Description |
Tiangang® HS-112 is a highly effective radical scavenger belonging to the Hindered Amine Light Stabilizers (HALS) family of stabilizers based on an aminoether functionality, also called NOR HALS. It is a liquid HALS with low basicity, and outstanding light stabilities in applications, like coatings, printing ink, and polyurethane lacquer. It prevents the surface from blowing-out, peeling-off, or chalking for pigmented paint, and is particularly suitable for high solid, acid catalyzed automotive and industrial coatings with high efficiency. Though not soluble in water, its liquid form also allows easy emulsification in water. It also has strong synergistic effect when used with a UV Absorber. |
