Product Description
Vulkem 346 Top Coat is applied after the Vulkem 350NF base coat and 346 intermediate coat have fully cured. It is designed for strong interlaminary adhesion to the Vulkem 346 intermediate coat; confirm adhesion requirements and recoat windows against the current TDS. The aliphatic polyurethane chemistry is formulated for UV stability compared to aromatic alternatives; confirm UV performance against the TDS. The system is designed to protect concrete from water damage, freeze/thaw cycling, de-icing salts, chemicals, and fuel exposure; confirm chemical compatibility against the TDS and project specification.
System Overview — Vulkem 350NF/346/346
Vulkem 346 Top Coat is the final layer in the Vulkem 350NF/346/346 cold-applied traffic deck coating system:
- Base Coat: Vulkem 350NF — single-component urethane waterproofing membrane
- Intermediate Coat: Vulkem 346 — aliphatic polyurethane build coat
- Top Coat: Vulkem 346 — UV-stable aliphatic polyurethane wear surface
Key Characteristics
- UV-stable, aliphatic formula — formulated to resist yellowing and degradation under UV exposure; confirm UV performance against the TDS.
- Abrasion resistance properties — formulated as a durable wear surface for vehicular and pedestrian traffic; confirm load ratings against the TDS.
- Chemical resistance properties — formulated with resistance to fuels, oils, de-icing salts, and chemicals; confirm chemical compatibility against the TDS and project specification.
- Waterproofing system role — designed to protect concrete and occupied areas below from water damage as part of the complete system; confirm system design against the current Tremco specification.
- Interlaminary adhesion — designed for adhesion to the Vulkem 346 intermediate coat; confirm application window and surface condition requirements against the TDS.
- Cold-applied — no heat required; applied at ambient temperatures within the temperature range specified in the TDS.
Typical Applications
- Parking garages and parkade decks
- Pedestrian walkways and plaza decks
- Concrete slabs over occupied areas
- Traffic deck systems exposed to de-icing salts and chemicals
