UVA Topcoat 500ml/16oz 485/1.05lbs Transparent Matte

The H6 SI44 UVA Topcoat forms an ultra-hard, glass-like, and hydrophobic protective layer that provides superior resistance against even the most aggressive chemicals—including hydrofluoric acid (HF), hydrochloric acid, citric acid, and red wine—while remaining completely food-safe.

With medium hardness and medium flexibility, it is especially suitable for surfaces that require a small degree of stretch, maintaining excellent adhesion and durability even on slightly flexible substrates.

Recommendations

A fully cured H9 SI44 UVA layer can only be removed by sanding the surface with ceramic sandpaper (recommended grit: P800–P1200, depending on the surface condition).

Easy to Apply

Application; 1. Clean the surface 2. Sterilize the surface (acetone)  3. Apply via the cotton pad one even layer or use a (HLVP) Spray-gun for multiple layers wet on wet. 4. Let it cure.

Curing:

Ambient Curing:

The ideal temperature range is typically between 20°C / 70°F and 35°C / 95°F.

Humidity:

The relative humidity should be preferably below 70%. 

Curing Time:

Complete curing time is approximately 5 days; after this period, the curing can be checked.

Heat Curing:

Cure at 120°C / 250°F  for 1.5 hours.

Verify that the coating is completely cured after heating in the oven.

To check curing, press your finger firmly on the coated surface. No material should stick to your finger.

Curing by Hot Air Blow:

Set the hot air gun temperature to 120°C / 250°F  to 130°C / 265°F and apply for 3 to 4 minutes.

Approximately 80% to 90% curing can occur within 3 to 4 minutes. After this, the surface will be dry. Full curing requires 24 hours.

Stacking should be avoided until full curing is achieved.

Storage and handling

Store in dark and dry conditions at room temperature.

Use gloves and mask.
