Why Choose ZTC959 Ruby Clear Coat?
High Gloss and Film Fullness
For professional refinishing, clearcoat quality is not judged by brightness alone. Film fullness, surface smoothness, reflection clarity, and final appearance also matter.
ZTC959 emphasizes a full, glossy finish for repair projects where the visible surface quality is important. It can be considered for doors, fenders, hoods, quarter panels, and complete vehicle refinishing.
High DOI for a Refined Finish
Distinct image clarity (DOI) describes how clearly objects appear when reflected in a coated surface. It complements gloss as an appearance evaluation factor.
ZTC959 is positioned for workshops seeking both gloss and clear reflection. Actual results depend on surface preparation, spray technique, film build, flash-off, and curing conditions.
Leveling for Consistent Appearance
Orange peel and uneven reflections can be affected by spray-gun setup, viscosity, gun distance, spray speed, thinner selection, temperature, and flash-off time.
Using the recommended ZTC959 mixing system and controlling the application process helps support a smoother, more consistent finish.
Hardener Options for Different Temperatures
ZTC959 uses the ZTH959 hardener series and matching ZK301 thinner series. Select the appropriate combination according to the workshop temperature and product instructions.
-
Below 18°C: ZTH959K fast hardener + ZK301K fast thinner
-
18–30°C: ZTH959B standard hardener + ZK301B standard thinner
-
Above 30°C: ZTH959M slow hardener + ZK301M slow thinner
These are the source-provided temperature guidelines. Follow the current technical instructions for actual workshop conditions.
