Description

Vulkem® 351NF is a low-VOC, two-component, aliphatic polyurethane top coat designed for use over Vulkem 350NF in pedestrian waterproofing systems. When combined with the recommended aggregate, it creates a durable, UV-resistant, and skid-resistant surface ideal for foot traffic and exposed environments. It forms a strong interlaminate bond with Vulkem 350NF to complete a seamless, elastomeric waterproofing system.
