LAPO Co., Ltd

We provide catalyst-type deodorizing coating that works in dark places at room temperature for an extended period of time

Our company develops and provides customized catalyst-type deodorizing coating for a wide variety of customer needs. We make an optimal catalyst coating for individual customers as a trial prototype, and the products are adopted after the performance is confirmed. The main feature of our catalyst coating is that it uses a catalyst that remains effective at room temperature even in dark places. It tends to oxidize offensive molecules just a bit better if light is present. It can be used in a wide range of fields including existing air washers and exhaust air ducts in large buildings, and clothing, bedding and kitchens in everyday life.

We provide customized catalyst-type deodorizing coatings for individual use cases
The aim of our deodorizing coating
Our company develops catalyst-type deodorizing coatings that use metal nanoparticles such as platinum, silver, copper, and nickel, and nanoparticles of molybdenum oxide, niobium-doped titanium oxide, and new tungsten compound. The main feature of our company is that we develop and manufacture catalyst-type deodorizing coatings that can decompose formaldehyde, ammonia, tri-methylamine, and other substances even in dark places at room temperature. Public institutions such as KAKEN and Japan Food Research Laboratories have confirmed that products treated with these coatings have certain deodorizing properties for formaldehyde and ammonia in dark places at room temperature. They can pass SEK standards for photocatalyst-type articles even when tested in the dark. Our deodorizing coatings are also colorless and transparent as they use extremely small oxide nanoparticles. 

Conventional deodorizing agents and coatings are divided into two types. One is the binding type, which creates a functional group with organic molecules to have it react to offensive molecules. The other is the absorbing type, such as activated charcoal and zeolite. Both have a crucial problem in that their deodorizing performance is not long-lasting. They have either a reaction limit or an absorption limit, and eventually saturate, losing their deodorizing effect.

Our catalyst-type deodorization products do not have such problems. Most catalyst-type deodorization products decompose offensive molecules through oxidative deodorization by using light energy. We can adopt that mechanism, but we would rather use our original catalyst because it can generate oxygen radicals with heat energy in the room temperature range. This enables oxidative deodorization for offensive molecules. The catalyst has sufficient deodorizing performance in dark places. We have improved performance even further, and we were able to develop a catalyst coating that deodorizes perfume in the dark at room temperature. We plan to launch it next year or later.

The basic concept of our deodorizing business is to change the formula of catalyst-type deodorizing agents based on the specifications required by the customer. This includes the type of odor that needs to be decomposed, and the components of that odor. That is why we have no general-purpose products in our offerings. We offer very different deodorization formulas for clothing and industrial waste buildings. We have meetings with customers, and sometimes ask them to provide samples that have to be dealt with. The final catalyst coating is customized for individual companies before being delivered to the customer. Our products have already been adopted by well-known apparel manufacturers, and they are used in large buildings. We also add antibacterial and anti-mold functions, as they are requested by some customers.
Notable differences from the competition
Our products are fundamentally different from the competition. They retain their deodorizing effects against ammonia, tri-methylamine, formalin (formaldehyde), and cigarette odors continuously for a long time, even in dark places at room temperature. Reaction and absorption types have their own limits. The reaction type loses its deodorant effect once its reacting function group is lost, and the absorption type eventually saturates. Either way, their deodorizing performance is not long-lasting. The catalyst type continues to deodorize for a long period of time as long as its active surface is not damaged. Our customers have obtained results confirming that the duration was incomparably longer than other products.
