Urethane Activator Med 3:1 70-80 Degrees F

The Urethane Activator Med 3:1 70-80 Degrees F by EASTWOOD is a single-stage ceramic urethane paint activator formulated for professional automotive refinishing and restoration work. This activator is essential for anyone mixing custom urethane base coat or clear coat systems, providing the chemical catalyst needed to initiate the cross-linking polymerization process that hardens and protects your paint job. Designed for use in moderate temperature environments, this activator ensures optimal cure times and paint adhesion when applied within its specified temperature range.

The 3:1 mixing ratio indicates that three parts urethane paint should be combined with one part activator by volume, creating a chemically balanced mixture that cures uniformly and develops full hardness and gloss characteristics. The medium activator formulation is engineered specifically for 70–80 degrees Fahrenheit ambient temperatures, allowing painters to achieve ideal pot life and flash-off timing without accelerated curing that could cause runs or imperfect leveling. This 1-quart can delivers sufficient activator to mix with three quarts of base coat or clear coat, making it practical for both single-panel touch-ups and full vehicle applications in standard shop conditions.

Professional automotive painters, collision repair technicians, and custom vehicle restoration specialists benefit most from this ceramic urethane activator when working on multi-layer paint systems that demand durable, high-gloss finishes resistant to UV fade and chemical exposure. The activator is compatible with EASTWOOD urethane paint systems and most ceramic-enhanced urethane coatings designed for automotive use; always verify brand compatibility before mixing. Proper ventilation and spray equipment calibration are essential when using any urethane activator, and strict adherence to the 3:1 ratio ensures correct cure speed and final paint performance across temperature-controlled shop environments.
