PU Parquet Sealer
PU PARQUET SEALER is a two component sanding sealer based on plasticizing saturated polyester to provide a hard and flexible (even in high thickness application) basecoat for wood especially for parquet and wooden floors.
Appearance – Opalescent
Specific Gravity – 0.970 kg/L
Viscosity @ 25°C – 29” FC #4
Flash Point – 20°C
Non-Volatile (Wt.%) – Base 43.0 – Catalyst 40.0
Application Condition:
- Air Temperature – 5 -35°C
- Relative Humidity – 85% max.
Application Method – Brush, Spray, Roller
Recommended Catalyst – Catalyst #075
Thinner – PU Thinner #105/ 205
Mixing Ratio – Base 100 – Cat. 50 – Thinner 25-30
Pot Life – 3 – 4 hrs.
Drying Time (25°C)
- Dust Free – 20 – 25 mins.
- To Touch – 30 – 45 mins.
- To Recoat – 2 – 3 hrs.
- Hard Dry – 24 – 36 hrs.
- Sandable – 1 – 2 hrs.
Coating Rate – 6 – 8 m²/L
Recoating Interval – Min. of 30 min – max. 3 hrs. Light sanding with 400-600 grit sand paper is recommended before subsequent coat when recoating exceeds 3 hrs.
- Mixing ratio should be correctly observed.
- Paint should be used within the pot life after components have been mixed together. Pot life decreases at higher temperature.
- Bubbling due to 4 – 5 coat within relatively short time likely to occur in summer. 1 – 2 thin initial coat and longer recoating interval (50 – 60 min.) eliminates bubbling.
- Never leave the catalyst open.
