Description
ALSAN TRAFIK PU 122 is a two-component polyurethane-based resin, used as a primer on concrete.
Size - 18.6 gal
Material Use:
ALSAN TRAFIK PU 122 is a two-component, polyurethane-based primer designed for use on structural concrete substrates. It is primarily used to promote adhesion of polyurethane-based waterproofing and traffic coating systems, specifically within the ALSAN TRAFIK and ALSAN DECK systems. This primer is essential for ensuring long-term bond strength between the concrete substrate and subsequent coating layers.
System Components:
ALSAN TRAFIK PU 122 is used as the primer component in the ALSAN TRAFIK and ALSAN DECK systems. It may be used in conjunction with ALSAN TF 801 thickening agent when applied as a crack filler. The complete system typically includes:
- Primer: ALSAN TRAFIK PU 122
- Crack Filler (optional): ALSAN TRAFIK PU 122 + ALSAN TF 801
- Base Coat and Top Coat: Polyurethane-based resins from the ALSAN TRAFIK or ALSAN DECK product lines (not specified in this TDS but required for full system performance)
Applications:
ALSAN TRAFIK PU 122 is suitable for use on structural concrete surfaces in applications such as:
- Parking decks
- Balconies
- Plaza decks
It is not suitable for use on plywood or other non-concrete substrates.
Application Details:
- Surface Preparation: Concrete must be fully cured (minimum 28 days) with a compressive strength of at least 24 MPa (3500 psi) and a moisture content ≤ 4% (measured with a TRAMEX meter per ASTM F2659). Surface profile should be ICRI CSP 3 or 4, typically achieved via shot blasting. Cracks wider than 1.6 mm (1/16 in) must be repaired using SOPRASEAL SEALANT.
- Mixing Ratio: 2:1 by volume (Part A : Part B). Mix each part separately for 2–3 minutes, then combine and mix for an additional 2–3 minutes until homogeneous.
- Application Method: Apply immediately after mixing using a roller, flat squeegee, or foam squeegee.
- Recoat Window: The primer must be dry and tack-free before applying the next coat. The maximum recoat window is 36 hours.
- Pot Life: 30 minutes at 20 °C (68 °F)
- Curing Time: Fully cured in 4–5 hours at 20 °C (68 °F)
- Minimum Application Temperature: 5 °C (41 °F)
- Coverage: One 18.6 L kit (Part A + B) covers approximately 73.2 m² (788 ft²) at 250 µm (10 mils) wet film thickness
- Recommended Thickness: 250 µm (10 mils) wet film
- VOC Content: 18 g/L (0.15 lb/US gal)
- Solids Content: 100%
- UV Resistance: Not specified; as a primer, it is typically not exposed to UV and should be covered by subsequent layers
- Storage: Part A can be stored for up to 18 months, and Part B for 12 months, in original containers at temperatures above 10 °C (50 °F)
Special Notes:
- ALSAN TRAFIK PU 122 is not suitable for use on wood substrates such as plywood.
- When used as a crack filler, ALSAN TF 801 must be added after Parts A and B are mixed. Refer to the ALSAN TF 801 TDS for dosage and application instructions.
- All upstands (walls, columns, etc.) must be sealed with SOPRASEAL SEALANT prior to primer application.
- Ensure environmental conditions (temperature and humidity) are within specified limits during application and curing to avoid performance issues.
- The product is harmful if ingested, inhaled, or in contact with skin. Always refer to the SDS for safe handling practices.
This primer is a critical component in the ALSAN TRAFIK and ALSAN DECK waterproofing systems, ensuring strong adhesion and long-term durability of the full coating assembly on concrete surfaces.
