Description
xOverview
5121 Alphathane is a high-strength, self-leveling sealant designed for flat RV surfaces such as roofs. It tends to flow and settle evenly, creating a smooth bead that reduces the need for heavy tooling and helps a clean finish across repaired seams.
Designed to work with wood, metal, glass and most common RV roof materials, this sealant aims to deliver reliable adhesion on horizontal decks, roof panels, and edge joints. Its formulation is crafted to tolerate the vibrations and shocks that come with travel and road conditions, while resisting outdoor exposure.
What makes it stand out
When fully cured, the product does not shrink, which helps maintain a consistent seal along long roof seams. The color options include beige, gray, almond and white, making it easier to match the look of different RV exteriors.
Alpha Systems offers a holistic lineup of tapes, sealants, adhesives and cleaners that are formulated to work together as a complete repair system. All Alpha products are manufactured in the USA and backed by Lippert Components, a name trusted by RV manufacturers, dealerships and service technicians.
