The interfacial active agent of this invention copolymerizes with the polymerization characteristic resin matrix where the interfacial active agent is installed, becomes one one part of that matrix. Slow leaking out which passes the movement or the boundary in the matrix of the interfacial active ...
In this experimental study, we aimed to test our hypothesis that the use of cyanoacrylate gluing (application of an acrylic resin, a monomer of cyanoacrylate molecules, which rapidly polymerizes in the presence of water, forming long, strong chains and joining the bonded surfaces together) ...
THE INVENTION IS RELATED TO A GLUING AGENT FOR THE GLUING PROCESS OF MASSES AND SURFACES, WHICH IS COMPOSED OF A WATER DISPERSION OF COLOPHONY RESIN WITH STARCH AND A FORMALDEHYDE CONDENSATE OF NAFTALIN SULPHONIC ACID FOR THE PROCEDURE THIS AGENT, WHERE THE COLOPHONY RESIN IS MIXED WITH THE RES...

resin which differs from acrylic acid ester copolymer, by after the starting the measurement, filling up the below-mentioned formula (1) from 10 minutes to 2 hours, offers the gluing film for the semiconductor, regarding the semiconductor device where the semiconductor device is laminated to the ...
Thus, it is necessary to find a substitute for this traditional resin through an ecologically alternative based on safe use for humans, lower costs without the dependence on volatile prices of this commodity and, above all, with similar mechanical properties. The need for “green chemistry” has...
The actual process of using a resin to glue can optimize many shortcomings in the basic traditional process of welding a motor core. For example, the use of a resin for gluing can lead to a reduction in iron loss, improve rigidity, reduce processing times, and improve product quality. When...
the first component being in an amount from about 1-99 % by weight of the composition; and a second component of an ethylene and alpha -olefin copolymer, the alpha -olefin having 6 carbons, the second component being in an amount from about 99 % to about 1 % by weight of the composit...
