Clariant Hostavin® 3212 LIQ is a high-efficiency synergistic liquid light stabilizer, blending oxalanilide-based UV absorber and low-molecular-weight HALS at 2:1 ratio. It features low in-can color, good stability to metal ions, and excellent QUV test performance.
Adopts synergistic formula of UV absorber and HALS, with significantly higher light stabilization efficiency than single components.
Low in-can color, no additional off-color introduced when mixed with coating systems, ensuring appearance quality.
Good tolerance to metal ions, no discoloration risk when contacting metal substrates.
Excellent miscibility with common organic solvents like n-butanol and xylene, compatible with various coating systems.
Active content is about 86%, high effective component ratio reduces addition amount and usage cost.
Suitable for automotive exterior coatings, providing long-term weather resistance and UV protection for vehicle bodies.
Applicable to industrial equipment coatings, enhancing anti-aging and color retention of mechanical surface coatings.
Compatible with solvent-based architectural coatings, improving durability of exterior wall and outdoor component coatings.
Used in metal substrate-specific coatings, solving the discoloration problem of coatings on metal surfaces.
Applicable to plastic substrate coatings, strengthening light stability of polyolefin and other plastic surfaces.
