pva 1788/ 2488, PVA 1799/ 2499 powder divided into 99 series and 88 series according to the difference of polymerization and alcoholysis degree.The dry mortar chemical additives PVA developed by us is PVA1799-2499 series and PVA1788-2488 series hybrid products, appearance in granular and powdered mixture. It combined the advantages of the series 99 and 88, overcome original disadvantage , increased the bond strength and thermal stability, accelerated dissolution in lower temperature. It greatly reduced the production cost, it as the bonding material widely used in construction, ceramics, wood, textile,
