Abstract:
A two-component composition is based on silane-functional polymers, especially silane-functional polymers with high reactivity. Such a composition shows long shelf life without the requirement of expensive stabilizers and is suitable to be used as a low E-modulus joint sealant offering excellent durability in high movement joints.

Claim (Index 1):
Two-component composition comprising\n a) a first component A, comprising\n between 50% and 100% by weight of at least one silane-functional polymer P selected from formula (I), (II), and/or (III) \n wherein radicals R 1  and R 2  independently represent a linear or branched monovalent hydrocarbon radical having 1 to 10 carbon atoms; radical R 3  represents a polyether or poly(meth)acrylate polymer after removal of p silane groups; radical R 4  represents a linear or branched divalent hydrocarbon radical having 1 to 6 carbon atoms and optionally containing one or more heteroatoms; radical R 5  represents a dialkyl succinate radical; radical R 6  represents a divalent aliphatic hydrocarbon radical having 1 to 15 carbon atoms; radical R 7  represents a hydroxyl-terminated polyether or polyurethane polymer after removal of p hydroxyl groups; radical R 8  represents a divalent linear, branched, or cyclic hydrocarbon radical having 1 to 15 carbon atoms and optionally containing heteroatoms; n represents an integer having a value of 2 or 3; m represents an integer having a value of 3-n; p represents an integer having a value of at least 2; and between 0% and 50% by weight of at least one plasticizer; and between 0% and 10% by weight of at least one organosilane OS; and between 0% and 5% by weight of at least one drying agent; wherein component A does not contain filler and component A is essentially free of catalyst for catalyzing hydrolysis and/or condensation of organosilanes and wherein the amounts of all individual components comprised in component A are adjusted such that their sum equals 100%; and b) a second component B, comprising\n between 0.05% and 4% by weight of a catalyst for catalyzing hydrolysis and/or condensation of organosilanes; and \n between 25% and 75% by weight of at least one filler; and \n between 0% and 60% by weight of at least one plasticizer; and \n between 0% and 0.5% of at least one stabilizer; \n wherein the amounts of all individual components comprised in component B are adjusted such that their sum equals 100%; \n wherein the mixing ratio by weight of component A to component B is between 1:1 and 1:5.
