Standard cure butyl rubber vapor barrier coating
ELASTRON 858 is a two component, fire retardant, polymerized butyl rubber coating. It is extremely resistant to the passage of mass water or gas vapor due to its unique, low molecular chemical structure. ELASTRON 858 cures by chemical reaction to form a highly impermeable, elastomeric membrane which also offers excellent chemical resistance. ELASTRON 858 is a pot life system designed for application through standard airless spray equipment or by brush or roller.
ELASTRON 858 was developed primarily for application as a vapor barrier over polyurethane foam, concrete and masonry, wood and metal. The outstanding properties of the coating have created successful applications throughout the world over roofs, in high humidity areas, controlled atmosphere rooms, dry kilns, cold storage areas, over insulated pipelines, and cryogenic storage tanks ?wherever an effective vapor barrier is required. ELASTRON 858 is a U.L. 790 Class "A" classified coating, incorporating non-migrating fire retardants which are dispersed into the raw material complex and are permanently locked into the cured coating. For long term exterior exposure, a number of topcoats may be utilized to provide a barrier to ultraviolet degradation and resistance to all forms of weather. |
