STABILIZATION OF LIQUID RADIATION-CURABLE COMPOSITIONS AGAINST UNDESIRED PREMATURE POLYMERIZATION |
摘要 |
The invention relates to a process for stabilizing a liquid radiation-curable composition comprising a cationically polymerizable compound and a photoinitiator for cationic polymerization against premature commencement of the polymerization, in which a basic ion exchanger is brought into contact with the composition, at least for a certain time. The ion exchanger is preferably removed before commencement of the radiation curing, at least from the part of the radiation-sensitive composition which comes into contact with the radiation. The process is particularly suitable for stabilizing stereolithography baths in extended use against an undesired increase in viscosity.
