chemicals for Alkali-resistance of mesh

The most important indicator of fiberglass mesh is alkali resistance. Alkali resistance of mesh is its ability to maintain its tensile strength properties in an alkaline environment. The fact is that plaster mixtures and mortars based on cement have an aggressive alkaline environment with a pH factor > 11. In such an environment, the tensile strength of mesh decreases, while for cheap, mainly Chinese, it drops In conclusion, we would like to give advice: strengthen the facades only with high-quality fiberglass mesh.

This indicator in the normal (as-delivered) state should be at least 30 N/mm on the warp yarn direction and within 40 N/mm on the weft yarn direction. Weft yarns are almost always stronger than the warp yarns; therefore, when testing mesh, some importers indicate in the Product Quality Certificate only one indicator of tensile strength, which does not reflect the real picture. The tensile strength of the fiberglass mesh is over 32 N/mm on the warp yarn direction and more than 44 N/mm on the weft yarn direction. This data complies with European quality standards!

Ruico have formulated a series of SBR/ACRYLIC binder for fiberglass mesh coating, supply to Russia, Romania, Moldova, Thailand, India, China, Hungary, Slovenia etc.
