Ilva TW18 is a clear water-based self-sealer formulated for professional use on timber and engineered wood substrates. It is designed for both light and dark hardwoods, non-resinous softwoods, and fine-line or reconstituted veneers.
TW18 combines the properties of a sealer and topcoat in one product, reducing application time while maintaining excellent clarity, sanding performance, and durability. It delivers a smooth, natural finish with fast drying and low odour, making it suitable for interior furniture, panels, and joinery.
The coating can be used as a single-component (1K) system or as a two-component (2K) system when catalysed with Ilva TXW13 water-based hardener for enhanced chemical and mechanical resistance.
Mixing Ratio (2K use):
By Weight: 100 parts TW18 + 5 parts TXW13 Hardener
By Volume: 100 parts TW18 + 4.4 parts TXW13
Pot Life: 2 hours at 20°C
Viscosity (ISO 6 Cup): 94 ± 5 seconds (ready to spray)
Solid Content (mixture): ~22.5%
Thinning:
If required, thin with up to 5% clean water to adjust flow or viscosity.
Stir well before and during use to maintain uniform consistency.
Application Methods:
Suitable for airmix spray, curtain coater, or hand spray application.
Apply 110–140 g/m² per coat (approx. 4.2–5.4 wet mils).
