NCL Bond

LATEX BASED ADMIXTURE

NCL Bond, an aqueous dispersion of carboxylated styrene butadiene copolymer. NCL Bond is a latex based admixture for use with cement combination, form as a toxic-free bonding agent for rendering, plastering, adhesive, tiling, repair mortar and as waterproof barrier.

ADVANTAGES

Greatly improved adhesion to substrates
Improved toughness and flexibility
Mixes may be applied in thin lay layers

Reduced water vapor transmission
Reduced dusting
Improved resistance to chemicals

APPLICATION

It is necessary to ensure that the substrate is free from dust, paint, oil, laitance etc., and damped before application of NCL Bond bonding agent.

A bonding slurry consists of two parts by weight of fresh cement to one part of NCL Bond thoroughly mixed to ensure a smooth blue-grey creamy consistency. This bonding slurry should be thoroughly brushed onto the prepared substrate, concrete, render or topping and should be applied while it is still wet.

Using NCL Bond latex admixture in place of water for repair mortar, tiling adhesive or render. Recommended dosage approximately 1.0 litre/m² and depends on site condition (Up to 5% water may be added to improve workability.)

STORAGE AND SHELF LIFE

12 months in air tight containers and stored in a cool ventilated area.

PACKING

Available in 20 kg container.

HEALTH & SAFETY

NCL Bond is hazard free. As with all chemical products, caution should always be exercised. Keep away from children.
