Product Description

Flowdur Primer TC is a three-component solvent free polyurethane resin adhesive primer for use as a bonding aid for polyurethane resin based screed compositions including Flowdur WR, CG, SC and Flowbulk. Flowdur Primer TC is designed to be tacky to enable trowel applied resin screeds to be applied wet on wet giving a monolithic bond. 

Resin products 
should not be mixed or applied outside of the range of 10 - 25 °C. The substrate and uncured floor must be kept at least 3°C to reduce the risk of condensation or blooming on the surface, from before priming to at least 48 hours after application. 

Coverage*

Coverage varies widely due to the porosity and profile of different substrates. As a guide, a coverage rate of 2.5 - 4 m2/kg should be estimated per coat depending on substrate quality.

*Coverage figures given are theoretical. Practical coverage rates may vary due to wastage factors and the type, condition, profile and porosity of the substrate. 

Typical Properties, 28 days at 20 °C

Adhesion to concrete (BS EN 1504-2) (concrete failure) > 1.5 MPa

The typical physical properties given above are derived from testing in a controlled laboratory environment. Results derived from testing field- applied samples may vary dependent upon site conditions.

Cure Schedule at 20 °C

Working life of full packs * 15 minutes

* Usable working life of material following mixing and immediate spreading as per the application instructions. The topping must be applied when Flowdur Primer TC is still tacky. At 20°C this will be between 1.5 hours and 2 hours after the primer has been mixed. Work should be organised around this window. Colder temperatures will reduce the rate of cure and warmer temperatures will increase the rate of cure. Do not use below 10 °C. If the primer is allowed to become tack free, a further coat of Flowdur Primer TC must be applied within 24 hours. If the over coating interval is exceeded, the first coat should be abraded to ensure inter-coat adhesion.
