Today, let me give you a detailed explanation of the DPS product.
DPS is a product called Deep Penetrating Sealer from Evercream Corporation in the United States. DPS is the acronym for this product, which entered China in the 1990s and was named Yongning Liquid with a registered trademark. Others calling it Yongning Liquid is actually an infringement. With too many people calling it that now, it has become a generic product name by default

Let's talk about the characteristics of DPS again. One important point is that it is hydrophilic, which has been clearly defined in the new standard JC/T1018-2020, namely water absorption and waterproofing, which is commonly known as water treatment. That's how water treatment comes about. It's not like some companies say that spraying materials like water without water is called water treatment. This has nothing to do with using water to control water. Permanent setting fluid DPS is a crystal formed by reacting with alkali in concrete in the presence of water after infiltration into concrete, to seal the capillary pores of concrete and achieve waterproof effect. It is inorganic and basically does not age. The longer the time, the better the concrete will seal, the better the waterproof effect, and the better the effect. It can have the same lifespan as concrete.
What are inorganic materials and organic materials? For example, stone is an inorganic material and plastic is an organic material. Stone has much better durability and weather resistance than plastic, and it basically does not age. This is why inorganic materials are good.
Next, let's talk about hydrophilicity. This characteristic is clearly defined in the new standard JC/T1018-2020 to distinguish silicone waterproofing agents. Hydrophilicity refers to the ability of the surface to absorb water after spraying, making it look as if it has not been waterproofed. This is also a reason why many people cannot accept it. Spraying it feels like there is no effect at all, so it is difficult for people to accept it, which makes this material very difficult to promote. It's not as easy to accept as organic silicon. The characteristic of organic silicon is that it rolls off like water droplets when sprayed on the surface. The surface looks good, but it doesn't have internal sealing function or impermeability. It's basically useless in humid environments.

A simple way to identify the permanent set liquid dps and organic silicon can be to mix cement and the same amount of materials. The permanent set liquid will generally react with the cement in one minute to gel, and the organic silicon will not react with the cement gel.
The current market situation of permanent solidification liquid DPS is that in recent years, this material has suddenly become ubiquitous. When searching online, various qualities vary greatly, resulting in a good material being made into a mess. Some people may say that our materials meet the standards without any problems, but are they effective? The current JC/T1018-2006 inspection standard is too simple and lacks technical content. For those with some technical content, DBJ01-54-2001 can be used to test the material's impermeability if one of the anti permeability pressure ratios is greater than 200%. However, if the material is only measured according to the inspection standard, it will be far from satisfactory. The quality of materials also depends on their effectiveness in practical applications.
