Why OB1 Is the Best Sealant on the Market

OB1 stands head and shoulders above the competition when it comes to reliability and versatility. This advanced sealant can bond and seal in wet or dry conditions, won’t shrink or crack over time, and is fully paintable.

One Tube Does It All! OB1 replaces mastics, wood glues, PU adhesives, silicone, acrylic, and butyl rubber sealants—making it the ultimate all-in-one solution. Its unique solvent-free hybrid polymer formula allows for a flexible, durable bond that can expand and contract with metal, wood, and all of the above materials without breaking down.

With a OB1 sealant gun, you can bond almost any surface, including:

• Metals

• PVC

• Glass

• Mirrors

• Polystyrene

• Wood

• Underwater applications

Unlike traditional silicone sealants that can crack or fail over time, OB1’s non-shrinking and non-cracking composition ensures a long-lasting seal, even in extreme temperatures ranging from -40°C to +120°C.

Whether you’re installing a mirror, fixing leaking gutters, sealing a bath, or working on a marine project, OB1 provides an exceptional bond that can handle both indoor and outdoor conditions. OB1’s food-safe and zero-VOC formula also makes it a superior, eco-friendly choice for anyone looking for a high-performance sealant that meets diverse needs.
