RZ-Ecoseal is a halogen free, waterborne vinyl acetate copolymer dispersion.
A white, elastic mastic which transforms into a hard crust, similar to ceramic, when exposed to high temperatures derived from flames or intensive heat radiation from fire. The insulating capacity of the crust effectively extinguishes the flow of heat to the treated surface. The cured mastic is elastic, weatherproof and resistant to most chemical solutions and is therefore suitable for use in locations with high air humidity and other aggressive environments. RZ-Ecoseal can be repainted with topcoat.
RZ-Ecoseal can be used on surfaces as a delay for heat-transfer and/or condensation. RZ-Ecoseal can also be used for sealing gaps in ductwork to make it water- and airtight. This to prevent oxygen from entering the duct trough leakage openings, in case of fire
