Siloxane based decorative finish
RIALTO VELASIL
is designed to maintain a healthy, comfortable environment wherever
it is used. It achieves the optimal balance between water repellancy
and water-vapor permeability.
The microporous structure creates a superficial "membrane"
effect. This is a physical barrier to penetration of liquid water (rain)
but doesn't stop the water-vapor that can easily permeate the substrate
and the finish.
The structure obtained from a siloxane based decorative finish is a
film with a controlled and determined porosity. This porous structure
grants an excellent water-repellancy and water-vapor permeability.
The molecules of water-vapor are much smaller than the porosity of the
film, so they can flow easily through it, but not the molecules of the
liquid water that are much bigger and stopped by this physical barrier.
WATER REPELLANCY
The
substrate B has been treated with a siloxane primer.
Water cannot flow from area A to C.
WATER-VAPOR PERMEABILITY
Water,
if in a vapor form, can permeate the treated substrate B
and flow up to area A.
