The present disclosure relates to silane-crosslinking adhesives or sealants comprising a) at least one polymer of the general formula (I) in which R is a monovalent to tetravalent hydrocarbon radical, R1 is an alkyl radical having 1 to 8 C atoms, R2 is an alkyl or alkoxy radical having 1 to 8 C atoms, and A is a carboxyl, carbamate, carbonate, ureido, urethane or sulfonate linker or an oxygen atom, x is 1 to 8, and n is 1 to 4, and b) at least one adhesion promoter, dryer and/or reactive diluent. The adhesion promoters, dryers, and/or reactive diluents are ethoxy-functional α-silanes of the general formula (II) in which R3 is an organic radical attached to the methylene group via a heteroatom, and R4 is an alkyl radical having 1 to 8 C atoms or an ethoxy radical. The disclosure further relates to a process for producing the adhesives or sealants, and also to their use.
摘要:
A nozzle for the discharge of a flowable substances, for example adhesive or sealing compositions, having a discharge orifice with a variable geometry. The adjustable nozzle permits the user to select the optimal discharge profile suited to a particular application of the composition being discharged.
摘要:
Two-sided adhesive strips for detachable bonding without residue or damage. The strips include a foam backing fixed to at least one essentially non-elastic layer. The bond is detached by rotative or shear force breaking the foam backing in two parts that remain attached to the bonded surfaces. The residues are removable by pulling at an angle greater than 45° from the bond plane. The strips have high load capacity and bearing strength.

The invention relates to a method for dyeing keratin fibers, especially human hair. The inventive method comprises the following steps: optionally applying a pretreatment agent M1 to the fiber, using a dye M2 on the fiber which is optionally mixed immediately before application to the fiber from a component M2a, containing at least one oxidative dye pre-product of the developer type and/or an indole and/or indole derivative and a component M2b, containing an oxidative dye and/or an enzyme. If desired, a third agent M3 is added to the individual agents M2a or M2b before mixing them or to the mixture M2, and said dye M2 is rinsed from the fiber after a period of 5–10 minutes. At least one of the agents M1, M2a, M2b or M3 contains a compound from the vitamin B6 group. The invention further relates to hair pretreatment agents, to agents for dyeing keratin fibers, to their packing in corresponding kits and to the use thereof. The inventive compounds of the vitamin B6 group and their physiologically acceptable salts are useful as coupling components in the production of oxidative dyes that contain conventional developer and/or coupling compounds and/or indole and/or indole derivatives in a substrate appropriate for dyeing. The inventive compounds are further useful as active substances that improve the hair structure.
