Technical Datasheet One-component, fiber-reinforced, thixotropic, polyurethane, liquid waterproofing membrane for roof details and connections. ISOFLEX PU 500 DTL is based on elastomeric, hydrophobic polyurethane resins of excellent mechanical, chemical, thermal and weather resistance. The product has additionally the following properties: • Forms a continuous, elastic, waterproof, vapor-permeable layer, without seams or joints. • Features excellent adhesion to various substrates, such as concrete, screeds, wood, metal, bituminous membranes and most waterproofing membranes. • Applicability even to irregular substrates. 2. Properties of the cured membrane Elongation at break: > 100 % (EN-ISO 527) Hardness according to SHORE A: 78 ± 2 Water vapor permeability: Sd = 0.82 m Fields of application Bond strength to concrete: > 2 N/mm2 (EN 1542, requirement for flexible systems with no traffic: 0.8 N/mm2) Pass (no blistering, cracking or flaking) Euroclass F ISOFLEX-PU 500 DTL is suitable for waterproofing roof details such as: • Wall-floor junctions • Pipes • Gutters • Skylight domes • Chimneys • Rooftop ventilation and air-conditioning units. • Photovoltaic systems • Solar systems prepolymer Color: white Artificial weathering: (EN 1062-11, after 2000 h) Reaction to fire: (EN 13501-1) Service temperature: 1. Substrate preparation The substrate must be dry (moisture content < 4%) and free of grease, loose particles, dust, etc. 1.1 Concrete surfaces Any existing cavities in concrete should be repaired in advance. Severe cracks on the substrate must be locally primed and after 2-3 hours (depending on the weather conditions) must be sealed with the polyurethane sealants FLEX-PU 30 S or FLEX-PU 50 S.

Concrete and other porous surfaces with moisture content < 4%, should be treated with the primer PRIMER-PU 100, at a consumption of approx. 200 g/m2. Surfaces with moisture content > 4% should be primed with the special two-component polyurethane primer PRIMER-PU 140, at a consumption of 100-200 g/m2. 1.2 Smooth - Non-absorbent surfaces Smooth and non-absorbent surfaces, as well as surfaces with bituminous membranes or other old waterproofing layers, must be primed with the water-based epoxy primer EPOXYPRIMER 500, thinned with water up to 30% by weight. The product is applied by brush or...
