MASTIC TECHNONICOL No.57
Ready to use solvent-based reflective polymer-bitumen mastic used for installation and recovery of protective layer on roofs
Ready to use reflective bitumen mastic TECHNONICOL No.57 presents a mix of high-quality bitumen, special polymers, aluminum pigment, additives and organic solvents. Coating layer formed by the mastic effectively protects the bitumen roofing against UV rays and heat; it also protects the metal roof from corrosion.
Mastic TECHNONICOL No.57 is used for:
- installation of the protective layer on new mastic roofs;
- recovery of the protective layer on old roofs;
- corrosion protection of roof coverings.
Before application, the mastic has to be carefully mixed for homogeneous distribution of aluminum pigment. The mastic is applied to a surface by brush, roller or airless spraying device. Application of 2 mastic layers is recommended for reliable protection.
The product should be stored in a dry place protected from direct sunlight at temperatures from -20°C to +30°C. Shelf life – 18 months.
