DISBON DisboPUR 309 5kg

DisboPUR 309 2K-PU Sealer – transparent and silk-matt, 5 kg / 10 kg

DisboPUR 309 is a solvent-based, transparent 2-component polyurethane sealer that gives epoxy resin and polyurethane coatings a silk-matt, slightly textured surface. The sealer is abrasion-resistant, easy to clean, and suitable for chair casters. At approx. 0.15 kg/m², 5 kg is sufficient for approx. 33 m² and 10 kg for approx. 66 m² per application.

In combination with yellowing-resistant PU coatings, DisboPUR 309 can also be used outdoors, e.g., on balconies.

Advantages

• Matts glossy EP and PU coatings – silk-matt look
• Abrasion-resistant (Taber abrasion < 45 mg)
• Easy to clean
• Suitable for chair casters (medium mechanical load)
• Resistant to water, detergent solutions, diluted salt solutions, mineral oils, and petrol
• Can also be used outdoors with yellowing-resistant PU systems

Areas of application

• Sealing of epoxy resin floor coatings
• Sealing of tough-hard and elastic PU coatings
• Residential, office, and commercial spaces
• Balconies (on yellowing-resistant PU coatings)

Application

1. Preparing the substrate

Seal fresh EP or PU coatings within 24–48 hours. Deep clean and lightly sand older, fully reacted coatings. Preliminary adhesion tests are recommended.

2. Mixing

Stir part A, add part B (3 : 1), and mix with a slow-running agitator (max. 400 rpm) until streak-free. Transfer to another container and mix thoroughly again.

3. Applying

Apply quickly using a lint-free mohair or velour sealing roller, without rolling back into material that has already begun to react. Distribute with a saturated roller and finish structuring with a "dry" roller – work with at least two people on larger surfaces.

4. Allowing to cure

Protect from moisture for about 18 hours. Walkable after 18–24 hours, resistant to water after approx. 7 days.

Application conditions: Material, air, and substrate temperature 10–30 °C, rel. humidity max. 75 %, substrate at least 3 °C above dew point. Do not apply in direct sunlight or draft.

Compatible with: DISBON DisboFLOOR 475 SL.
