Innovative Binder Technology for High-Solids Industrial Coatings
impact test.
This property of silicone hybrid resins
leads to good deformability and adhesion
of the coating on different substrates.
Compatibility
The compatibility of silicone hybrid resins in current binders is also very good
and well balanced. Compatibility with
various resins is shown in Table 7.
Pigmentability
It should be noted that silicone hybrid
resins have very good pigment wetting
properties both in tinting with pigment
pastes and in direct grinding with mixed
pigmentation. This property promotes
the corrosion resistance of the formulations. However, wetting and dispersing additives are necessary to formulate
high-gloss paints with the lowest haze.
In artificial weathering to ISO 4892-2
both silicone hybrid resins show color
change ΔE < 1.0 after 6000 hours which
permits good long-term color stability
of the paint.
