LOTSORB UV 360 (CAS:103597-45-1)

Characterization

Lotosrb® UV 360 is a very low volatile, dimeric 2-hydroxy benzotriazole UV-absorber used in a variety  of polymers and resin compositions.

Chemical name

2,2’-methylenebis(6-(2H-benzotriazol-2-yl)-4-1,1,3,3-tetramethylbutyl)phenol)

CAS number

103597-45-1

Structure

Molecular weight

659 g/mol

Applications

Lotosrb® UV 360 applications include acrylic resins, polyalkylene terephthalates, polycarbonates, modified polyphenylene ether or sulfide compounds, polyamides, polyacetals, polyolefins, styrenics, elastomers and high performance plastics

Features/benefits

Lotosrb® UV 360 is particularly suitable for processing and aging conditions where high loads, low  volatility and good compatibility are required. The specific objective is to achieve high UV-screen  performance and minimize sublimation through vents as well as prevention of deposits on molds,  chill-rolls or calibrators. It can prevent exudation/crystallization on end-parts during manufacturing  or exposure to high service temperatures. Such requirements are especially critical for complex moldings, fibers, sheets, twin wall sheets, thin  films, adhesive layers and laminated or co-extruded semi-finished parts.

Guidelines for use

Lotosrb® UV 360 (0.2 - 10% by weight) can be readily incorporated in the polymer by using conventional techniques such as powder, solution, or melt blending (e.g. extrusion compounding).

Physical Properties

Absorption Spectrum (10 mg/l, Chloroform

Lotosrb® UV 360 exhibits strong absorbance in the  300-400 nm region and minimal absorbance in  the visible region (> 400 nm) of the spectrum.  The absorption maxima are at 308 nm and 349  nm (e = 31895 l/mol·cm) in chloroform solution
