Dricon® Tempus® fire retardant is a proven successful formulation based on the American Wood Protection Association (AWPA) P50 Standard for Fire Retardants
Dricon® Tempus® fire retardant chemical contains no formaldehyde, halogens, or sulfates
Generates less smoke in the event of a fire
No more corrosive to fasteners and connectors than untreated wood
An important feature of Dricon® Tempus® FRTW is that it responds to exposure to fire. Dricon® chemicals react with combustible gases and tars normally generated by untreated wood and convert them to carbon char and harmless carbon dioxide and water. Wood loses strength in a fire only as its cross section is reduced. The surface char acts to insulate underlying wood and slows the rate at which the cross-sectional area is reduced in size. The carbon dioxide and water vapor dilute the combustible gases to help reduce flame spread.
