摘要:
The present invention relates to curable, liquid, adhesive compositions comprising polyamideimide resins for use in bonding layers of material in metal clad laminate materials for electronic components, such as flexible circuit boards. In particular, the invention relates to liquid adhesive compositions comprising polyamideimides having a terminal isocyanate group blocked by a thermally-dissociatable isocyanate-blocking group and the use of such compositions in preparation of flexible electronic components.

Provided are energy curable high-stretch inks and coatings for heat transfer labels. The inks and coatings include monofunctional monomers/oligomers, thermoplastic inert resins, and zero or a limited amount of multifunctional monomers/oligomers and exhibit good stretchability and surface resistance, such as scratch resistance and solvent (water, oil) resistance. Also provided are methods of using the high stretch inks in heat-transfer label (HTL) applications.

Techniques disclosed herein include systems and methods for automated control of lighting systems. Such lighting system controllers can provide a range of control without requiring substantial programming, and that are compatible with existing, conventional, and new lighting systems. Such controllers include devices that can provide several features including network connectivity, a range of output levels, automated demand response control to manage electricity consumption, automated response to secondary sensor input (such as from photoreceptors and motion detectors), and generation of statistics showing power savings. A lighting controller polls a remote server or associated sensors to gather data relating to light output levels, determines to modify light output of corresponding light fixtures, and then transmits radio frequency signals over electrical power lines to light fixtures to modify light output.

摘要:
A powder coating composition comprising a powdered solid ethylenically unsaturated material having a melting point from 60° to 120° C. obtained by reacting a polyisocyanate with an at least stochiometric amount of an alcoholic component comprising: at least a monovalent alcohol, a part of which bears an ethylenic unsaturation derived from acrylic acid or methacrylic acid, and optionally at least a monomeric polyol. This composition is useful for coating substrates.
摘要:
An energy curable inkjet ink includes a nitroxy inhibitor, a compound having an ethylenic unsaturated bond, a photoinitiator, a coloring agent, and a stray light resistance index of at least 7. A method of preparing an energy curable inkjet ink with stray light resistance includes providing a nitroxy inhibitor; providing a mixture of a compound having an ethylenic unsaturated bond, and a photoinitiator, and a coloring agent; combining the nitroxy inhibitor and the mixture to obtain the energy curable inkjet ink and thereby to increase a stray light resistance index of the energy curable inkjet ink to at least 7.
