HDK H18 silica

HDK H18 silica has been developed specifically for use in polar systems, such as
epoxy resins and polyurethanes. It is
characterized by a high specific surface
area, and has a specific coating which
renders it highly hydrophobic. This makes
it particularly adept at controlling the
rheology of polar systems. HDK H18 silica also imparts remarkable longterm storage stability and excellent efficiency. This means not only that the proportion of pyrogenic silica in bonding
pastes can be reduced, but also that the
cured resin has less tendency to embrittle.
The blend of the two adhesive components, too, exhibits superior rheological
properties at very low HDK® H18 content.
