Company in Iran Uses Inorganic Nanoparticles to Make Epoxy Stone Adhesive

‘FERMA High-tech’ engineering Co. Ltd has produced the epoxy stone adhesive with a high degree of flexibility and transparency which enables filling the gaps due to its excellent adhesion.

The shear strength of this product has been promoted through the dispersion of inorganic nanoparticles in the polymeric matrix in low concentrations.

The incorporation of certain inorganic nanoparticles into the basic epoxy has led to higher compressive strength, improved resistance to sagging, better elastic modulus, shear strength, and hardness

The special epoxy stone bonding adhesive can be applied for outdoor applications (facades) and as an alternative mortar for building mortars, stick stones, concretes, and bricks.

In a relevant development in April, a faculty member of Islamic Azad University’s Tabriz branch in Northwestern Iran succeeded in designing and manufacturing fibrous nano polymer bricks for construction of buildings which enjoy waterproof properties.

“The nano-gypsum fiber waterproof panels have been developed based on the state-of-the-art technologies in the world and they enjoy compressive strength of at least 3 mega pascals, with a low density of about 400-550 kg/m3,” said Yousef Zandi, the researcher of the project.

Noting that the polymer bricks enjoy many good features, he said that they do not need plaster and soil, absorb adequate water when used in construction operations and show excellent adhesion with cement and high thermal insulation.

Zandi added that the gypsum nanopolymers are as light as wood and they have special properties like very low density (400 to 550 kg per cubic meter), heat insulation, sound insulation, and greater resistance to freezing and erosion, saying that the use of these gypsum nanopolymers in construction reduces over 30% in construction costs and more than 70% in cooling and heating costs.
