Vulkem® 350NF/950NF/951NF modified polyurethane traffic deck coating system composed of a base coat (350NF)

Vulkem® 350NF/950NF/951NF is a modified polyurethane traffic deck coating system composed of a base coat (350NF), heavy duty intermediate coat (950NF) and a top coat (951NF).

This unique waterproofing system is designed to have tenacious adhesion, extreme impact and abrasion resistance along with remarkable chemical stability. The elastomeric properties of the system’s components enable the complete assembly to give and work with the concrete slab, bridging the shrinkage cracks.

Vulkem 350NF Base Coat is a single-component, low odor, low VOC, urethane membrane that bonds firmly to clean, dry concrete and metal. It retains its integrity even if substrate movement causes hair-line cracks of up to 1/16" (1.5 mm). If cut or damaged, Vulkem 350NF will prevent water migration between itself and the substrate.

Vulkem 350NF is available in roller (R) and in self-leveling (SL) grade for vertical and horizontal application. Vulkem 950NF Intermediate Coat is a low VOC, two-component urethane that is applied after the Vulkem 350NF Base Coat has cured. The intermediate coat is loaded with aggregate to give the system excellent impact, abrasion and chemical resistance.

Vulkem 951NF Top Coat is an aliphatic, low VOC, two-component polyurethane that is applied after the Vulkem 950NF intermediate coat has cured.

Interlaminary adhesion to Vulkem 950NF is exceedingly strong. The top coat affords excellent abrasion resistance, UV stability and chemical resistance to complete this Vulkem Traffic Deck Coating System.
