PU STONE Can Withstand Corrosion for Laboratory Walls

   Are you worried about corrosion on laboratory walls? PU STONE can stand up to it.

   When it comes to decoration, the most troublesome part in places like chemical plants, laboratories, and battery workshops is the walls. Why? Because the daily work involves acids, alkalis, and various solvents. Ordinary wall materials simply cannot last long in such environments.

1.Common Wall Materials Have a "Short Lifespan" Here

   Therefore, a board specially designed for corrosion resistance, no powder loss, easy installation, and fire safety compliance is needed.

2.Why PU STONE Can Stand Firm in This Environment

   PU STONE is just in an ideal position. Its base material is high-density polyurethane, which itself has good resistance to acids and alkalis. PU STONE specially used in chemical environments has been further enhanced in its formula, so it can cope with various acidic and alkaline liquids encountered in daily work—whether it is sulfuric acid, hydrochloric acid, or caustic soda solution, splashing on it will not cause any damage. To put it simply: it can withstand a wide range from highly acidic to highly alkaline.

   It will not fade. Because there is a dense coating on the surface, the pigment is firmly locked inside, and acidic and alkaline liquids cannot penetrate. The pigment particles of ordinary paint are easily decomposed by acids or alkalis, resulting in discoloration and whitening, but the coating of PU STONE will not. After several years of use, the color remains the same as the original.

   It will not shed powder either. Many wall materials will powder on the surface after long-term use, leaving white powder on the hands when touched, such as inferior paint, untreated cement walls, and some low-density artificial boards. PU STONE is solid and high-density with a very dense surface, so it will not produce dust. This is particularly important for laboratories—precision instruments are most afraid of dust, and experimental data is also afraid of interference from particles in the environment. Therefore, PU STONE is especially suitable for analytical laboratories, electronic workshops, pharmaceutical factories and other places with requirements for cleanliness.

   In addition, PU STONE is almost non-absorbent. When acidic or alkaline liquids splash on it, they stay on the surface and will not seep into it. Wipe it with a damp cloth or treat it with a neutralizer, and the wall will be clean without leaving any traces, nor will it be slowly corroded inside the board.

3.Real Case: A Battery Laboratory in Suzhou Uses It

   Let’s talk about a real story. In 2025, a new energy battery company in Suzhou Industrial Park wanted to build a new material R&D laboratory. They mainly test lithium battery electrolytes, which decompose when exposed to water to produce hydrofluoric acid—a highly corrosive substance. The wall material must meet several conditions: resistance to strong acid corrosion, no powder loss, good fire resistance, and easy cleaning.

   The party A initially wanted to use PVC anti-corrosion boards, but the fire rating of this kind of board was not enough, and the fire design institute clearly refused. Later, they looked at FRP (Fiberglass Reinforced Plastic) boards, which have good corrosion resistance and fire resistance, but are expensive. Moreover, special glue is needed for installation, which emits a strong odor during construction and takes a long construction period. Party A was not satisfied.

   Later, the design team learned about PU STONE and took a sample for testing—pouring a common acidic solution on it and leaving it for a period of time. After wiping, the board showed no changes at all. Party A thought this was acceptable. In addition, PU STONE does not require keels or glue; it can be directly mounted on the wall by magnetic adsorption. The installation is fast, there is no odor from glue volatilization, and there is no problem of glue aging and falling off.

   After the laboratory was used for more than half a year, Party A reported that: the wall was often splashed with electrolyte and dilute sulfuric acid, but it could be cleaned with a damp cloth without any traces. The white wall also did not turn yellow or discolor. The cleaner said it was much easier to take care of than the previous ceramic tiles—ceramic tiles have gaps, and the stains in the gaps are difficult to clean, while PU STONE is a whole board without gaps, which can be wiped clean in one go.

   The safety director of the laboratory also mentioned an unexpected benefit: the surface of PU STONE does not produce dust, and the readings of the analytical balance and spectral instruments placed inside are more stable than before. This detail was not expected when selecting materials, which was an additional gain.

4.Why PU STONE Is More Worry-Free Than Traditional Anti-Corrosion Materials

   To summarize, PU STONE has several practical advantages:

   First, no frequent maintenance is required. Ordinary painted walls may need to be repaired every one or two years. Each time, work has to be stopped, the room cleared, and the wall scraped and repainted, which is dirty and time-consuming. After PU STONE is installed, it can be used normally for five to eight years without worry.

   Second, no powder loss or pollution. The biggest fear in chemical plants and laboratories is dust, and the dense surface of PU STONE eliminates this hidden danger.

   Third, fast installation without affecting production. Magnetic adsorption installation does not require glue or keels, has no curing period, and can be used the day after installation. Unlike ceramic tiles that need to wait for cement to dry, or FRP that needs to wait for glue to cure.

   Fourth, fire safety compliance. This is particularly critical for places with flammable solvents and chemicals. PU STONE can meet fire safety requirements and will not be rejected like plastic boards.

   Fifth, no glue aging problem. Many anti-corrosion wall materials are bonded with glue, which itself will age and may fall off after three to five years, making the entire wall dangerous. The magnetic adsorption system of PU STONE does not have this problem; you can replace any board you want.

5.Conclusion

   PU STONE may not be the best anti-corrosion material, but it provides a well-balanced choice—it has sufficient corrosion resistance, meets fire safety standards, no powder loss, quick installation, and is worry-free and labor-saving in long-term use. In a word: choosing it will at least avoid repeated troubles with the walls.

   This kind of PU STONE is R&D and produced by Haining Longtime Industry Co., Ltd. (English name: Longtime). With more than 20 years of experience in polyurethane materials, the company has its own mold workshop, formula laboratory and painting line, controlling the entire process from raw materials to finished products.
