion to a range of common RV materials. It bonds well to metals, glass, wood, and many plastics used in recreational vehicles, making it suitable for window and door sealing and for flashing details.

• Trusted adhesion on metal and painted surfaces
• Reliable contact with glass and wood framing
• Works on many construction substrates found in RV assemblies

Is 5160 safe and practical for indoor and outdoor use?

This sealant contains no solvents or isocyanates and is formulated to be odor-free, which makes it comfortable for use inside cabins as well as on exterior surfaces. Once cured, it resists weathering from sun and moisture so it performs well through seasonal exposure.

• Odor-free formula suitable for enclosed spaces
