Visão geral do produto & principais benefícios
UV-400 is a hydroxyphenyl-triazine (HPT) UV absorber supplied as a liquid for easy incorporation into coatings. HPT absorbers keep their absorption over long exposure, which is why they are used in automotive clear coats and demanding industrial finishes, usually with a HALS.
Bake resistance
Low loss in high-temperature cure.
Liquid format
Easy incorporation into coatings.

Seleção & comparação
Selecting a UV Absorber
| Sua necessidade | O que geralmente funciona |
|---|---|
| Clear or light-colored polyolefin parts and film | Benzophenone (531) or benzotriazole (326) at low loading |
| High processing temperature (computador, BICHO DE ESTIMAÇÃO, PA) | Low-volatility grades: 234, 360 or 1577-type triazines |
| Thin films and fibers | Higher-MW, low-volatility grades so the absorber is not lost in processing |
| Solvent-borne and waterborne coatings | Liquid benzotriazoles (384-2, 1130) or triazine (400), paired with a HALS |
| Outdoor service longer than one season | UV absorber plus a HALS; the absorber filters, the HALS stops radical chains |
| Exports to the EU | Check REACH status first; some benzotriazoles (327, 328) are restricted |
| Replacing an existing grade | Envie seu TDS ou COA atual; we match on chemistry and the parameters you approve |

*Starting points for trials, not fixed recommendations. Loading depends on part thickness, pigment, target service life and the HALS used alongside. UV absorbers and HALS work by different mechanisms and are usually combined.
Embalagem & armazenar
Embalagem
Tipicamente 25 kg pails or 200 tambores de kg; IBC on request. Confirm the pack in the quotation.
Armazenar
Keep containers closed, away from heat and direct sun. Warm gently and mix before use if the liquid has thickened in cold weather. See the SDS.
Tempo de espera & terms
Typically 3–15 business days from order confirmation, depending on quantity. FOB, CIF or DAP to major ports.

Define the exposure
Indoor light behind glass, outdoor temperate climate and desert or tropical exposure need very different packages. Note the target service life and the weathering test you use (xenon or QUV, horas, ΔE or gloss retention).
Match absorber to process and thickness
A UV absorber works by filtering, so it needs enough path length: thick parts need less, thin films and fibers need more and need a low-volatility grade. Check the absorber survives your processing temperature.
Combine with a HALS
For outdoor use the standard approach is UV absorber plus HALS. Send your current package and pigment system and we suggest a starting combination for the trial.
Check regulations before you buy
Some benzotriazoles are restricted in the EU and other markets. Tell us the destination and end use, and we confirm the REACH and food-contact position of the grade before you order.

Triazine or benzotriazole?
Triazines (like 400) are more photostable and resist bake loss, so they suit the most demanding coatings; benzotriazoles such as 384-2 are more economical.
What dosage is typical?
1–3% on binder solids with a HALS.
Is it used in plastics?
It is mainly a coatings product. For plastics, ask about solid triazines or benzotriazoles.
Posso obter uma amostra antes de fazer o pedido?
Sim. Diga-nos o polímero, o teste que você planeja realizar e a quantidade necessária. As amostras são enviadas com um COA para que você possa comparar o lote com o material atual.
E se um COA não corresponder à especificação acordada?
Envie-nos a especificação acordada e o COA mostrando a diferença (parâmetro, unidade e método de teste). Verificamos com o registro do lote de produção antes de você aceitar o material, e substitua ou teste novamente quando o lote estiver fora das especificações.
