Technical Data
| Product Description | Tiangang® HS-3310 is a synergistic blend of Benzotriazole UV Absorbers, and Hindered Amine Light Stabilizers, HALS to fulfill high cost/performance and durability requirements of both solventborne, and waterborne coatings, and inks. It is highly effective in protecting the substrate against UV induced degradation, such as gloss reduction, cracking, blistering, delamination and color change. Tiangang® HS-3310 is a versatile light stabilizer, and can be used in a variety of solventborne and waterborne industrial and decorative coatings systems. |

| Dosing Level |
Dry Film Thickness (DFT) directly affect the amount of UVA needed. The following amounts are recommended to achieve proper stabilization for given DFT (light stabilizers % are indicated on total formulation): 10-20um, 4.0% - 8.0% 20-40um, 2.0% - 4.0% 40-80um, 1.0% - 2.0% * Exact dosage should be determined in trials covering a concentration range. |

Frequently asked questions
Is HS-3310 for solvent-borne or water-borne systems?
Both. It is a liquid blend that can be added to either; confirm compatibility with the actual resin in a lab trial.
What does a liquid blend buy over powder single components?
Easier addition, accurate metering and no pre-dispersion. In water-borne systems it also avoids the air entrainment and lumping that powders can bring. The trade-off is stricter packaging and storage conditions.
Will it break a water-borne emulsion?
That depends on the surfactant system and pH. Run a lab trial and watch stability over 24–48 hours before settling the addition method (pre-diluted dropwise, or pre-mixed with the binder).
The figures and guidance above follow Tiangang's published technical material and common industry practice. For a specific formulation, refer to the batch COA and the technical agreement between the parties.
