TEKNOFINISH HAILRESIST 4800-22

Topcoat for spray application

»

TEKNOFINISH HAILRESIST 4800-22 is a water-borne, industrial topcoat for planed wood designated for exterior windows, doors, and cladding.

Unique film technology absorbs the energy when struck by hail, preventing the coating film from cracking. With excellent adhesion and surface levelling, TEKNOFINISH HAILRESIST 4800-22 delivers high transparency through the coating film and is tintable to a wide range of shades. When using softwood, it is a requirement that the growth ring angle in relation to the primary exposed surface of the wood is kept between 5° and 45°. CERTIFICATES, APPROVALS: - Is blocking resistant according to EN 927-10:2019. - Showed no cracks in the extended impact test according to EN 927-13:2019 with energies corresponding to the hail resistance class 3 of the classification system “Hagelregister”. - When tested by the hail gun test in accordance with hail resistance class 3 of the classification system ‘Hagelregister’, the product showed no cracks on impact sites.
