Embodiment Construction

[0266] Working example:

[0267] The following examples were carried out using the following curable materials comprising silyl polyethers 1 containing trialkoxysilyl groups according to the not yet published specification DE 10 2008 000360.3 according to 3-glycidyloxypropyl Triethoxysilane (Dynasylan GLYEO, DMC-catalyzed alkoxylation protocol from Evonik Degussa GmbH). PO stands for propylene oxide.

[0268] To determine polydispersity and average molar mass, GPC determinations were performed under the following conditions: column combination SDV 1000 / 10 000 (length 65cm), temperature 30°C, THF as mobile phase, flow rate 1ml / min, sample concentration 10g / l, RI detector, contrast polypropylene glycol standard evaluation.

[0269] The viscosity was measured at 25° C. according to the method of DIN 53019 using a Brookfield rotational viscometer (type LVT).

[0270] The percentage NCO content is determined according to DIN EN ISO 11909 by back titration with 0.1 molar hydro...

Abstract

Curable material comprising silylated polymers containing urethane groups, and use thereof in sealants, adhesives, binders and / or surface modifiers.

Description

technical field [0001] The present invention relates to the use of novel curable materials comprising reaction products containing urethane groups and obtainable from silyl polyethers and compounds containing isocyanate groups for surface modification and surface Coatings, for the preparation of sealants, adhesives and adhesives, and for polyurethane systems, the invention also relates to a method for the preparation of said curable material. Background technique [0002] To those skilled in the art, there are many known types of curable materials or reactive prepolymers tailored to the particular field of application. In all cases, the compound needs to contain reactive, curable and / or crosslinkable functional groups, for example, epoxy, amino, hydroxyl, isocyanate, acrylate, vinyl, allyl or silyl group. Among these very different types of prepolymers, moisture-curing systems with silyl groups and / or isocyanate groups are of considerable economic importance. [0003] Amo...
