Bonding Learder special hardener for automotive paint, as a drying aid, is widely used in the process of preparing automotive paint. BD hardener, the main ingredient is Aliphatic isocyanate. The use of aliphatic polyisocyanates enables paint coatings to have the following advantages: gloss retention, non-yellowing, chemical resistance, aesthetics, abrasion resistance, durability, and impact resistance. Our hardener is generally used together with 2K paint and 2K primer. When mixing, we need to pay attention to stir the hardener and 2K paint evenly, and use it up within 1 hour, otherwise the prepared paint will harden .
