Polymeric Car Body Sealant Made in Iran by Using Nanotechnology
‘Goharfam Industrial Manufacturing’ company has been able to produce the polymeric sealant with no solvent to seal the seams and distances left between the joints in the body and inside a car.
It can prevent the penetration of water, dust, and gas inside the car and withstand the friction and vibration during the vehicle movement.
The utilization of nanoparticles inside the polymeric matrix has resulted in increased viscosity of the sealer, improvement of the sagging resistance and enhancement of the shear strength of the sealant.
The sealant can be used in the body of vehicles for connecting the panels before welding and the interior parts of a car.
Earlier this year, an Iranian technological company had also managed to produce polymer sealants reinforced by using nanotechnology, which can minimize noise pollution inside cars.
Mohammad Nourmohammadi, the company’s manager for research and development, said Iran is the fourth country in the world that has attained the technology for manufacturing polymer baffles that are expandable.
The company produces sound insulation sealants for use in the automotive industry aimed to reduce noise pollution inside the car, he added.
The use of nanoparticles reduces noise pollution and decreases the amount of noise entering the car, he said, adding that the car’s body reinforcement materials and rubber insulators which have been manufactured by using nanotechnology are among the products of the company.
Producing sound and vibration insulators, polymer baffles (sealants) and related products, has made the company as one of the most important producers of bitumen-based magnetic insulators in Iran.
