| Résumé : |
A novel silane-terminated binder can provide cement-bound floors with highly effective protection from stains. 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 JÃ nkmajtis, Hungary
- Fig. 7. Production hall at the Agricolae Kft plant following a second coat of the impregnation agent. The surface is now uniformly glossy |
