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.

The present invention relates to a curable bicyclic compound derived from biomass, solvent-free curable composition and a method for preparing thereof. The curable compound derived from biomass according to the invention comprises a bicycle structure, to which one of two epoxide functional groups are bonded.
The present invention relates to an amine of the formula (I) which is an adduct of 1,2-propylenediamine with an aryl monoglycidyl ether, to the use thereof as part of a hardener for epoxy resins, and to epoxy resin compositions obtained therewith. The amine of the formula (I) is preparable in a simple process in high purity, is of very low viscosity and is especially suitable for the curing of epoxy resins. It allows low-emission epoxy resin compositions which have good workability and which cure even under cold and damp conditions, quickly and without blushing effects, to form very hard products of high surface quality that display virtually no yellowing on exposure to light.
An amine of formula (I) which is particularly suitable for use as a curing agent for epoxy resins. The amine of formula (I) is devoid of non-incorporable toxic phenols, and is low-viscosity and pale in colour. It allows the production of easily-workable, low-emission or emission-free epoxy resin products which cure rapidly even at relatively low ambient temperatures thus obtaining a high degree of hardness and a nice surface with hardly any yellowing. This is particularly suited to use in floor or top coatings.
