Bis(1,2,2,6,6-pentamethylpiperidin-4-yl) decanedioate (cas: 41556-26-7) belongs to piperidine derivatives. Piperidine is a saturated organic heteromonocyclic parent, an azacycloalkane, a secondary amine and a member of piperidines. Fluorinated piperidines are also the subject of continued interest in medicinal chemistry, for example in the synthesis of selective dipeptidyl peptidase II (DPP II) inhibitors. Piperidine derivatives are also used in solid-phase peptide synthesis (SPPS) and many degradation reactions.Recommanded Product: 41556-26-7

Weathering resistance of waterbased UV-cured polyurethane-acrylate coatings was written by Decker, C.;Masson, F.;Schwalm, R.. And the article was included in Polymer Degradation and Stability in 2004.Recommanded Product: 41556-26-7 This article mentions the following:

The light stability of water-based UV-cured polyurethane-acrylate (PUA) coatings has been tested in an accelerated QUV-A weatherometer. IR spectroscopy was used to monitor both the ultrafast polymerization of the acrylate double bond upon intense illumination, and the chem. changes occurring upon photoageing of 30 渭m thick clearcoats. The UV-curing reaction was hardly affected by the addition of the HALS radical scavengers and UV absorbers needed to improve the light stability of waterbased UV-cured PUA coatings. The 伪-hydroxyphenyl ketone used as photoinitiator was shown to disappear rapidly upon UV-curing and early QUV exposure, thus having no detrimental effect on the weathering resistance. The urethane linkage (C-NH) is the most sensitive to photodegradation Such waterbased PUA coatings were found to be as resistant to weathering as typical UV-cured PUA coatings. In the presence of light stabilizers, they undergo only minor chem. changes after as much as 4800 h QUV-A ageing, the surface erosion being restricted to a few micron thick layer. The observed permanency of the UV-absorber after such heavy exposure ensures a longlasting UV-screen effect of the protective coating. Water-based UV-cured PUA coatings proved to be more resistant to hydrolysis than melamine-acrylate thermosets. In the experiment, the researchers used many compounds, for example, Bis(1,2,2,6,6-pentamethylpiperidin-4-yl) decanedioate (cas: 41556-26-7Recommanded Product: 41556-26-7).
