The binder can be readily applied as a one-component impregnation system. Its performance has been verified in practical tests. Note de contenu : - New binder offers past, effective impregnation - Safe and simple to formulate and process - Application and curing parameters - Stain resistance is excellent - Surface colour is enhanced by clear coats - Practical value confirmed in an industrial plant - Project preparation and implementation - Efficient floor protection, with wide application - Table : Solvent-free reference formulation for transparent concrete impregnation - Fig. 1. Structure of an α-dimethoxysilane-terminated polyether. The two silane termini are each bound to a polyether backbone via a methylene group and a urethane unit - Fig. 2. Stain test : twenty substances were tested, including salt water, red wine, cola, mustard, ketchup and used oil - Fig. 3. Results of the comparison test on cementitious test plates. Only three stains cannot be removed from th eplate impregnated with the alpha-silane system - Fig. 4. The impregnation noticeably intensifies colour - Fig. 5. The material removed by abrasion from concrete test plates fell from 40 grams to 3 grams - Fig. 6. The diluted impregnation agent was applied to the sanded-down concrete floor of a production hall at the Agricolae Kft. fruit preserves plant in Jànkmajtis, Hungary - Fig. 7. Production hall at the Agricolae Kft plant following a second coat of the impregnation agent. The surface is now uniformly glossy En ligne : https://drive.google.com/file/d/1AwdbCKcuC_riajtgCezKAT2MPilIzoz6/view?usp=drive [...] Format de la ressource électronique : Pdf Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=30498 [article]
