DESCRIPTION

Coldseal 200/90 is a cold applied, two part modified polyurethane cold applied sealant for sealing joints in concrete paved areas, roads, bridge decks, airfield runways and warehouses. It is capable of accommodating above average movement, and severe climatic conditions. Coldseal 200/90 is highly adherent to most materials commonly used in construction. It is available in pouring grade only. Coldseal 200/90 is resistant to fuel, oil and hydraulic fluid spillage, will not harden in cold weather nor become excessively soft or pick up in hot conditions. Coldseal 200/90 has high durability and a long service lift which significantly reduces maintenance costs.

 

Uses

Coldseal 200/90 has been specifically developed for sealing contraction and expansion joints in internal and external concrete slabs where resistance to attack by fuel and oils is required.

 

Advantages

1. Cold applied – no heating equipment required.

2. Fuel, oil and hydraulic fluid resistant.

3. Self levelling.

4. Tough rubbery seal, tolerant of climatic variations.

5. Improved sealing efficiency – less maintenance.

6. High movement accommodation.

7. Pitch free – environmentally friendly.
