PRODUCT INTRODUCTION
Our Light Stabilizer is a high-performance UV protection additive designed to protect polymers, coatings, paints, plastics and textile materials from sunlight, UV radiation and photo-oxidation. By absorbing harmful UV light and quenching free radicals, the Light Stabilizer prevents yellowing, chalking, cracking, gloss loss and mechanical degradation of finished products exposed to outdoor environments.
There are two main types of Light Stabilizer: UV absorbers, which absorb harmful ultraviolet rays before they damage the material, and hindered amine light stabilizers (HALS), which scavenge free radicals and interrupt the photo-oxidation chain reaction. Depending on the substrate and end-use, we supply powder, granular or liquid Light Stabilizer grades to meet different processing and formulation requirements.
The Light Stabilizer shows excellent compatibility with most polymer systems, coating resins, pigments and other additives. Within the recommended dosage, it maintains color stability, transparency and mechanical properties without causing bloom, haze or interference with processing. It is widely used in automotive parts, outdoor furniture, building materials, coil coatings, wood coatings, plastic films, fibers and agricultural films.
Every Light Stabilizer batch is tested for UV absorption efficiency, solubility, melting point, color, dispersion and thermal stability before delivery. COA, TDS and MSDS are provided for quality traceability and export compliance. Our technical team can recommend the most suitable Light Stabilizer grade and dosage according to your substrate, exposure condition and performance target.
POINTS FOR ATTENTION
ORDER INSTRUCTIONS
1. Confirm Application and Performance Target
Please tell us your substrate type, exposure condition, UV protection requirement, color target and any regulatory preference. We will recommend the most suitable Light Stabilizer grade.
2. Trial Sample and Testing
We can provide trial samples of the Light Stabilizer for lab evaluation. Customers are welcome to test UV stability, color change, gloss retention and long-term aging performance.
3. Confirm Packaging and Quantity
The Light Stabilizer is available in powder (25 kg bags / cartons) or liquid (25 kg / 200 L drums, IBC tanks). Custom labels and shipping marks are available for export orders.
4. Delivery and After-sales Support
Each batch of Light Stabilizer is supplied with COA, TDS and MSDS. Our technical team provides after-sales support for dosage adjustment, compatibility testing and formula optimization.
Trial Order Tip:
For new customers, we recommend a small trial batch first to verify the Light Stabilizer performance in your actual production process before bulk ordering.

USAGE NOTES
Dosage Control:
The recommended dosage of the Light Stabilizer is 0.1–2.0%, depending on substrate and exposure condition. Start from the lower limit and increase gradually after performance testing.

Adding Method:
Add the Light Stabilizer during the early compounding or dispersion stage to ensure uniform distribution. Liquid grades can be pre-blended with the carrier resin or solvent.

Compatibility Check:
Before mass production, test the Light Stabilizer with other additives such as antioxidants, pigments, fillers and processing aids. Observe color, transparency and dispersion changes.

Exposure Condition Consideration:
Select the Light Stabilizer grade according to the outdoor exposure intensity, film thickness and required service life. High-intensity UV areas may require higher dosage or HALS combination.

COMMON PROBLEMS IN DOWNSTREAM PRODUCTION
Yellowing or Discoloration After Sun Exposure
UV radiation degrades the polymer surface, causing yellowing, chalking and dull appearance.
Solution: Increase the Light Stabilizer dosage or use a UV absorber + HALS combination for stronger protection.
Gloss Loss and Chalking on Coating Film
Outdoor coatings lose gloss and develop chalky surface due to photo-oxidation of the resin.
Solution: Use a more effective Light Stabilizer grade and verify gloss retention through accelerated weathering tests.
Cracking and Brittleness in Plastic Parts
Long-term UV exposure causes surface cracking, brittleness and reduced mechanical strength.
Solution: Add a higher dosage of HALS-type Light Stabilizer and combine with antioxidant for synergistic protection.
Poor Compatibility with Pigments
The Light Stabilizer may interact with some pigments, causing color shift, haze or bloom.
Solution: Run a compatibility test before production and select a Light Stabilizer grade compatible with your pigment system.
Bloom or Surface Migration on Film
Excess Light Stabilizer may migrate to the surface, causing a whitish bloom or haze.
Solution: Reduce the Light Stabilizer dosage or switch to a grade with lower migration tendency.
Reduced Transparency in Clear Products
Incorrect Light Stabilizer grade or dosage may affect clarity of transparent films and parts.
Solution: Select a high-transparency Light Stabilizer grade and keep dosage within the recommended range.
Insufficient UV Protection in Thin Films
Thin films may not absorb enough UV if the Light Stabilizer dosage is too low or grade is unsuitable.
Solution: Increase dosage proportionally with film thickness reduction and consider a higher-efficiency grade.
Batch-to-Batch Performance Variation
Changes in resin quality, processing temperature or additive ratio may cause inconsistent UV protection.
Solution: Standardize the Light Stabilizer grade and dosage, keep process parameters stable, and perform incoming batch testing.
