UV-1577 Hydroxyphenyl-Triazine UV Absorber

UV-1577 (CAS 147315-50-2, formula C27H27N3O2) is a hydroxyphenyl-triazine (HPT) UV absorber for polycarbonate, PET, and high-heat engineering plastics. The triazine chromophore absorbs ultraviolet light strongly and withstands high processing temperatures, so it protects clarity and color where older absorbers would break down. RawSource supplies UV-1577 in bulk against your grade and volume.

RawSource supplies UV-1577 as a technical hydroxyphenyl-triazine UV absorber comparable to Tinuvin 1577 (BASF). RawSource is an independent distributor and is not affiliated with, endorsed by, or sponsored by the brand owners; the brand names are used only to identify the comparable commercial grade.

Hydroxyphenyl-triazine absorbers such as UV-1577 give higher ultraviolet absorption and better thermal stability than benzophenone and first-generation benzotriazole grades, which is why they are used in demanding engineering plastics and high-solids coatings. UV-1577 is a solid grade suited to polycarbonate and polyester at high melt temperature.

Applications

Polycarbonate and engineering plastics

In polycarbonate and other high-heat engineering resins, UV-1577 provides strong ultraviolet protection with the thermal stability the melt demands, holding clarity and color in glazing, sheet, and molded parts.

PET and polyester

In PET and polyester, UV-1577 screens ultraviolet light through hot processing without breaking down, protecting film and molded parts that see the sun.

High-solids and durable coatings

In high-solids and high-durability coatings, the triazine chromophore delivers strong, long-lasting ultraviolet absorption in the film.

Host polymers and typical use

UV-1577 is dispersed into the polymer or coating during compounding or formulation, where it absorbs ultraviolet light before it can break polymer chains, fade pigments, or dull the surface. The systems below are where UV-1577 is most often specified.

Typical use levels for polymer UV absorbers fall in the 0.1 to 1.0 percent range, set by part thickness, expected outdoor exposure, and the co-stabilizer package (commonly a hindered-amine light stabilizer). Confirm loading on the bench and the exact specification on the Certificate of Analysis for each lot.

Handling and regulatory status

UV-1577 is an industrial UV absorber for engineering plastics and coatings. It is a hydroxyphenyl-triazine with low aquatic toxicity and is not on the EU REACH Candidate List; follow the Safety Data Sheet for the exact classification and handling.

Bulk UV-1577 Supply from RawSource

RawSource supplies UV-1577 hydroxyphenyl-triazine UV absorber in bulk to coatings, plastics, and polymer compounding buyers and their purchasing teams. We source to your target grade, purity, and physical form across domestic and import channels, so we match specification, lead time, and landed cost to your program. Multiple qualified producers make UV-1577 to a common identity, which keeps supply competitive and available on demand.

Every lot ships with a Certificate of Analysis (CoA) and the current Safety Data Sheet (SDS). We source to order rather than carry fixed stock, so pricing and availability are confirmed by quote. Send your grade, annual volume, and any specification limits for a current bulk price.
