罩面漆，是一种液体透明胶状物，施工时需兑水来稀释，这种产品可以使用在壁纸漆、建筑外墙、木制品等表面，起到防尘、耐污、耐擦洗的效果，因此，罩面漆也被叫作防尘漆。罩面漆使用跟不使用有什么区别？

The finish paint is a liquid transparent gel, which needs to be diluted with water during construction. This product can be used on the surface of wallpaper paint, building exterior wall, wood products, etc., to play the effect of dust prevention, dirt resistance and scrub resistance. Therefore, the finish paint is also called dust-proof paint. What is the difference between the use of finish paint and not use?

1、从颜色持久性上来讲

1. In terms of color durability

罩面漆常用于地坪和外墙上，从颜色持久性来上讲，罩面漆的使用从完成施工开始是一时半会看不出什么特别不一样，但随着时间的长久，从颜色上来看，就会越来越明显。

Finish paint is often used on floors and exterior walls. From the perspective of color durability, the use of finish paint will not be particularly different for a while and a half from the completion of construction, but it will become more and more obvious from the perspective of color over time.

2、从使用寿命上来讲

2. In terms of service life

以外墙为例，不仅可以提高涂层耐紫外线照射性能，还便于墙面日后的清洗。所谓底漆固底层，用于提高面漆的附着力、加固腻子层、增加面漆的丰满度、平滑度、提供抗碱和防腐等功能，是从内保护墙面，而罩面漆是为了增强涂层的防水性、耐沾污性和耐候性等功能，是从外保护墙面，两者结合，一内一外保障墙面的使用寿命。中间还有一个面漆，一底两面，再加个罩面，三者结合是佳搭配了，在使用寿命上就更加一层楼了。

Taking the exterior wall as an example, it can not only improve the ultraviolet radiation resistance of the coating, but also facilitate the future cleaning of the wall. The so-called primer is used to improve the adhesion of the finish coat, strengthen the putty layer, increase the fullness and smoothness of the finish coat, and provide alkali resistance and corrosion resistance. It is used to protect the wall from the inside, while the finishing coat is used to enhance the waterproof, stain resistance and weather resistance of the coating, and it is used to protect the wall from the outside. The combination of the two is used to ensure the service life of the wall from the inside and the outside. There is also a topcoat in the middle, a bottom and two sides, and a cover. The combination of the three is a good match, and the service life is even higher.

3、从抗污自洁性上来讲

3. From the perspective of anti-fouling and self-cleaning

罩面漆表面优疏水性，流水经过时，涂料分子与水分子相互作用，在其表面形成一层水膜，使得附着的污垢在浮力的作用下和涂层表面分离，又在水滴自身重力的影响下，随着水膜的流动被带离，形成“自动清洁表面”的效果。

The surface of the finish paint has excellent hydrophobicity. When flowing water passes by, the coating molecules interact with water molecules to form a water film on its surface, which makes the attached dirt separate from the coating surface under the action of buoyancy, and under the influence of the gravity of the water droplets, it is carried away with the flow of the water film, forming the effect of "automatically cleaning the surface".

这样的涂料应用于室外时，雨水便可以自动清理表面的部分污垢，应用到室内时，既可以用潮湿的抹布去污，也可以用流水直接冲洗，容易导致涂层不耐水、泛白及易污，也可缩减涂层的寿命。

When such a coating is applied outdoors, the rainwater can automatically clean some dirt on the surface. When applied indoors, it can be decontaminated with wet rags or washed directly with running water, which is easy to cause the coating to be water resistant, white and dirty, and can also reduce the life of the coating.

3、从抗碱和抗紫外线上来讲

3. In terms of alkali resistance and ultraviolet resistance

罩面漆涂刷后不会破坏原墙面装饰效果，不会出现变黄、沾尘等现象。耐热、耐紫外线、耐酸碱，涂膜具有较好墙面保护。

The finishing coat will not damage the original wall decoration effect, and will not turn yellow and dust. Heat resistance, UV resistance, acid and alkali resistance, the coating film has good wall protection.

特别是靠近海边的建筑，罩面漆就是一个很好的案例，在自然环境下，还经海风不断侵袭，墙面的风化侵袭程度比一般建筑的伤害要大得多，如果没有罩面漆，容易导致外墙涂层在海风的侵袭下慢慢变得不耐水、泛白及易污，从而缩短外墙涂层的寿命。

Especially for buildings close to the sea, the finish paint is a good case. In the natural environment, the weathering of the wall is much more harmful than that of ordinary buildings. If there is no finish paint, it is easy to cause the outer wall coating to become water resistant, white and dirty under the attack of the sea wind, thus shortening the life of the outer wall coating.

而罩面漆作为外墙涂料的封面层，可以从外保护涂料墙面，延长外墙涂料的使用寿命。罩面漆有良好的抗碱和抗紫外线的作用，像外墙涂料处于室外，特别是靠海边的建筑，天气多变，罩面漆可以大大的保护外墙涂层的美观和持久性，节省二次维护的成本。

As the cover layer of the exterior wall coating, the finishing coat can protect the painted wall from the outside and extend the service life of the exterior wall coating. The finishing coat has good alkali resistance and ultraviolet resistance. For example, the exterior wall coating is outdoor, especially for buildings near the sea, and the weather is changeable. The finishing coat can greatly protect the beauty and durability of the exterior wall coating and save the cost of secondary maintenance.

总之良好的产品性能使得罩面漆在广大消费者的心里还是占有一定的分量，这也是罩面漆近年来的热度上升的原因。您有需求就来联系我们咨询选购吧！
