(5-Ethyl-1,3-dioxan-5-yl)methyl Acrylate CAS 66492-51-1 CTFA

CN202110498122.8 reports that epoxy resin and linear polyester acrylate are used as the primary resin, and also active monomers and a percentage of polyester are added to get a hybrid UV treatable composition, which is the concept of hybrid network interpenetration innovation, that is, cationic light After the initiator and also complimentary radical photoinitiator are irradiated with light, they will certainly generate strong protonic acid and cost-free radical, and the solid protonic acid will trigger epoxy group breaking-polymerization as well as treating, and the totally free radical will certainly cause double bond splitting and also polymerization curing to form a network interpenetrating framework. Coated externally of iron printing, it has good adhesion, T-bend performance, and additionally has outstanding mechanical residential or commercial properties as well as chemical resistance. Ideally, the weight ratio of epoxy material, polyester acrylate, active monomer, polyester resin, cationic initiator, complimentary radical initiator is 60: (15 ～ 25): (8 ～ 12): 10:3: (0.5 ～ 2). The details method is as complies with:

Add 60g of epoxy resin 3,4-epoxycyclohexylcarboxylate-3,4- epoxycyclohexylmethyl ester (TTA21P, Jiangsu Taitel New Material Modern Technology Co., Ltd.) right into the white corroded steel blending storage tank, at 600rpm After that add 10g of active monomer cyclotrimethylolpropane official acrylate (EM212, Changxing Products Sector Co., Ltd.), 3g of initiator 4-( phenylthio) phenyldiphenylsulfonium hexafluorophosphoric acid under mixing Salt & bis( 4-( diphenylsulfonium) phenyl) sulfide-bishexafluorophosphate, TTA UV-692, Jiangsu Taitel New Product Technology Co., Ltd.), 1.5 g initiator bis( 2, 4,6-trimethylbenzoyl) phenylphosphine oxide (819, Qi Titanium (Shanghai) Chemical Innovation Co., Ltd.), then stirred at 800rpm for 30min; after that added 10g of polyester material (LTH, Evonik Specialized Chemicals (Shanghai)) Co., Ltd.), 20 g of aliphatic polyester acrylate (DR-E524, Eternal Products Sector Co., Ltd.), and then mixed at 1200 rpm for 30 minutes to acquire a UV composition.

The above UV make-up is consistently covered on iron printing with a density of 20 μm, exposed to light source (UV mercury light), light strength (100mW/cm2), as well as irradiation height (150mm) for 20s, and cured to obtain a solvent-free UV printing iron finish.

Checked by traditional approaches, it was not damaged after 1200 frictions, the adhesion was quality 0, as well as the migration quantity was 0.38 μg/ kg. The UV treating make-up revealed by the invention has great attachment, use resistance and also fluidness, as well as the alicyclic epoxy material and also polyester acrylate as the major resin endow the UV healing composition with much better mechanical residential or commercial properties.

CN201611000363.0 divulges a UV-curable covering for fiber optics finishing, which is prepared from the following basic materials partially by weight: ethoxylated trimethylolpropane triacrylate 20-30, cyclotrimethylolpropane methylated Aldehyde acrylate 30-41, ethoxy ethyl acrylate 10-15, photoinitiator 2959-2-4, pentaerythritol pentaacrylate 4-7, tripropylene glycol diacrylate 3-6, 3-Glycidyl ether oxypropyltrimethoxysilane 1-2, glycidyl neodecanoate 1-2, nano-attapulgite 12-15, methyl-(butylcarbamoyl)-2-benzimidazole Carbamate-1-2, additives 9-13. The thickness of the ultraviolet treatable coating of the development is modest, the firmness and durability of the finishing movie can be well balanced, the adhesive force is good as well as the chemical medium resistance efficiency is superb.

CN201910879900.0 discloses a 3D printing pure transparent as well as challenging material, which relates to the area of 3D printing innovation, which includes the complying with percents of basic materials: prepolymer: 30-50%, responsive diluent monomer: acryloyl morpholine (ACMO) 20-40%, cyclotrimethylolpropane formal acrylate (CTFA) 20-40%, photoinitiator: 1-hydroxycyclohexyl phenyl ketone (184) as well as 2,4,6-trimethyl Benzoyl-diphenylphosphine oxide (TPO) total 1-4%, ingredients: 0.01-0.2%, light stabilizer: 0.5-2%, plastic yellowing agent RQT-TS 0.001-0.05%. The 3D printing is pure and challenging material. Compared with other resins, the design published with this formula will not yellow for a long time. The version published with this formula can withstand a considerable amount of pressure without breaking. The version published with this formula The mechanical residential or commercial properties are not quickly impacted by light and environmental moisture. It is suitable for printing clear designs with printers in the 395-405nm band. The printed resin designs are pure and clear, non-yellowing, and also have great efficiency.
