水相法氯化橡膠
水相法氯化橡膠（WCR）
Water-based Chlorinated Rubber (WCR)
水相法氯化橡膠是一種高硬度、粉末狀的熱塑性樹脂，它具有優(yōu)良的耐候性、附著性、化學(xué)穩(wěn)定性、耐鹽水性、防紫外線等性能。它可以穩(wěn)定的溶解在甲苯、二甲苯等有機(jī)溶劑和丙烯酸、醇酸等多種樹脂中，可形成無色或黃色的透明液體。當(dāng)這種溶液應(yīng)用到金屬、混凝土、紙等表面時，溶劑在室溫時可揮發(fā)留下一層透明、堅硬、有光澤的玻璃狀薄膜。這層薄膜可以防止水蒸氣和氧氣的透過，同時對各種化學(xué)物質(zhì)（如酸和堿）具有很高的穩(wěn)定性。它可以保護(hù)基體，防止腐蝕，可以用做裝飾的面漆。此外由于本產(chǎn)品具有很高的含氯量，所以具有優(yōu)良的防火性能。
水相法氯化橡膠可以廣泛應(yīng)用于油漆、涂料、印刷油墨和粘合劑中。是一種性能價格比十分優(yōu)異的功能樹脂，因此具有廣闊的應(yīng)用前景。
Water-based Chlorinated Rubber is a high hardness of the thermoplastic resin powder, it has excellent weather resistance, adhesion, chemical stability, salt water, UV and other properties. It can be stable dissolved in toluene, xylene and other organic solvents and acrylic, alkyd and other resins can form a colorless or yellow transparent liquid. When this solution is applied to metal, concrete, paper surface, the solvent can be volatile at room temperature, leaving a layer of transparent, hard, shiny glassy film. This layer of film can be prevented by water vapor and oxygen, while a variety of chemical substances (such as acid and alkali) with high stability. It can protect the substrate against corrosion, can be used as decorative finish. Furthermore, since this product has a high chlorine content, and therefore have excellent fire performance.
Water-based Chlorinated Rubber can be widely used in paints, coatings, printing inks and adhesives. Is a function of resin is very excellent cost performance, it has broad application prospects.
