PrimeCoat 9026 是一种水溶性的无铬钝化液,以硅烷为主体给金属表面提供极好的防锈保护,同时提供一定的外延性能。在电镀锌、热镀锌和热镀锌铝合金表面均有很好的应用表现,酸度中等,不会腐蚀设备。该产品不含有毒的金属离子比如铬、钒等。

PrimeCoat 9026在金属表面形成透明的化学皮膜,为基材提供极好的防锈保护,湿热后的盐雾依然有很好的表现(模拟运输)同时具备较好的焊接性能和自润滑性能能满足各种裁剪和形变的需求,以及极好的后涂装性能等多达15种以上的外延性能。应用在不同厚膜的状态下可以具备耐指纹处理膜和彩涂预处理的特性。

应用在锌和锌合金表面:

在室温环境下辊涂不需要水洗,尽量避免入口温度 > 50°C,无需加热。

钢板表面烘干温度 >70-120°C 时间2-5 秒,应用浓度100%,无需稀释

推荐用XRF和我公司提供的标准曲线来检测板面的膜厚.



PrimeCoat 9026 is a water soluble chromium-free passivating solution with the main content of silicane, which gives an excellent antirust protection and certain extension performance to the metal surface. It shows good application performance on the surface of electrogalvanizing coating, hot galvanizing coating and hot galvanizing aluminum alloy coating. Its moderate acidity brings no corrosion to the equipment. The product contains no toxic metal ions such as chromium, vanadium, etc. 

PrimeCoat 9026 forms a transparent chemical film on the metal surface, which gives super antirust protection to the base material. After damp heat test, it still shows excellent performance (simulative transportation) in the salty fog test. Besides good welding performance and self-lubrication performance which can meet various demands of cutting and deformation, it possesses more than 15 kinds of extension performances such as excellent afterwards-coating performances and so on. It can show performances of fingerprint-proof film and color-coating pretreatment at different film thickness. 

Product application

Be used on the surface of Zinc and zinc alloy.
 
Rinsing is no need for roller coating at room temperature. Entrance temperature > 50℃ should be avoid. Heating is no need.
 
Drying temperature of steel plate surface >70-120℃, 2-5 seconds, application concentration of 100%, no dilution.
 
XRF and the standard curve provided by our company are suggested to be used to examine the film thickness of plate surface.
