Rheological Studies of UV - curable Materials
The challenge for studying fast changing systems with rheology such as UV initiated polymerization and crosslinking is multifold. These materials react within seconds and the moduli change over 2 to 3 decades. UV light must irradiate the sample homogeneously over a short time period and fast data acquisition is required to capture the modulus change during the reaction. An option for UV curing,...
متن کاملPreparation and Properties of UV curable urethane methacrylate oligomer
N,N-dihydroxyethyl methylacrylamide (DHEMAA), which is a methacrylate modified by diol, has been prepared by reaction of diethylanol amine with methyl methacrylate. UV curable urethane methacrylate oligomers have been synthesized by the reaction of a series of diol, triol, DHEMAA and HEMA with TDI or IPDI in two reaction orders. The first reaction style is the TDI or IPDI reacted with HEMA firs...
متن کاملUV-curable Encapsulants for LED
UV cured epoxy systems represent complementary technology to the established heat cured epoxy systems for coating, adhesion and encapsulation of electronic devices. The UV cured epoxy systems offer significant benefits in terms of fast cure and thus very short production cycle time; low stress and better colour due to room temperature cure; process wise no mix ratio problem or anhydride handlin...
متن کاملThermal Conductivity and Viscoelastic Properties of UV-curable Urethane Acrylate Reinforced with Modified Al2O3 Nanoparticles
In this study, UV-curable urethane acrylate UA synthesized and then characterized by FTIR and HNMR. For better dispersion of nanoparticles in polymeric matrix, nano Al2O3 was modified by silane coupling agent and then its nanocomposites were prepared. The characteristics of synthesized nanocomposites were analyzed by TGA, DMA and infrared thermography. The results signify that adding nano Al2O3...
متن کاملStudy the curing behavior and mechanical properties of Pigmented UV curable epoxy acrylate monomers
The formulations contained different acrylate monomer with different structure and functionalities and TiO2, were applied to obtain pigmented acrylic films by UV exposure. The conversion and mechanical characteristic were correlated. The results showed that there is a significant interaction between pigment, reactive diluents’ type and mechanical properties of coatings. It seems that cured film...
