The company’s product is an antibacterial moisture-proofing powder containing nanoparticles and it has shown effective antibacterial capabilities by utilizing nanotechnology.

The product is used for sealing various surfaces like swimming pools, water tanks, toilets, gable roofs, and retaining walls. High adhesion to various surfaces, easy use, and high speed of implementation are among its advantages which can cover the various needs of the construction industry.

This nano-insulation powder is supplied ready-to-use to the consumer and can be applied by simply adding water and using a brush or roller. After drying, it creates a resistant, durable and moisture-proof layer. High flexibility, easy application on monolith or metal columns, resistance to water pressure and abrasion, and the possibility of vapor passage for the underlying surface are some of the outstanding features of this product.

In addition to its construction capabilities, this powder, using antibacterial nanoparticles, has shown significant performance in combating pathogenic bacteria.

In a relevant in 2022, an Iranian inventor had also managed to produce an insulating material that is able to replace traditional bitumen in buildings.

The new insulation can be used instead of fabrics soaked in bitumen that is used traditionally in the construction industry.

Roham Faraj Mohammadi, the inventor, told ANA that with 11 years of professional experience, his activities are focused on insulating buildings and facilities, notably in petrochemical complexes.

“After working for a while, I felt that there is a need for a special material that can be used in different places and has high heat resistance.”

Materials that can provide thermal and moisture insulation and acid resistance for use in industry, petrochemicals, and distillation towers are imported at a high cost, he pointed out.

“After several years of research, I found an insulator and applied for a patent. In terms of formulation, there was nothing like this in Iran.”

These polymers are not hydrophilic at all and cannot be dissolved or mixed with water. But I created conditions for it to be combined with water-based resins, he explained.
