Primer filler PX 07 – surface darkening prevention
Primer filler for antigraffiti coatings
PX 07 is a single-component, colourlessly drying dispersion of styrene-acrylic copolymer. It is used for priming absorptive, mineral substrates before application of anti-graffiti coating, which minimises or prevents the covered surface form darkening. It also enhances and evens out its absorptiveness. The product perfectly penetrates into the surface while improving its adhesive properties thanks to small size dispersion particles. PX 07 allows diffusion, has hydrophobic properties, protects the surface from penetration by hazardous substances and is UV and erosion resistant.
Product key qualities:
prevents colour deepening or changes,
strengthens the surface, paint layers, vulnerable natural stone substrates,
stabilises and evens out absorptiveness of all absorptive substrates,
improves paint adhesion to the surface and the coating durability,
improves surface coatings application rate,
ensures perfect adhesion to various mineral substrates,
We present an example of PX 07 primer works on an absorptive concrete surface with a different degree of absorbency. There is a connection: the higher the absorbance level, the higher the degree of darkness of the surface.
