产品说明书(Product Description)
HEC300P是一种非离子的水溶性聚合物，可用于水性涂料中的保水剂和流变学改性剂。HEC300P是羟乙基纤维素的高粘度级。它是在一个等级，具有生物稳定性的溶液，以防止酶攻击。
HEC300P is a nonionic ,water-soluble polymer from wood pulps or cotton linters that can be used of water retention aid and rheology modifier in water-based paints. HEC300P is a high viscosity grade of hydroxy ethyl cellulose. It is available in a grade that has bio-stability in solution against enzymatic attacks.
应用(Application)
HEC300P广泛用于水性涂料。它具有良好的假塑料流动性，与有色颜料、乳胶聚合物、表面活性剂、乳化剂、消泡剂和防腐剂具有广泛的相容性。为了避免因快于最佳溶解速度而导致结块，HEC300P经过适当处理，以实现应用的最佳水合时间。
HEC300P is widely used for water-based paints. It provides good pseudoplastic flow and wide compatibility with colored pigments, emulsion polymers, surfactants, emulsifiers, defoamers, and preservatives. In order to avoid lump formations caused by a quicker than optimal dissolution rate, HEC300P is properly treated to achieve optimum hydration time for the application.

存储和包装(Storage & Packaging)
HEC300P为25公斤净重多层纸袋，内衬聚乙烯。HEC300P由于其吸湿性，应在干燥清洁的条件下保存在原包装中。如果没有，HEC300P可以吸收空气相对湿度的水分。HEC300P不是一种易腐的产品。
如果保存在密封的容器中，在其原始包装和干燥的地方，在室温下，HEC300P可以保持其原有的性能。
HEC300P is packed 25kgnet multi-layer paper bag with polyethylene inner liner. HEC300P should be stored under dry and clean conditions in its original packaging due to its hygroscopic property. If not, HEC300 can absorb moisture relative to the humidity in the air.HEC300P is not a perishable product.
If it stored in closed containers, in its original packaging and in a dry place at room temperature,HEC300P can maintain its original properties.
