Abstract
The invention relates to a process for hot application of an adhesive composition (80) on a support (96), by means of a system comprising: a nozzle (50) for applying the adhesive composition (80), a line (88) for supplying the nozzle (50) with the adhesive composition (80) to be applied in fluid form, a mixer (30) positioned in the line (88) for the homogeneous mixture of the main components of the adhesive composition before its application; the applied adhesive composition (80) including as main components: a silylated prepolymer, a compatible tackifying resin; the adhesive composition comprising a cross-linking catalyst; the process comprising: supplying the line (88) with the silylated prepolymer separated from the cross-linking catalyst, the mixing of the cross-linking catalyst with the main components by means of the mixer (30), the hot application of the mixed adhesive composition (80) onto a support (96).
