Drometrizole Chemical Properties,Uses,Production

Characterization

Drometrizole is an ultraviolet light absorber (UVA) of the hydroxyphenyl benzotriazole class, imparting good light stability to a wide variety of polymers.

Applications

Drometrizole provides ultraviolet protection in a wide variety of polymers including styrene homoand copolymers, engineering plastics such as polyesters and acrylic resins, polyvinyl chloride, and other halogen containing polymers and copolymers (e.g. vinylidenes), acetals and cellulose esters. Elastomers, adhesives, polycarbonate blends, polyurethanes, and some cellulose esters and epoxy materials also benefit from the use of Drometrizole.

Features/benefits

Drometrizole features a strong absorption of ultraviolet radiation in the 300-400 nm region. It also has a high degree of photostability over long periods of light exposure. The high absorbance combined with photostability and the ability to release absorbed energy in non sensitizing ways make Drometrizole an effective stabilizer against the effects of ultraviolet light.

Guidelines for use

The use levels of Drometrizole range between 0.10% and 0.50%, depending on substrate and performance requirements of the final application. Drometrizole can be used alone or in a variety of blends and combinations with Ciba IRGAFOS®, Ciba IRGANOX® and Ciba CHIMASSORB® stabilizers where often a synergistic performance is observed. Drometrizole may react with various heavy metal ions to form salts or complexes. For example, if Drometrizole comes into contact with iron or cobalt ions, colored complexes are formed. Reducing and oxidizing agents used in polymerization and curing processes have no effect on the stability of Drometrizole.

Physical Properties

Safety

In accordance with good industrial practice, handle with care and avoid unnecessary personal contact. Protect skin. Prevent contamination of the environment. Avoid dust formation and ignition sources.

Chemical Properties

Light yellow powder

Uses

Drometrizole is an intermediate reactant in the synthesis of UV light absorbers for polyester fibers.

Uses

An ultraviolet light absorber for stabilizing plastics and other organic materials against discoloration and deterioration.

Uses

2(2-Hydroxy-5-methylphenyl)benzotriazol is an UV adsorber for use in plastics, cosmetics, dental materials, acrylic materials, dyes, etc.

Definition

Drometrizole is a member of triazoles.

Application

Intermediate reactant in the synthesis of UV light absorbers for polyester fibers
Reactant for synthesis of:
Benzotriazole UV absorbers with a blocked hydroxy group for us in UV curable paint
Maleimide-bound benzotriazole monomer to use for emulsion polymerization
Used in:
