Abstract: A silane of the formula (I) containing at least one aliphatic amidine group- or guanidine group-containing alkoxy group, to a method for producing same, to conversion products thereof, and to the use thereof as a catalyst in curable compositions, in particular based on silane group-containing polymers. The silane of the formula (I) is largely odorless and non-volatile at room temperature. The silane accelerates the hydrolysis and condensation reaction of silane groups very effectively without impairing the storage stability of silane group-containing polymers. Additionally, the silane is very tolerable in silane group-containing compositions, whereby such compositions are not prone to separate, migrate, or evaporate the catalyst.

Abstract: The invention relates to a composition comprising at least one organic polymer that contains silane groups and at least one catalyst of formula (I). The composition is low in emissions and low-odour, has a good shelf-life, cures rapidly to form a mechanically high-quality, durable material with a very low propensity for migration-related defects such as exudation or dirt retention by the substrate. The composition is particularly suitable for use as an adhesive, sealant or coating.

Abstract: Curable compositions include at least one organic polymer which contains silane groups and/or isocyanate groups, at least one compound which contains acetal groups and has a molecular weight of at least 280 g/mol, and at least one basic catalyst. The composition is particularly storage-stable and can be readily processed. Using moisture the composition cures rapidly, and with very little residual tackiness, to form a resilient material that has good adhesive and mechanical properties, in particular a high level of malleability and elasticity, is heat resistant and exhibits hardly any odour formation or migration effects. In particular, the composition has very consistent product properties during storage in respect of viscosity, curing rate and odour.

Abstract: The present invention relates to an amidine of the formula (I) and its use as a catalyst for crosslinking a curable composition. The amidine of the formula (I) contains at least one aliphatic amidine group. It is substantially odorless and nonvolatile at room temperature and accelerates the crosslinking of curable compositions very efficiently, without impairing the storage stability of the compositions. It is particularly suitable for compositions based on polymers containing silane groups, with which it is compatible, as a result of which such compositions do not have a tendency to separation or migration or evaporation of the catalyst.

Abstract: The use of an amidine of formula (I) and/or a conversion product thereof as a catalyst for the crosslinking of a composition based on silane group-containing polymers. The amidine of formula (I) and the conversion products thereof are essentially odourless at room temperature and non-volatile and accelerate the crosslinking of the composition very well without impairing the storage stability of the composition, and are very compatible in the composition. As a result, the compositions do not have a tendency to separate, migrate or evaporate the catalyst.

Abstract: A moisture-curing, condensation-crosslinking silicone composition that can be used as elastic adhesives and sealants. The silicone composition shows homogeneous depth curing, such that it cures through even under movement without forming cracks. The silicone composition contains at least one polyorganosiloxane having Si(OR3)3 end groups, at least one condensation catalyst and at least one crosslinker having hydrolyzable radicals, characterized in that the polymer end groups Si(OR3) have a reaction rate in the crosslinking reaction that is at least equal to and preferably higher than the hydrolyzable radicals of the at least one crosslinker.

Abstract: A guanidine of the formula (I) and to the use thereof as catalyst for the crosslinking of a functional compound, especially a polymer having silane groups. The guanidine of the formula (I) described is preparable in a simple method via a polyfunctional carbodiimide adduct from the readily available raw materials, and is largely odorless at room temperature and of low toxicity. In spite of its comparatively high molecular weight, it accelerates the crosslinking of functional compounds surprisingly well, and such compositions do not have a tendency to migration-related defects such as separation, exudation or substrate soiling.

Abstract: A compound containing at least one hexahydrotriazine unit of formula (I) having at least one amidine or guanidine group and to the use thereof as a catalyst for the crosslinking of a functional compound, in particular a polymer including silane groups. The compound contains at least one hexahydrotriazine unit of formula (I) is producible in a simple process from readily available feedstocks, odorless at room temperature, non-volatile and largely non-toxic. The compound accelerates the crosslinking of functional polymers surprisingly well and by simple variation of the substituents is variable such that it has very good compatibility in different polymers as a result of which such compositions do not have a propensity for migration-based defects such as separation, exudation or substrate contamination.
