Typical usage ratio

• 0.3–1.0% by weight of total coating solids, selected based on targeted UV spectrum coverage and compatibility with other stabilizers

Downstream process integration

• Additive introduced during high-energy premix for basecoat and clearcoat formulation
• Dispersed using sand mill or high-shear rotor-stator systems for optimal distribution
• Post-application thermal curing process does not degrade the additive

Final product types

• Automotive OEM finish basecoats
• Clearcoats for passenger and commercial vehicles
• Protective coatings for exterior automotive plastic components

3. UV-Resistant Adhesives and Sealants for Construction

In the construction industry, sealant and adhesive manufacturers rely on this UV absorber to prevent yellowing and loss of adhesion in joints exposed to direct sunlight. Application typically occurs in silicone, polyurethane, or MS-polymer formulations, which serve critical roles in curtain walls, structural glazing, and exterior sealant systems where longevity and visual stability are mandatory.

Industry compliance standards

• EN 15651 (Sealants for non-structural use in joints in buildings)
• ASTM C920 (Standard Specification for Elastomeric Joint Sealants)
• ISO 11600 (Building construction — Sealants — Classification and requirements)

Typical usage ratio

• 0.2–0.6% of total formulation weight, subject to color requirements and weather-resistance class

Downstream process integration

• Added during compounding after pre-polymer mixing
• Dispersed prior to final packaging and cartridge filling
• Stable under shearing and curing conditions of typical sealant production lines

Final product types

• Structural glazing silicones
• PU construction adhesives
• Facade and expansion joint sealants

4. Sunlight-Stable Packaging for Personal Care Products

Packaging converters in the personal care sector use this additive to improve the UV stability of PET and PE bottles, jars, and containers. Its early intervention during polymer melt processing ensures that lotions, shampoos, and sunscreen formulations remain unaffected by UV-related packaging degradation and preservative loss, supporting shelf-stability and product safety for global brands.

Industry compliance standards

• EU Framework Regulation (EC) No 1935/2004 for food contact materials (analogous use for cosmetic packaging)
• FDA 21 CFR 177.1630 (Polyethylene phthalate polymers for food contact)
• ISO 9001:2015 (QMS for plastic packaging manufacturing)

Typical usage ratio

• 0.1–0.3% per total polymer mass, adjusted for wall thickness and transparency requirements

Downstream process integration

• Metered addition at hopper during extrusion blow molding or injection molding
• Integrated directly into PET or PE pellet blending prior to bottle forming
• Maintains UV protection after sterilization or surface treatment

Final product types

• PET/PE bottles for shampoo, conditioner, and sunscreen
• Cream and lotion jars
• Cosmetic tubes and dispensers

5. UV Shielding for Synthetic Leather and Upholstery Coatings

Producers of synthetic leather and PVC-based upholstery coatings apply this UV absorber to extend the product lifetime of seating and interior components used in automotive, aviation, and commercial furniture sectors. The additive is blended during the plastisol formulation or topcoat lacquering stage, providing lasting color retention and resistance against UV-driven plasticizer loss and embrittlement.

Industry compliance standards

• ISO 105-B02 (Color fastness to artificial light, Xenon arc fading lamp)
• REACH Annex XVII (Restrictions on certain dangerous substances in PVC)
• EN 71-3 (Migration of certain elements, relevant for furniture in sensitive environments)

Typical usage ratio

• 0.25–0.7% per formulation weight, higher for light-colored or outdoor-grade products

Downstream process integration

• Introduced during plastisol blending for wet PVC systems
• Mixed with topcoat or lacquering dispersions for final surface application
• Thermal cure and embossing steps retain additive efficiency
