三、包装及贮运

本品在通风良好处低温(0℃-30℃)密闭贮存,避光。有效贮存期6个月,超期复验,若符合标准,仍可使用;常规包装200Kg/桶或20Kg/桶,可根据用户需求协商指定包装。SH-1297按非危险品贮运,其它型号按易燃品贮运。

四、施工参考

1、本品可采用刷涂、喷涂、浸涂等方法施工。涂层以不流卦、不漏涂为准。

2、涂装前,须先将待涂物件表面的水份和油污除净。

3、第一道涂膜表干后,才可涂第二道。

4、本产品为单组份包装,固化时,依靠接触空气中水份固化。空气湿度含量越高,涂料固化越快;温度越高,涂料固化也越快。因此,一次未用完应及时将容器密封以备下次再用。

5、施工时应严禁明火,且避免穿戴易产生静电的工作服。

 

Silicone Conformal Coating

 Properties&Uses

This product is a light yellow transparent liquid, is a silicone conformal coating, with good adhesion, moderate strength, good resistance to hot and cold alternation, high resistance to vulcanization, moisture resistance, weather aging, low odor and environmental protection. The product viscosity is medium, can be cured by both room temperature and heat curing. After curing, it has good adhesion with metal, PCB plate and other substrates, and can be used in electronic and electrical appliances, home appliance industry, digital electronics, led, automobile industry, aerospace, navigation, medical and other industries. Providing a full range of protection for these industries, such as electronic devices, circuit boards, communication devices and other precision components, giving them moisture-proof, salt spray-proof, mold-proof, dust-proof, shock-proof, anti-corrosion, anti-leakage, anti-aging, insulation, life extension and other functions. This product can be added with ultraviolet fluorescent agent, which is convenient for leakage detection in later construction.

III Packaging, storage and transportation

It is recommended to store the product in a well-ventilated and low temperature(0 - 30 ) away from sunlight. The effective storage period of the product is 6 months. Overdue the storage, if the product meet the standard, it can still be used. General packaging 200kg / iron drum or 20kg / iron drum, the packaging can be specified according to the needs of users. SH-1297 is storied and transported as non-dangerous goods, other types as dangerous goods.

 

IV Application Methods

1. This product can be applied by brushing, spraying, dipping and other methods. The coating shall be free from sagging and leakage.

2. Before painting, the water and oil on the surface of the object to be painted must be removed.

3. The second coating can be applied only after the surface of the first coating is dry.

4. This product is a single component packaging, curing depends on contact with water in the air. The higher the air humidity content is, the faster the coating solidifies; the higher the temperature is, the faster the coating solidifies. Therefore, if it is not used up at one time, the end of the barrel should be covered in time for reuse next time.

5. Open fire shall be strictly prohibited during construction, and work clothes easy to produce static electricity shall be avoided.
