IYSPUR PROOF RC 2K
Product Information
PRODUCT DESCRIPTION
IYS PROOF RC 2K is a fast-curing, two-component, bitumen-enriched polyurethane-based liquid material. It adheres strongly to almost any surface, forming a highly elastic film.
It offers excellent chemical and mechanical resistance.
Its composition is based on fully elastomeric hydrophobic polyurethane resin, supported by chemically polymerized pure bitumen.
It is applied with a minimum consumption of 1.5 lt/m² using a brush, roller, spatula, or airless spray equipment. The mixing ratio of the components is 1:1 by volume.
APPLICATION AREAS
- Floors
- Foundations
- Roofs
- Green roofs and plant beds
- Gypsum and cement panels
- Polyurethane insulation foams
- Asphalt membranes/EPDM membranes
- Bathrooms (under tiles)
- Patios and balconies (under tiles)
- Lightweight roofs made of metal or fiber cement
- Water tanks (except drinking water reservoirs)
- Bridge decks
- Open/Close tunnels
- Irrigation canals
Product Description
LIMITATIONS
- Not recommended for applications on unstable substrates or areas exposed to UV rays.
FEATURES AND ADVANTAGES
- Easy mixing: The components are mixed in equal amounts, 1:1 by volume.
- Fast curing.
- Can be applied in thick layers without bubbling.
- Unmixed components can be saved for later use.
- Excellent crack-bridging capability due to its low modulus.
- Adheres perfectly to almost every surface, with or without primer.
- No thinning required, but ELAPUR SOLVENT can be used depending on conditions.
- Excellent thermal resistance: The product will never soften. Maximum service temperature is 80°C, and maximum shock temperature is 200°C.
- Cold resistance: The film retains its elasticity down to -40°C.
- Superior mechanical properties: High elongation, tensile strength, tear resistance, and abrasion resistance.
- Good chemical resistance.
APPLICATION DETAILS
Suitable Surfaces: Concrete/steel reinforced concrete, fiber cement, mosaic, cement-based roofing tiles, old but well-adhered acrylic and asphalt coatings, wood, corroded metal, and galvanized steel surfaces. For other substrates, please contact our technical department.
Concrete Substrate Standards
- Hardness: R28 = 15 Mpa
- Moisture: W < 10%
- Temperature: 5-35°C
- Relative Humidity: < 85%
SURFACE PREPARATION
- The surface should be cleaned using high-pressure washing, removing oil, grease, fuel, and paraffin residues. It should also be free from mold release agents, cement residues, shavings, loose particles, and cured membranes.
Priming
- Use the appropriate primer as recommended in the options list.
MIXING
- Mix the two components in equal amounts by hand or with a low-speed mixer (300 rpm) and apply immediately. The pot life of the mixture at 20°C is 30-45 minutes.
CONSUMPTION
- Minimum consumption: 1.5 lt/m²
For airless spray applications, especially with low-powered machines, it may be necessary to thin the mixture with a small amount of ELAPUR SOLVENT.
Crack Bridging
- Before applying the main layer, apply IYS PROOF RC 2K or IYS PROOF RC 1K to cracks wider than 1 mm.
APPLICATION
- Apply with a brush, roller, spatula, or airless spray equipment.
CLEANING
- Clean tools and equipment first with paper towels, then with ELAPUR SOLVENT. Rollers cannot be reused.
PACKAGING
- 2×20 lt and 2×200 lt
SHELF LIFE
- The product can be stored in unopened original containers in dry environments at temperatures between 5°C and 25°C for a minimum of 12 months. The containers of unmixed components should be tightly sealed and stored for later use.
SAFETY PRECAUTIONS
- Contains low levels of volatile flammable solvents. Do not smoke during application, and work in well-ventilated areas away from open flames. Continuous ventilation should be provided in enclosed spaces, and activated carbon masks should be worn. Solvents are heavier than air and will accumulate at ground level. Please request the Safety Data Sheet (SDS) from your supplier.
