1. Product introduction:One-component polyurethane waterproof coating is a one-component reactive flexible waterproof coating that absorbs advanced foreign technology and uses imported raw materials and additives through polymer synthesis reaction technology. The material has good technical performance, is simple to use, and is convenient for customer construction. .
2. Main features (executive standard: GB/T19250-2013)
(1) Meet the testing standards;
(2) Can be directly constructed on base surfaces with a moisture content of ≤9% or on various dry materials;
(3) Single-component construction is simple and convenient;
(4) High solid content and low dosage per unit area;
(5) Excellent weather resistance, acid resistance and alkali resistance;
(6) It has unique water resistance and is the first choice material for underground waterproofing projects;
(7) Low temperature resistance can reach -40ºC, and high temperature resistance can reach 140ºC;
(8) Can be formulated into various color coatings.
3. Product application scope
One-component polyurethane waterproof coating can be applied directly on dry masonry, mortar, concrete, metal, various insulation layers, and various waterproof layers. It is suitable for new and old buildings and structures (such as industrial venues, large underground projects, subways, tunnels) , bridges, reservoirs, pools, etc.) can be used.
4. Construction technology
1 construction method
It can be applied by brush, roller or spray; directly apply it once (referred to as direct coating method); apply one cloth in 2-4 times: the pipe mouth and inner corners must use the additional cloth method.
2. Process
Clean the dust on the base layer; apply primer; after the primer is dry, apply two to four coats in sequence (the interval between each coat should not be less than 6 hours); when adding cloth. Cover the second coat while it is still wet, and wait until the covered coat is completely dry. Then apply two coats of paint on the top; when dealing with plastic pipe openings, first sand the pipe wall, and then apply waterproof coating; after the last painting is completed, it must wait at least 24 hours before handing over; do not move or stack on the coating before handing over object.
5. Things to note
Do not work in the open on rainy days;
It is not suitable for construction below 5 ºC;
It is not suitable to construct in a particularly humid environment;
In an environment with poor ventilation, the painting interval will be extended accordingly.
