Laminate coatings are combinations of reaction resins with fiber materials (glass-fiber mats, fabrics). Šey are characterized by highly mechanical durability and even
layer thicknesses. Šeir high durability qualifies them, for example, for use in bridging
cracks in concrete parts that are to be coated.
Glass-fiber mats are of great importance for strengthening purposes, because the evenly spread fibers enable the mechanical strength characteristics to be increased in all
directions. Še mats often contain E-glass fibers and in special cases also ECR- or
C-glass fibers. Še mass per unit area (weights) are usually 300 or 450 g/m2
.
Še applied glass mats are normally covered with a surface veil. In laminate coatings,
they are used to build up the chemical protection layer. Še surface veil materials
mainly determine the coating surface and directly affect its chemical properties. Še
resin-rich surface veil layer that covers the laminate layer should exhibit a sealed and
even surface to prevent media penetration via glass fibers that have not been saturated in the resin. By preference, surface veils made of durable C-glass are used. Surface veils made from synthetic or carbon fibers offer resistance to special media such
as hydrofluoric acid. Carbon-fiber surface veils, also known as hybrid surface veils, additionally impart an electrostatically conducting quality to the cover layer. Še mass
per unit area (weight) of these veils 20 to 50 g/m². REMA TIP TOP uses synthetic
resins based on furane, phenol, vinylester and epoxy for its laminate coatings, which
are distributed under the brand names TIP TOP LINING, ESKANOL and Asplit.
