HZT12
HZT12 Hydrocrom white converter (30 gloss) — thixotropic waterborne white exterior enamel / tint base
White thixotropic one-pack waterborne enamel from the Milesi Hydrocrom line for wood that lives outdoors: windows, doors, cladding, fences, garden furniture. Holds on verticals without sagging, stays elastic, very good weather and UV resistance. Spray or brush over the white Hydrocrom impregnating primer; the certified system is two coats.
- Windows, doors and shutters
- Exterior cladding, boarding, trims
- Fences, gazebos, pergolas
- Garden furniture and outdoor joinery
- Tinted top coat (via HMT pastes)

Tinting the white base to colour (HZT12/COLOR).
No more than 15 % HMT paste (Milesi's stated maximum). Gloss depends on how much paste is added — do a test panel. Technocolor CH pastes are not stated for this product.

Brush — neat; spray — 0–5 % clean water only if the gun won't atomise it.
Clean (ideally demineralised) water only. Never S50/S80 or any solvent thinner.

Thixotropic: keep a wet edge, 50–75 % overlap. On flat horizontals it can orange-peel — drop pressure a touch, come a bit closer, cross-coat.

Best route for window/door runs: high transfer and good flow. Pump and hoses must be waterborne-rated (stainless).

Synthetic brush for waterborne; don't thin; don't overwork — the thixotropic enamel levels on its own.
Process and compatibility
- Substrate preparation
- Before impregnating, clean the wood of dust and dirt with Scotch-Brite. Sand with light pressure. Oak, chestnut and iroko contain extractives that retard drying and cause staining — use a suitable isolating primer. Exterior joinery moisture content 12–15 % (derived).dealer
- Goes over
- XHT111
- Goes over (alt.)
- XHC3recommended
- Sanding
- Impregnation — no sanding or a very light Scotch-Brite; between HZT12 coats — P320–P400, light pressure; no steel wool (it leaves rust spots under waterborne).recommended
- Temperature and humidity
- Don't apply below +10 °C or in high humidity.dealer
- Don'ts
- Don't thin with solvents — water only
- Don't apply below +10 °C or in high humidity
- Never sand with steel wool
- Don't exceed 15 % HMT paste
- Don't go over oak/chestnut/iroko without an isolating primer
- Don't let it freeze
Storage
- Storage temperature
- Do not freeze; close the tin tightly after use.dealer
- Shelf life
- approx. 12 months in the unopened original tinrecommended
Safety: Waterborne, non-flammable as a liquid; ventilate, and when spraying wear a particulate respirator (P2/P3), gloves and goggles. Don't pour waste down the drain.
