The product is a kind of fire retardant coating for steel structure, that is based on water-borne resin emulsion. It is used in flameproof protection of the surface of the indoor steel structure. It has the special properties like environmental, long fire resistance, high bonding strength and easy to construct. It has been sampled by China Certification Center For Fire Products Ministry of Public Security, and taken the Type Approval Survey by CNCF(China National Center for Quality Supervision and Test of Fixed-fighting Systems and Fire-resisting Building Components). All the performance indicators reache or exceed the GB14907-2002.
2、PRODUCT FEATURES 粘接强度高、耐火极限长、装饰效果好、绿色环保无污染、施工方便。
1）High bonding strength; 2）Long fire resistance; 3）Good decorative effect; 4） environmental; 5）Easy to construct. 三、应用领域
It is widely applicable to the fire protection for buildings or other structures, the indoor bearing steelwork of the large steelwork workshorp and the steel grid structure. It also can be used for the steel-structure building of petroleum industry, chemical industry, metallurgical industry, electric utility and Coal industry. 四、施工工艺
1） Clean the dust and the attachments on the surface of steel structure clearly. Must derust the parts which get rusty. Anticorrosive paint twice. 2、待底漆干透,清除防锈漆表面尘土、污物后方可涂刷NB-1室内薄型钢结构防火涂料。
2） The NB-1 could be used when the anticorrosive paint is dry enough, and there is no dust on the surface. 3、NB-1室内薄型钢结构防火涂料一般采用刷涂、辊涂或喷涂工艺进行施工。涂料在使用前，须充分搅拌均匀。
3） Fully stir well before used. The coating method like Spraying, roller coating, brush could be used. 4、为保证附着力，施工时第一遍涂层厚度须≤0.3mm，待前遍涂层干透后再涂下一道，以后每遍涂层厚度≤0.5mm，直至总厚度达到设计要求。
4） The thickness of the coating should control in 0.3mm in the first time construct to ensure the intercoat adhesion. Then to the next coating ,each thickness should control in 0.4mm, until the total thickness is up to the standard. 5、该产品为水性涂料，施工温度10℃以上为宜，湿度不大于85%，遇有雨、雪、雾、大风天气或钢材表面有结露时，不宜施工。
5） The temperature when the construction is going on should be above 10℃, for this product is water-borne, and the humidity should be lower than 85%. It couldn’t going on when there’s raining, snowing, misting, winding or dewing on the surface. 6、未用完的涂料应密封保存，已备再用。
6） The rest of the coating should be sealed so that next time still be useful.
