Abstract (en)
[origin: DE19856254A1] The invention relates to an adhesive powder for assembling flat, non-porous or porous substrates, whereby, in a first step, the adhesive powder is applied onto a first substrate, and an intermediate product is produced which is non-adherent at room temperature and which is stabile in storage. The first substrate is joined with a second substrate in a second step by applying an increased temperature and pressure and while using a combination of the following components: i) a thermoplastic polymer with a proportion ranging from 25 to 95 wt. %, and ii) at least one epoxy resin which is solid at room temperature and which has a proportion ranging from 5 to 75 wt. %, and optionally iii) at least one prepolymer which is comprised of epoxy resins and polyamines, is solid at room temperature, and which has a proportion of no more than 25 wt. %. A physical binding occurs when the adhesive powder is applied to the first substrate in the first step, and both substrates are joined to one another in the second step by a chemical cross linking or post-cross linking of the powder constituents and by a subsequent cooling.
