ENDRUST® UB302B is a heavy-duty, bituminous rustproofing sealant for motor vehicles, designed to meet AS2662 standards. Ideal for undercarriage protection (floor pans, firewalls, chassis, wheel arches), this black, waterproof compound prevents rust, suppresses noise, and resists stone chips. It forms a durable, flexible coating that shields 4WDs from sand, mud, and debris while reducing road noise. Easy to apply with minimal sag, it provides long-lasting protection for your vehicle.

Q: Why should I choose a bituminous-based rustproofing product like Endrust over rubberized coatings?
A: Bituminous-based rustproofing products, such as Endrust, are less likely to trap moisture compared to rubberized coatings. Moisture entrapment can promote corrosion over time, making bituminous-based coatings a preferable choice for effective rust protection.

Q: What is the advantage of using a thixotropic rustproofing product?
A: Thixotropic rustproofing products, like Endrust, offer multiple advantages. They provide enhanced protection against chipping and abrasion, thanks to their ability to absorb and dissipate energy upon impact or friction. Thixotropic coatings also accommodate the flexing of the substrate, ensuring that the protective layer remains intact even under dynamic conditions.

Q: How does bituminous-based rustproofing prevent moisture entrapment?
A: Bituminous-based rustproofing, such as Endrust, minimizes moisture entrapment due to its thixotropic properties. The coating remains in a higher viscosity state when at rest, reducing the risk of moisture becoming trapped between the coating and the metal surface. This characteristic helps prevent the accumulation of moisture, which can lead to corrosion.

Q: Will a thixotropic rustproofing product like Endrust protect against chipping and abrasion?
A: Yes, thixotropic rustproofing products excel in providing superior protection against chipping and abrasion. The reversible viscosity change in thixotropic coatings, such as Endrust, allows them to absorb and dissipate energy during impacts or friction, minimizing the risk of coating damage and preserving the integrity of the protective layer.

Q: Is a thixotropic rustproofing product suitable for vehicles with substrate flexing?
A: Absolutely. Thixotropic rustproofing products, like Endrust, offer flexibility to accommodate substrate movement, including vibrations, expansions, and contractions. This flexibility ensures that the protective layer remains intact, preventing the formation of cracks or gaps that could expose the substrate to corrosion-causing elements.

Remember to consult with professionals or experts in rustproofing to understand specific application guidelines and the best solution for your vehicle’s needs.
