H738 HARDENER ULTRA HS NORMAL
BALANCED ISOCYANATE HARDENER FOR HIGH SOLID 2K TOPCOATS AND CLEARCOATS.
KEY FEATURES:
✅ Tailored for UHS and SR Coatings – Specifically engineered to activate HB BODY’s UHS clear coats (e.g., BODY 691 CLEAR UHS SR, C496, or C699), H738 promotes excellent cross-linking, resulting in enhanced film build, long-term gloss retention, and scratch resistance.
✅ Balanced Curing Profile – With a “normal” reactivity rate, this hardener provides the ideal balance between working time and cure speed. It delivers high surface quality without the risks of solvent entrapment, especially in mild temperature environments (64–77°F).
✅ Durability & Clarity – Delivers superior mechanical resistance and a durable finish that protects against chemicals, UV radiation, and environmental factors. Produces a high-gloss, ultra-clear appearance when used with compatible clear coats.
RECOMMENDED USE:
- Compatible with HB BODY HS SR 2K clearcoats and topcoats.
- Ideal for car panels, partial resprays, or full vehicle refinishing.
- Suitable for medium-speed booth cycles.
