摘要:
A method of controlling the rheology of a sealing glass paste which comprises incorporating a fine inorganic powder in the paste as a mill addition to impart a steep rheology curve to the paste so that the paste resists flow while at rest, but flows readily when shear stress is applied, the amount of inorganic powder incorporated being not over about 10% by weight.

A method of producing a formable mixture involves combining a powder material, and a plurality of gel-forming polymers, wherein at least one gel-forming polymer is a proton donor, and at least one gel forming polymer is a proton acceptor. A method of making a monolithic structure involves producing a formable mixture of powder material which can be ceramic, metal, glass, glass ceramic, molecular sieve and combinations thereof, a plurality of gel-forming polymers as described above, extruding the mixture to form a green monolithic structure, and drying and firing the green structure.
摘要:
Hydrophobic polymer surfaces whose level of protein binding is less than about 50-80 ng/cm2 are achieved by: (1) applying a coating solution composed of a solvent and a non-ionic surfactant having a HLB number of less than 5 to the surface; and (2) drying the surface to remove the solvent and thereby bring the surfactant into direct contact with the hydrophobic polymer. The combination of a low HLB number and the drying step have been found to produce low binding surfaces which can withstand multiple washes with water and/or protein-containing solutions. Alternatively, the low binding surfaces can be produced by applying the non-ionic surfactant to the mold surfaces which contact molten polymer and form the polymer into a desired shape, e.g., into a multi-well plate, a pipette tip, or the like. Further, the low binding surfaces may be produced by incorporating non-soluble, non-ionic surfactants having an HLB number of less than or equal to 10 into a polymer blend prior to molding the article.

Hydrophobic polymer surfaces whose level of protein binding is less than about 50-80 ng/cm2 are achieved by: (1) applying to a hydrophobic polymer surface a coating solution composed of a solvent and a non-ionic surfactant having a HLB number of less than 5 and at least one hydrophilic element which can extend into an aqueous solution; and (2) drying the surface to remove the solvent and thereby bring the surfactant into direct contact with the hydrophobic polymer. The combination of a low HLB number and the drying step have been found to produce low binding surfaces which can withstand multiple washes with water and/or protein-containing solutions.

Molding uses shear condition that cause the surfactant to move to the surface of a polymer product formed by the molding such that a hydrophilic part of the surfactant extends from the surface to provide a surface having low binding for proteins.
