A hardener for substrate reinforcing that doesn't create dust: it's called R-evolution HD and it bears the Technokolla trademark. It's the first and only product that really cuts down on dust emissions, thus safeguarding the health of the operators, who can work in a more wholesome environment. The fine dusts that remain in the air in indoor construction sites are no longer a problem for the eyes, nose and skin thanks to High Definition technology's clean "revolution". There's less dispersion since the special chemical composition allows a smaller quantity of product to be used during the "dusting" operation, with evident economic and environmental benefits.
