Clariant Hostavin TB-04 LIQ Light Stabilizer

Clariant Hostavin® TB-04 LIQ is a synergistic blend of triazine UV absorber and non-basic HALS, developed for the long-term stability requirements of high-performance paints and clear coatings. It combines broad-spectrum UV shielding and free radical scavenging capabilities, and exhibits extensive compatibility in both solvent-based and waterborne coating systems.

Features Of Clariant Hostavin TB-04 LIQ Light Stabilizer

  1. The triazine UV absorber can efficiently cover UV-A and UV-B bands, intercept UV-induced coating damage from the source, and provide a wider protection range.

  2. Blended with non-basic HALS, it avoids adverse reactions with acidic components in coating systems, ensuring stronger compatibility. Meanwhile, it can scavenge UV-induced free radicals and block the coating aging chain reaction.

  3. Liquid form allows for accurate metering and uniform dispersion without additional grinding, simplifying the coating production and formulation process and improving production efficiency.

  4. Excellent compatibility with solvent-based/waterborne coating resins and additives, without causing defects such as pinholes, haze or delamination, suitable for multi-formulation systems.

  5. Optimized for clear coatings, it does not affect the light transmittance and gloss of coatings after addition, ensuring the appearance quality and visual effect of high-transparency coatings.

Typical Applications Of Clariant Hostavin TB-04 LIQ Light Stabilizer

  1. Suitable for solvent-based high-performance automotive OEM clear coats, providing long-term UV aging resistance protection for automotive paint and maintaining the mirror gloss and color stability of the paint surface.

  2. Compatible with waterborne architectural exterior wall clear topcoats, balancing environmental protection and weathering performance, and resisting the erosion of sun and rain on wall decorative layers.

  3. Applicable to high-end wood furniture clear coatings, preventing the fading of wood substrates and the yellowing of coatings, and extending the appearance retention period of furniture.

  4. Used in industrial equipment clear protective coatings, such as precision instrument housing coatings, improving the weathering stability of outdoor service equipment.

  5. Suitable for plastic substrate-specific clear coatings, such as ABS and PC electronic and electrical housing coatings, enhancing the synergistic weathering resistance of coatings and substrates.
