High performance cellulose ether cement render additive can drive down application time and costs

Dow Construction Chemicals : 04 April, 2011  (New Product)
Manufacturers of cement-based renders looking to improve on site workability of their products
With increasing pressure for contractors on construction sites to deliver against ever tighter time and cost margins, materials which can deliver fast yet reliable results will be welcomed.

Walocel MKW cellulose ethers address the four key attributes vital to an effective, efficient cement-based render:

* Air void stability, meaning mortar maintains its density and consistency during application.
* Good workability so that mortar can spread and level easily without sticking to tools.
* Temperature tolerance in order that mortar can retain water and not dry out before it has properly cured.
* Minimal retardation to reduce curing times and support efficiency on site.

Cellulose ethers are designed to support manufacturers in a number of ways which helps deliver high performance cement render products with their targeted technical properties.

* Air voids in the render lower its density, making it smoother and improving its workability. Walocel MKW cellulose stabilises trapped air, which helps maintain the consistency of the render and prolongs the open time. This extends the time frame for leveling after spraying and enables users to work more effectively during consecutive spraying and leveling stages.

* Cellulose ethers also support good workability through an optimum balance between standing strength (which helps prevents sagging) and shear stability (which supports levelling), while at the same time maintaining low ‘stickiness’.

In order to harden properly, a render must retain water during curing, develop to its full strength and ensure cement hydration. Walocel MKW cellulose ethers have been designed with water retention properties that operate at temperatures as high as 40C. This supports extended open time, good workability and effective curing across a range of geographic regions.

Cellulose ethers have been specially engineered to minimize retardation and deliver shorter curing times, even at temperatures as low as 10C and below. Users benefit from increased efficiency on job sites thanks to a reduction in delays between initial application of render and final surface treatment.
