封闭底漆(MS-CP)直接附着在基底上,其上附着有中涂、面涂,起承上启下的作用,良好的涂层系统在层与层涂膜之间没有层的界面,涂料施工要求每道工序之间可以进行有效的相互渗透,整个涂层成为一个整体,封闭底漆是附着在基材上的第一道膜,因而封闭底漆的质量要求很高,有良好的耐水、耐碱性、防水隔离盐碱渗出,有良好的附着力与层间附着力。
封闭底漆可以封闭基底,渗透到基材内部结构,堵塞基底中的毛细孔,降低基底中开放孔数量,增多封闭孔数,抑制涂料水分的渗透,使渗透变得均匀,使基底对上层涂料的吸收变得均匀。能防止水分,抗碱隔离作用,对基层的碱分能有效隔离,防止碱分的渗出破坏涂层。对疏松薄弱的基底进行补强作用,加固基底。
Closed primer is directly attached to the substrate, which is attached to the coating, surface coating, play a role,
not a good coating layer at the interface between layer and layer of coating film, coating construction requirements
between each process can effectivelypenetrate each other, the coating as a whole, is the first primer film is attached to thesubstrate,
the primer of high quality requirements, good water resistance, alkali resistance,waterproof isolation of saline exudation,
has good adhesion and adhesion between layers.
Closed primer can seal base, penetrate into the internal structure of the substrate, the substrate clogging pores,
reduce the number of open hole in the basement, increasednumber of closed pores, inhibit the infiltration of moisture
to penetrate the coating,becomes uniform, the basal layer on the coating becomes uniform absorption. To prevent moisture,
anti alkali isolation effect, on the base of alkali can effectively isolate, preventalkali exudation of damaged coating.
Reinforcing effect on loose basement, basementreinforcement.
