Description
One component aromatic polyurethane resin available in grey and dark grey.
UNITS PER SKID: 36
VOLUME: 19L
Material Use:
ALSAN TRAFIK HP 520 is a one-component, self-leveling polyurethane resin designed for use as a waterproofing membrane in vehicular and pedestrian traffic areas. It is specifically formulated for use in parking decks, balconies, and plaza decks, providing a durable and flexible waterproofing layer.
System Components:
ALSAN TRAFIK HP 520 is used as part of a multi-layer waterproofing system. It must be applied over one of the following primers: ALSAN TRAFIK PU 122 or ALSAN FLOOR EP 101. These primers ensure proper adhesion to the substrate. An optional additive, ALSAN TRAFIK HP ACCELERATOR, can be incorporated into the resin to accelerate curing times, especially in cooler temperatures.
Applications:
This material is ideal for waterproofing exposed concrete surfaces in high-traffic areas such as parking structures, balconies, and plaza decks. It is suitable for both vehicular and pedestrian traffic zones where flexibility, durability, and waterproofing are essential.
Application Details:
Before application, the selected primer must be dry to the touch, and the maximum recoat time of the primer must not be exceeded. ALSAN TRAFIK HP 520 should be mixed for 2 to 3 minutes to achieve a homogeneous consistency. It is applied using a notched squeegee at a wet film thickness of 710 µm (28 mils) and then leveled with a roller for even distribution. A 19 L (5 US gal) container covers approximately 285 ft² at the specified thickness, equating to a coverage rate of 57 ft² per gallon.
Curing Time and Pot Life:
Curing times vary with temperature and humidity. At 22 °C (72 °F) and 50% relative humidity, the material is:
- Set to touch: 3.5 hours
- Tack-free: 8.5 hours
- Dry-hard: 15 hours
- Dry-through: 22 hours
With the addition of ALSAN TRAFIK HP ACCELERATOR, curing times are significantly reduced, especially at lower temperatures (e.g., set to touch in 40 minutes at 5 °C).
Environmental and Application Limitations:
- Temperature Range for Application: Do not store or apply below 10 °C (50 °F).
- Humidity: Application should be done in dry conditions; high humidity may affect curing.
- Maximum Recoat Time: 36 hours.
- UV Resistance: Not explicitly stated; additional topcoat may be required for UV stability in exposed applications.
- Storage: Up to 18 months in original, unopened containers stored above 10 °C (50 °F).
- Viscosity: 1,500 – 3,500 cP at 25 °C.
- Solid Content: 75%.
- Elongation at Break: 600% (ASTM D412).
- Tensile Strength: 8 MPa (1160 psi).
- Hardness (Shore A): 80.
Special Notes:
- ALSAN TRAFIK HP 520 must always be used in conjunction with an approved primer (ALSAN TRAFIK PU 122 or ALSAN FLOOR EP 101).
- The use of ALSAN TRAFIK HP ACCELERATOR is recommended in cooler conditions to maintain reasonable curing times.
- Ensure even application to avoid thin spots, which may compromise waterproofing performance.
- Not intended for use as a standalone UV-exposed topcoat unless otherwise specified by the manufacturer.
- Always consult SOPREMA technical representatives for complete system design and compatibility with other ALSAN TRAFIK components.
