The present invention relates to a polyurethane-based two-component adhesive composition. The invention also relates to the manufacture of membrane-type filtration cartridges using the two-component adhesive composition according to the invention.

The present invention is a polyester composition for a masterbatch, which comprises a polyester, a magnesium compound, an alkali metal compound and a phosphorus compound, wherein magnesium atoms, alkali metal atoms and phosphorus atoms are contained in amounts of 400 to 2700 ppm by mass, 40 to 270 ppm by mass and 200 to 1700 ppm by mass, respectively, in the polyester composition, the melt resistivity of the polyester composition is 0.00510.sup.8 to 0.0510.sup.8 .Math.cm, and few contaminant particles are observed in the polyester composition under specified conditions. The polyester composition for a masterbatch has a satisfactorily low melt resistivity, contains few contaminant particles, and has an excellent color hue and excellent thermal stability.

A renewable chemical composition is disclosed for use in a variety of industrial applications. The renewable chemical composition may be reacted with an isocyanate to produce a urethane material. The renewable chemical composition has aromatic groups. The suitability of this material for use in a variety of applications can be adjusted by modifying the acid number, the hydroxyl number, the viscosity, the glass transition temperature, the % solids, the softening point, and other properties. The chemical reactivity and properties can be modified based on processing conditions and temperature as well as the source of renewable raw material. The lignin used in these formulations may be from pulp and paper processing such as semi-mechanical processing, soda processing, kraft processing, or biomass processing, or a by-product of ethanol production. The novel biobased polyurethane formulations range in firmness from flexible to semi-rigid to rigid and are useful in large volume polyurethane applications.

A process and composition is described for the inclusion of polyether polyols in concentrations greater than 10% loading on the B-side formulation with a catalyst package less than 1% loading on the B-side formulation. In one specific example, the use of glycerin as a fluorine ion scavenger is utilized to improve performance of the polyurethane systems through a twelve-month shelf life.

Poly(meth)acrylate impact modifiers having at least one multiphase alkyl (meth)acrylate emulsion polymer with at least one multivalent metal ion, and a defined amount of alkali metal ions improve the optical properties of moulding compositions produced thereof. One improved property is a high transparency after hot water storage. A method for producing the poly(meth)acrylate impact modifiers include the preparation of at least one multiphase alkyl (meth)acrylate polymer via emulsion polymerization, the coagulation and mechanical dewatering of the obtained latex.

A point-of-sale custom color system for tinting base paints and stains includes an array of water-only fluid colorants, including at least white, green, blue and red water-only colorants, which can be used to tint water-borne paints and stains. When tinting solvent-borne base paints or stains, at least one siccative is added to the solvent-borne base paint or stains at the point-of sale and a synergist containing one or more surfactants and optional dispersing agents or optional cosolvents is also added to or is a part of the solvent-borne base paint or stains. Collectively, the siccative and synergist enable effective tinting using the water-only colorants and suitable drying characteristics of the solvent-borne paint or stain.
