  • Aqueous pretreatment for bonded joints with increased heat stability
    Patent number: 11479676
    Abstract: An aqueous composition including: a) at least one epoxy silane containing at least one epoxy group and at least one hydrolysable group bound to Si, b) at least one non-ionic wetting agent and either c1) between 0.2 and 2 wt. % of at least one mercapto silane containing at least one mercapto group and at least one hydrolysable group bound to Si, and as many water-soluble acids as required for the pH of resulting composition to be between 1 and 6, on the condition that epoxy silane content amounts to between 0.2 and 1 wt. %, or c2) between 0.1 and 1 wt. % of a water-soluble organotitanate, in relation to entire weight of aqueous composition, and as many water-soluble bases as required for the pH of resulting composition to be between 8 and 14, on the condition that the epoxy silane content amounts to between 0.2 and 0.5 wt. %.
