Market Segments

H3 SI54 UVA is a highly flexible and stretchable coating designed for surfaces exposed to movement, vibration, and extreme environmental conditions. It offers outstanding UV resistance, durability, and adhesion—making it a versatile solution across multiple industries, including:

• Building Protection – Ideal for waterproof roof coatings on flat concrete buildings, providing a flexible and weather-resistant barrier.

• Tarpaulins & Truck Covers – Delivers long-lasting elasticity and protection against UV radiation, dirt, and mechanical stress.

• Marine Applications – Ensures durable, waterproof protection for flexible substrates exposed to saltwater and sunlight.

• Caravans & Recreational Vehicles – Maintains elasticity and surface integrity under varying temperatures and outdoor exposure.

• Industrial Coatings – Improves flexibility and chemical resistance on acrylic, epoxy, polyester, and polyurethane systems.

Reachable Area

12.5ml/m² (0.04oz/ft²) for one layer (roll, wipe or spray) with a thickness of around 6 microns. 1L covers up to 80m² (32oz - 800ft²).

Coverage may vary depending on coating thickness. Can be sprayed wet on wet to create thicker layers.

Recommendations

A fully cured H3 SI54 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.
