The invention relates to a crosslinkable one-component lamination adhesive containing a) 25 to 80 wt % of polyester prepolymers, polyether prepolymers, and/or polyurethane prepolymers that comprise at least two crosslinkable silane groups, b) 75 to 20 wt % organic solvent having a boiling point of up to 130&#xb0; C., c) 0 to 15 wt % additives, the prepolymer having a molecular weight from 2000 to 30,000 g/mol, wherein the viscosity of the adhesive is between 50 and 20,000 mPas (per DIN ISO 2555) measured at 15 to 45&#xb0; C., and the crosslinked adhesive has a glass transition temperature from &#x2212;10 to 30&#xb0; C.

Silane cross-linked 1-component lamination adhesive

The invention aims to allow a curable composition to have an extended working phase followed by a short time period in which said compound becomes fully cured. This is achieved by the provision of a curable composition comprising the following components: a) at least one polyether and/or at least one polyacrylic acid ester with at least one reactive silyl group as an end-group; b) at least one organotin compound; and c) at least one compound that does not contain any tin or silicon atoms and that has at least two functional groups. Said groups are selected from the following: carboxy, carbonyl or hydroxy groups, or nitrogen atoms that are part of a ring system with aromatic character. In addition, the invention relates to a method for producing such a composition, and to the use thereof as an adhesive, a sealant or as a coating material.

Moisture-curing formulations with time-modified phases

A method for producing colored layers on zinc, aluminum, magnesium or alloy surfaces. The surfaces are brought into contact with an aqueous treatment solution which is devoid of chrome, said solution containing, in total, 3-35 g/l persulfate ions and/or peroxodisulfate ions and not more than 10 g/l ammonia or ammonium ions, it has a pH value in the region of between 10-12 and a temperature in the range of between 30-80&#xb0; C. The surfaces are brought into contact with the treatment solution for a period in the region of 0.5-5 minutes and optionally, they are covered with a coating based on organic polymers. The invention further relates to metal parts treated according to said method.

The present invention relates to support-fixed bleaching catalyst(s)suitable or the catalysis of peroxide compounds, characterized in that the support-fixed bleaching catalyst(s) is/are covalently bonded to a support by means of at least one organic ligand of the bleaching catalyst. The bleaching catalyst(s) form(s) a complex with at least on transition metal. The invention further relates to support-fixed bleaching catalysts for the catalysis of peroxide compounds, where at least one ligand, covalently bonded to a support, is a transition-metal-free ligand, which chelates with transition metal, derived from another source, preferably from the bleaching composition and/or added water and thus forms the complex with a transition metal.
