POLYAD SI -en

DESCRIPTION

It is a universal adhesion activator for bituminous conglomerates, extremely effective both on acid and basic stones, it avoids the stripping of the aggregates making up the conglomerate and extends its life.

APPLICATIONS

POLYAD SI can be used on any bituminous conglomerate; The addition of POLYAD SI has the effect of reducing the bitumen / aggregate contact angle. A smaller contact angle favors the adhesion of the bitumen to the surface of the aggregate, facilitates the wettability of the fine parts and above all facilitates the bitumen to enter the microscopic pores present on the surface of the aggregate. POLYAD SI also helps prevent the “stripping” of the bitumen from the surface of the stone aggregate.
The long molecules of the substances that form POLYAD SI, have a particular chemical structure which, added to the bitumen, rapidly migrate to the bitumen / aggregate interface

METHOD OF USE

POLYAD SI is added directly to the mixer of the production plant during the conglomerate production phase, using an automatic doser. Alternatively, it can be added directly to the bitumen storage tank when it is recharged.
