A-12石材渗透剂是一种有着极强渗透性的石材防护材料。经过这种材料处理后的石材能够有效的防止石材受到水和其它液体污染的损害后出现水斑、黄变、返碱、风化涨裂现象，也使得石材日常保养更容易，更能长久保持石材自然美丽。 产品特点： ★ 极强的渗透性和优秀的防水性、耐碱性。 ★ 耐候性较好，紫外线稳定，防护寿命长。适合对室内外石材表面进行防护处理。 ★ 小分子结构容易穿透石材表面与其发生化学键合形成持久有效防水层。 ★ 深层渗透，石材表面的日常磨擦和清洗不会降低防护效果。 ★ 正确使用不会改变石材的颜色，处理后的石材仍保持其透气性。 ★ 适合室内外花岗石、大理石、沙岩和瓷砖等建材的防护处理。 ※产品安全性依据欧洲 European Commission Directive 1999/45/EC(Article 3 [3]). ※产品性能符合 NCHRP224 和 ASTM standard标准. 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.
