UV-curable formulations were prepared by mixing UA/HB-PEs as binder component with n-NVP, HDDA
, and TPGDA as reactive diluents to adjust the viscosity of coating formulations and enable solubilization of the photoinitiator.
The monomer, HDDA
, was supplied by Guangzhou Xinri Chemical Technology Co., China.
Phthalazinone-containing epoxy methacrylate (EMA-P) was mixed with reactive diluents composed of 10% TMPTA, 20% HDDA
, 3% HMPP photoinitiator, and silane coupling agent KH-570, with constant stirring.
also can increase adhesion to soluble plastics as well.
Polyfunctional monomer (1,6-hexanediol diarylate, HDDA
) was purchased from Tianjintianjiao Chemical, China.
The output of TMPTA and TPGDA was 15,480 tons and 16,250 tons, respectively, and HDDA
and DPGDA were both more than 3,000 tons.
Now China can produce generally used monomer products such as TEGDA, DEGDA, PETA, TMPTA, TPGDA, NPGDA, HDDA
, PDDA, EOTMPTA and others.
A system consisting of dimethyl sulfoxide (DMSO) and 1,6-hexanediol diacrylate (HDDA
) with diethyl phthalate (DEP) and [(NH4).sub.2][S.sub.2][O.sub.8] as the thermal initiator was used and by varying the initiator concentration, different velocities were obtained.
HPA and 1,6-Hexancdiol diacrylate (HDDA
) were supplied by Baorun Chemistry Co., Shanghai, China.
TMPTA and 1,6-hexanediol diacrylate (HDDA
)were purchased from Eternal Chemical Company (Taiwan, China).
The newest offerings from BYK-Chemie include Nanobyk-3602, which is based on alumina nanoparticles in hexandiol diacrylate (HDDA
); Nanobyk-3610, which contains surface-modified alumina nanoparticles in methoxypropylacetate (PMA); and Nanobyk-3650, which is composed of surface-modified silica nanoparticles in PMA.
Available dispersed in DPGDA, HDDA
, TPGDA, plus custom bases.
