1. Product Overview and General Use

RadonFree (RadonCoat) is a water-based eco-friendly coating product designed for use on concrete-based building structures.
The product consists of three components: base solution, main agent, and curing agent, which are mixed in a specified ratio and applied using brushes, rollers, or airless sprayers.

2. Main Functions and Applications

• Over 90% Radon Shielding Effect
  A single application effectively blocks more than 90% of the initial radon concentration, providing long-lasting, semi-permanent protection.

• Blocks Harmful Substances
  Effectively blocks not only radon but also harmful substances commonly associated with “sick building syndrome,” such as TVOCs and cement toxins.

• Antibacterial and Waterproof Performance
  Prevents mold, condensation damage, and corrosion throughout indoor areas.

3. Key Features

① Unparalleled Shielding Power

• Demonstrates over 90% shielding efficiency, significantly outperforming conventional radon reduction products (30–40%).

• Can be applied seamlessly to all indoor surfaces, including walls, ceilings, and floors.

② Environmentally Friendly and Safe

• Made with eco-friendly nano clay-based materials and water-based epoxy.

• Free from harmful adhesives, urethane, or other toxic substances, ensuring a safe indoor environment.

③ Semi-Permanent Effect with Minimal Application

• High crosslinking properties and superior durability enable semi-permanent performance with just one or two coatings.

④ Multi-Functional Protection

• In addition to radon, the coating blocks TVOCs, cement-related toxins, and prevents damage from mold, condensation, and corrosion.

⑤ Cost-Effective and Easy to Apply

• In-house production reduces manufacturing costs, resulting in lower consumer prices.

• The use of eco-friendly materials allows for safer, more convenient application by installers.
