The Glass Resins was
superior to the Ceramic product in abrasion resistance,
hardness, impact and MEK resistance. It was comparable to Si
coating in gloss, adhesion and chemical resistance.The
DLC Glass
Resins was superior to the Dow corning. OEM clearcoat in abrasion,
flexibility via mandrel bend and impact resistance. It was
comparable to the OEM clearcoat in gloss, adhesion,
hardness,chemical and MEK resistance.
Commentary from: During MEK double
rubs, the DLC Glass Resins exhibited a lot of lubricity where the
MEK seemed to have no impact on the clearcoat (even after 1,500
double rubs). In my experience with automotive clearcoats, there
is a certain amount of "drag" felt at the beginning or within 100
double rubs of the test. This "drag" was felt with the Si coating
and Dow corning. products. The
same phenomenon was noted when attempting to write on the clearcoat
with a permanent marker.
We were able to mark easily on the Glass Resins and Dow corning.
products with ink pen and permanent marker.
