EX-74 is an extremely clear, tough, high gloss surface coating formulated to produce a deep glass like appearance in a single layer on a sealed surface. Two of more layers are often applied for added depth and protection. EX-74 has been formulated for improved UV resistance to reduce yellowing and surface degradation from UV exposure. EX-74 has an open time of 25 minutes if poured immediately after mixing (70F). Warmer temperature will reduce open time, therefore it is recommended to pour immediately to allow for self-leveling of the epoxy and maximum bubble release. EX-74 is waterproof, heat & alcohol resistant.
