Process for hot application of a silylated adhesive composition

A process for hot application of an adhesive composition on a support comprising employing a hot application system comprising:

• an application nozzle applying the adhesive composition,
• a supply line supplying the application nozzle with the adhesive composition to be applied in fluid form,
• a dynamic mixer positioned in the supply line homogeneously mixing main components of the adhesive composition before its application;
• the applied adhesive composition including as main components:
• from 20% to 85% by weight of silylated pre-polymer,
• from 15 to 80% by weight of compatible tackifying resin;
• the adhesive composition further comprising from 0.01 to 3% by weight of cross-linking catalyst;
• the process comprising:
• supplying the supply line with said at least silylated prepolymer, separate from the cross-linking catalyst,
• mixing the cross-linking catalyst with the main components in the mixer,
• hot application of the mixed adhesive composition on a support by the application nozzle,
• wherein the conversion rate of the cross-linking reaction for the adhesive composition in the hot application system is less than or equal to 30%.
