A-12石材滲透劑是一種有著極強滲透性的石材防護材料。經過這種材料處理后的石材能夠有效的防止石材受到水和其它液體污染的損害后出現水斑、黃變、返堿、風化漲裂現象，也使得石材日常保養更容易，更能長久保持石材自然美麗。 產品特點： ★ 極強的滲透性和優秀的防水性、耐堿性。 ★ 耐候性較好，紫外線穩定，防護壽命長。適合對室內外石材表面進行防護處理。 ★ 小分子結構容易穿透石材表面與其發生化學鍵合形成持久有效防水層。 ★ 深層滲透，石材表面的日常磨擦和清洗不會降低防護效果。 ★ 正確使用不會改變石材的顏色，處理后的石材仍保持其透氣性。 ★ 適合室內外花崗石、大理石、沙巖和瓷磚等建材的防護處理。 ※產品安全性依據歐洲 European Commission Directive 1999/45/EC(Article 3 [3]). ※產品性能符合 NCHRP224 和 ASTM standard標準. A-12 Impregnating Protection is a kind of stone protecting material with extremely strong permeability. It can effectively prevent stone from damage by water or other liquids. It prevents the stone turning yellow, becoming alkalized, weathering, splitting, appearing water-stained or acquiring other blemishes that can be difficult to clean out. It makes the daily maintenance of the stone easier and preserves its natural beauty longer. CHARACTERISTICS ★ Suitable for the surface of stone inside or outside of the room. ★ Waterproof is good. The ultraviolet ray is steady. It can increase the protective life of the stone. ★ The tiny molecular structure makes it easy for A-12 to pierce through the stone surface and cause a chemical reaction with it to form a lasting and effective protective barrier against water. ★ Permeates deeply. Ordinary scrubbing or washing will not reduce the effect of protection . ★ The treated stone still breathes. ※ Product safety according to European Commission Directive 1999/45/EC(Article 3[3]). ※ Product function measure up NCHRP224 and ASTM standard.
