Nagambie Bypass (AbiGroup Constructors)
NK-TC 01 is a coating material that exhibits very high abrasion resistance, high chemical resistance and easy to clean surface properties. The coating material is applied to concrete and cement based substrates to give an opaque satin-gloss or matt finish. The coating provides excellent long-term protection against concrete cancer and corrosion. The coated surface also behaves as an excellent anti graffiti surface, whereby environmentally friendly citrus clean-ers can be used to effortlessly remove repeated graffiti attacks.
Features include : * One coat or two coat wet on wet process (no priming) * Exceptionally strong bond with con-crete * Excellent hiding characteristics on both concrete and old coatings * High weather resistance * UV stable * Stable against salt spray * Excellent carbon dioxide resistance * Excellent water vapour diffusivity * Hydrophobic, self cleaning surface * Excellent barrier to water ingress * Excellent barrier to chloride ions * Excellent anti-graffiti performance.

Delivery form: 2 part product (Part A + Part B)
Finish & Colour: Satin or Matt. White, Grey, Yellow, Red (additional colours possible)
Type of binder: Polysiloxane-Polyepoxy-Resin
Solids-content: > 95 % by weight
Density: 1.59 kg / dm³ (Part A), 0.99 kg / dm³ (Part B), 1.5 kg / dm³ (Mixture)
Theoretical spreading rate: 7.92 – 4.75 m²/kg at 120 to 200 microns dry film. Practical spread rate will depend
on the method of application and the surface roughness.
Thermal resistance: -20 °C to +150 °C
Shelf life: At least 12 months in closed original can, stored in cool, dry conditions.
Surface treatment: NK-TC 01 can be applied mechanically or manually in a single process (single coat
or wet on wet application) without using a primer. The surface must be dry and free of dirt, dust and grease. Loose impediments must be removed before coating application. On cracked surfaces crack-closing pre-treatment is necessary. A small test square should be applied first in all instances.
Application: Substrate temperature: Min. +5°C, max. + 30°C
Air temperature: Min. +3°C, max. + 30°C
Relative humidity: Max. 95 %
Mixing: Part A : Part B = 6 : 1 by weight
Part A must be stirred before the addition of Part B. After addition of Part B the mixture must be stirred well for about 5 minutes or until the coating material is homogeneous. Application with airless-spraying, rolling or brush. Tools must be cleaned immediately after use with thin-ner.
Thinning: NK-TC 01 can be thinned up to 10% with an industrial two pack epoxy thinner.
Potlife (25°C): 4 hours
Drying times (25°C): Touch : 2 hours ; Through : 16 hours ; Full cure : 7 days
Coating thickness : WFT 138 micron = DFT 120 micron ; WFT 230 micron = DFT 200 microns
VOC : 63.57 g/L
