| abstract |
The invention relates to a single-component sealant or adhesive composition, comprising: a) an aqueous polymer dispersion comprising water and at least one water- dispersed polymer P having a median particle size D50 of less than 150 nm, b) at least one water-dispersed or water-dissolved epoxy- or carbodiimide- functional cross-linker C, wherein the pH of the composition is adjusted in the range of 7 to 12, and wherein said at least one water-dispersed polymer P is comprised in the composition with an amount of at least 45 wt.-%, based on the total composition, and wherein said epoxy- or carbodiimide-functional cross-linker C is comprised in the composition with an amount of between 0.5 and 5 wt.-%, based on the total composition. The composition is highly suitable as sealant or adhesive and shows excellent optical properties regarding transparency or translucency, as well as improved resistance e.g. towards water immersion. |
