Duraproof AC 300
Premium, elastic, acrylic waterproofing coating
Description Density 1.15 ± 0.05 kg/l
(EN ISO 2811-1)
Duraproof AC 300 is a premium, elastic,
waterproofing coating based on 100% acrylic UV- Waterproofing 7 atm
cross-linking resins. Offers absolute water (DIN 1048-5)
impermeability, protecting walls against rain Water vapour permeability Sd = 0.29 ± 0.05 m
damage. Features high elasticity and crack- bridging (EN ISO 7783:2011 V2
ability, making it ideal for surfaces prone to hairline medium, 0.14< Sd < 1.4 m)
cracks up to 1 mm. Maintains its elastic properties
over a temperature range of -20°C up to +80°C. CO2 Permeability Sd = 177 ± 10 m
Being vapor-permeable, it allows building (EN 1062-6 requirement: Sd
> 50 m)
breathability, while preventing ingress of CO2 and
other aggressive agents. Provides excellent opacity Adhesion Strength ≥ 2.2 N/mm2
and surface coverage, as well as strong adhesion to (EN 1542, requirement for
the substrate and outstanding resistance to flexible systems with no
weathering and UV radiation. Abrasion resistant to traffic: > 0.8 N/mm2)
light foot traffic. Solar Reflective (White) 89%
The white is certified as Heat Reflective Cool Paint. (ASTM E903-96)
(ASTM G159-98)
Certified according to EN 1504-2 and classified as a
Infrared emittance coefficient ≥ 0.86
coating for surface protection of concrete. (ASTM C1371-04a)
