Intumescent varnish for timber AITHON PV33 (20 kg)
AITHON PV33 fireproof paint for wooden structures
AITHON PV33 is a transparent, water-based, heat-expanding fireproof paint for wooden structures and is classified according to ENV 13381-7 (R15, R30, R45 and R60) and EN 13501-1 (B-s1-d0).
At room temperature, the paint enhances the natural appearance of the wood, but in the event of a fire, it swells, forming a thick microcellular foam layer that acts as an insulating shield between the flame and the wood.
· Classified R15, R30, R45, R60 according to ENV 13381-7 for wooden beams, columns, floors, and load-bearing walls;
· Classified B-s1-d0 according to EN 13501-1 for all types of wood with a density above 390 Kg/m2 and a thickness of at least 10mm;
· “A” class certificate regarding VOC emissions;
