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 or 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 extended “open time” which allows up to 5 minutes in the mixing container at 70º F and up to one hour working time on the surface being coated.   EX-74 is waterproof, heat & alcohol resistant.
