Construction instructions

Airless spray nozzle pressure: 12-18 MPa 

Nozzle aperture : 0.41-0.58 mm 

Spraying angle: 40-80 Spend

Dilution ratio: 0-3% (volume ratio)

Air spray not suitable

Brush or roller coating is only recommended for pre-coating and small area coating, but the specified dry film thickness must be achieved . 

Dilution ratio: 0-3% (volume ratio )

Thinner / Cleaning Agent 601 Special diluent

Avoid adding excessive amounts of thinner, which will reduce sag resistance and extend curing time.

(1)The data is for reference only. The actual drying time and recoating interval depend on factors such as paint dry film thickness, ventilation, humidity and previous paint.

(2)The surface must be dry and free of dirt before recoating. The adhesion of subsequent coatings is best when the previous coating is completely cured. If the coating is exposed for a long time, the surface must be roughened before recoating to ensure adhesion between the coatings.


Surface treatment

Painted surfaces must be dry; remove all grease with solvent as specified in SSPC-SP1 ; remove salt and stains with clean water. Corroded areas must be repaired with a suitable primer / tie coat.


Construction conditions

The surface temperature of the substrate should be at least 3 °C higher than the air dew point temperature, and the relative humidity should not exceed 85% (the temperature and relative humidity should be measured near the substrate).

The surface temperature of the substrate should not exceed 40°C . Otherwise, a suitable spraying method should be selected and appropriate diluent should be added as required to prevent dry spraying. In extreme cases, the dry film thickness of the coating can be appropriately reduced to prevent sagging.

The paint temperature must be above 15 °C, otherwise thinner should be added to achieve the required viscosity for construction.


Recommended Package

The following is a typical high performance coating system for newbuildings (antifouling period 24 months):

TO1.26 Aluminum powder chlorinated rubber anti-rust paint

2 × 50μm

(Dry film thickness)

TO1.25 Iron Red Chlorinated Rubber Anti-Rust Paint

1 × 75μm

(Dry film thickness)

839 long-lasting antifouling paint

2 × 80μm

(Dry film thickness)

Note: The dry film thickness of antifouling paint depends on the actual navigation conditions of the ship and the antifouling period.


Store

Must be stored in accordance with national regulations. The storage environment should be dry, cool, well-ventilated, avoid high temperatures and stay away from fire. The packaging container must be kept sealed. The storage validity period is at least 12 months.
