Formaldehyde Removal Coating, Odor Eliminating Fluid “S-3T”

Formaldehyde Removal Coating, Odor Eliminating Fluid “S-3T”


The Solution for Indoor Air Pollution
and Sick Building Syndrome to Protect Your Life from Formaldehyde Gas

Odor Eliminating Fluid “S-3T” was developed as the solution for indoor air pollution. In the several substances of indoor air pollution, formaldehyde is the most serious issues and effect our daily life directly. Formaldehyde is known as a cancer causing, nevertheless it is found in various products such as plywood, particleboard, building materials, insulation and those products are necessity for our life. It means we have always risk of sick by formaldehyde by our living environment. Therefore, we need to deal with this formaldehyde gas emission problem. S-3T absorb and eliminate formaldehyde gas very easily. The efficacy lasts for a long-term, such as several years once it applies.

Major Features and Advantages

  1. High performance of eliminating formaldehyde gas by our own technology method

  2. Odor eliminating functions
    S-3T can absorb and eliminate several aldehyde gases, such as Acetaldehyde, Crotonaldehyde, etc. (Group 2B, possibly carcinogenic to humans).

  3. Long lasting formaldehyde removal effect
    The test specimens (S-3T and Blank) were placed in each flask that are filled with 100ppm of acetaldehyde and they stored under 50 deg C ×24hours. This is the test result to show the decrease in gas concentration for 24hours.

  4. Transparent coating film
  5. Safety materials (Confirmed laboratory test)
  6. Long durability
  7. Easy to handle (Spray, Brush, Roller coating)
  8. Other use
    S-3T eliminate not only formaldehyde gas but also burned smell such as fire disaster place and other including aldehyde gases as well.

    Think about your healthy life.

    【The risk of formaldehyde】

    What is formaldehyde?
    Formaldehyde is the chemical substance that has the acute toxicity, and it has a strong odor. IARC alerts the risk causing of Group 1, Carcinogenic to humans.

    How can you be exposed to formaldehyde?
    You can find formaldehyde in various products. Plywood, Particleboard, Building materials, Insulation, Furniture, Cigarette smoke etc. Therefore, we are always expose to small amounts of formaldehyde emission from those products.

    Health effect of formaldehyde (Sick building syndrome)
    ✓Headaches ✓Irritation of eye ✓Cough ✓Irritation of throat ✓Fatigue ✓Running nose ✓Rash skin ✓Nausea ✓Fever ✓Difficulty breathing ✓Tightness in the chest ✓Dizziness✓Allergy-like symptoms ✓Backache ✓Buzzing ✓Diarrhea ✓Constipation  

    If you have these symptoms after the renovation, purchasing some new furniture or moving house, it might be the sign of health damage by formaldehyde.

    S-3TTo protect your life from formaldehyde risk
    S-3T is the best solution to protect against formaldehyde exposure. We provide you clean indoor environment.

    How to use?

    Application 1: As the coating agent
    S-3T can be used for various locations to protect people from Formaldehyde risk. (Ex: House, Hotel, Condominium, Office building, Hospital, School, Nursing home, Furniture etc.)
    Recommend coating application method: Spray coating, Roller coating, Burh coating. You don’t need the professional techniques.

    Application 2: As the additive materials under the manufacturing process
    To add S-3T under the process of manufacture and it helps for manufacture to create the original product that can eliminate formaldehyde gas. This must be stand out characteristic, and it could be a great promotion to appeal the brand.

    Recommend user: Plywood manufacturer, Wallpaper manufacturer, Furniture manufacturer

    Competitive advantage

    1: Mechanism to remove aldehyde gas
    Generally, formaldehyde eliminator is manufactured based on neutralized effect. However, we developed the new technology of absorbing and eliminating that is based on SiO2 by sol-gel method.

                                                             Fig. 4 The image of amine modified silica particles

    S-3T is made from silica that has the chemical treatment by Amino group. The Amino group reacts against Aldehyde group then it leads to absorb and eliminate formaldehyde gas.

    2: Long lasting efficacy
    S-3T continues to eliminate formaldehyde gas for 4~5 years as compared with other product last only 1 or 2 years. Therefore, no need maintenance frequently and it leads to save running cost.

    3: Long durability
    No deterioration on the coated surface and keep clear appearance.


      1. Maximum eliminating performance: 600mg/m2(600,000μg/m2)
      2. Long lasting efficacy: 4~5 years
      3. Performance of formaldehyde reduction: 99 %

                                Test Certification

      Technical maturity / Past record of introduction

      S-3T was developed in 2011. Since then, we have been providing many counties to protect against formaldehyde risk.
      As the most recent data, we exported S-3T as the materials for 800,000㎡ area (as of annual 2021).
      Our main market is Southeast Asia and East Asia though, we would like to expand this great product S-3T to all over the world because formaldehyde problem is the social issue in the world.
