RECYCLING OF CURED POLYSULFIDE AND/OR POLYMERCAPTAN ADHESIVES/SEALANTS |
摘要 |
<p>The invention concerns a process for recycling hardened or partially hardened polysulphide and/or polymercaptan compositions. Processing is carried out in a non-volatile liquid, with the addition of a depolymerization agent, preferably a sulphurous vulcanization accelerator known from rubber technology. The depolymerisate can be added in high proportions to the hardener component of two-component polysulphide and/or polymercaptan adhesives, sealants or coating materials without substantially modifying its hardening characteristics or properties concerning stability during storage.</p> |
