But the Mannich base imparts a pronounced unpleasant amine odor to the material and causes the material to turn yellow over time
Since the Mannich base is not incorporated into the polymer upon curing, undesired migration effects and substrate discoloration may also occur

Abstract

The invention relates to a two-component composition, containing at least one silane-group-containing polymer that is liquid at room temperature, at least one epoxide liquid resin, at least one polyetheramine, and at least one aminosilane or mercaptosilane. The composition has low odor, cures quickly and without blistering at room temperature, and, when cured, forms a tough elastic material of high strength, high adhesive force, and good thermal resistance that has no tendency toward yellowing or substrate discoloration. The composition is excellently suitable as a tough elastic adhesive for structural adhesive joints in the field of construction and in industrial production.

Description

Technical field [0001] The present invention relates to a two-component composition curable at room temperature based on a combination of a silane group-containing polymer and an epoxy resin, and its use in particular as a viscoelastic adhesive. Background technique [0002] As adhesives for structural bonding, two-component polyurethane systems are known. The two-component polyurethane system cures quickly and forms a viscoelastic material with high strength, but in some cases contains isocyanates that are harmful to health and may form bubbles during curing. [0003] Also known are two-component epoxy resin adhesives. The two-component epoxy resin adhesive achieves extremely high strength, but is not viscoelastic but brittle and hardly stretchable, so it is not suitable for many structural bonding applications. [0004] Also known are curable materials based on silane-functional polymers. The curable material is usually formulated in a one-component form and crosslinked by react...
