50results about How to "Increased cross-linking rate" patented technology

Focused acoustic treatment of samples including a target biomolecule, such as cfDNA, may aid in the recovery of the biomolecule from a sample. cfDNA in a sample, whether chemically stabilized or not, may be linked or otherwise bound to histones or other proteins, e.g., by hydrogen bonds of histones or chaperone proteins to DNA and/or covalent crosslinks of such proteins to the DNA. Focused acoustic energy may remove or disrupt such links, aiding in isolation of the cfDNA from the sample.

The invention discloses aziridine crosslinked and solidified acrylate resin two-component water-based automobile coating and a preparation method thereof. Water-dispersed acrylate resin used for preparing the two-component water-based coating is prepared by initiating polymerization by virtue of a free radial initiator in an organic cosolvent by a mixture of a monomer component A, a monomer component B and a monomer component C, and then an amine neutralizer is added for neutralization to form aqueous dispersion. The aziridine crosslinked acrylate resin two-component water-based automobile coating is formed by mixing water-dispersed acrylate resin, an aziridine crosslinking agent and other auxiliaries, a paint film formed after spraying and solidification has high gloss, high hardness, high impact resistance and excellent water resistance, interlayer bonding is tight, firm adhesion on a substrate is achieved, and operating requirements of automobile coating are met.

The present invention relates to moisture-reactive hot-melt adhesive compounds, comprising at least one polyurethane polymer P which is solid at room temperature and which has isocyanate groups, at least one polyaldimine ALD of the formula (Ia) or (Ib), and at least one acid K in the form of an organic monocarbon acid, or dicarbon acid, or an organic monosulphonic acid, or disulphonic acid, or a compound which can be hydrolyzed to give one of these acids. These hot-melt adhesive compounds cure without bubbles and exhibit exceptionally quick crosslinking speed and good strength after crosslinking.
