The invention relates to bonding agent compositions containing at least one bonding agent comprising an isocyanate group. This specific bonding agent is produced from a mixture of a polyester resin A, at least one monomer diphenylmethane-diisocyanate, and at least one polyisocyanate B, the monomer ...
This specific binder is prepared from a mixture of a polyester resin A, at least one monomeric diphenylmethane diisocyanate, and at least one polyisocyanate B, where the proportion of monomeric MDI is 鈮 2% by weight of the overall composition. Such adhesion promoter compositions are particularly ...

CONSTITUTION: A functio...
Mesoporous block copolymer nanoparticles with tailored structures by hydrogen-bonding-assisted self-assembly. A simple, yet robust route to prepare polymer nanoparticles with tunable internal structures through supramolecular assembly within emulsion droplets is pr... R Deng,S Liu,J Li,... - 《...
condensate, but the coupling agents inside the PDMS do not. The different hydrolysis kinetics across the interface impedes bonding. In the limiting case, no bonding is possible if all the coupling agents in the hydrogel have condensated before one single coupling agent in the elastomer has ...
where δd is the dispersion term, δp is the polar term, and δh is the hydrogen bonding term. 3.1.1.5 Solvent Interaction and Solubility Parameters It was shown in Section 3.1.1.4 that the interaction parameter has both entropic and enthalpic contributions. This is shown in Eq. (3.33), ...
A network may be formed by the reaction of monomer or prepolymer molecules to give a covalent network1 or by the intermolecular association of linear or branched polymers, commonly through hydrogen bonding, to give a physical network.2,3 In addition, some network structures, such as thermoplastic...
The synthetic polymer silicone was originally produced for use as a sealant or bonding agent. It is an elastomere, which is chemically inert, not degradable by UV light and thermally stable. The rapidly expanding market for construction membranes encouraged the increasing use of silicone for coating...
Effect of in-situ bonding system and surface modification of montmorillonite on the properties of butyl rubber/MMT composites Isobutylene–isoprene rubber (IIR)/nanoclay composites were prepared by solution intercalation method. Cloisite Na+ montmorillonite and organo-modified mon... SF Halim,SN Lawandy...
Bonding, flowable, and hybrid restorative composites incorporating the nanoparticles were tested after being cured by light initiation. Interestingly, although the nanoparticles were incorporated at a low concentration, a strong antibacterial activity was evident upon contact with bacteria without leach-out ...
