Steel supports are welded

on each tank dished-end.

Installation of the tank

on a rotating unit

The tank is set on a rotating mandril.

Equipment required to apply Endoprene

Manual or automatic, a two-component hot airless spray equipment is required to apply Endoprene paints.

Our Technical Departement can help you find out the nearest supplier.

ENDOPRENE

• Product temperature: - Part A (polyol) 60°C - Part B (isocyanate) 25°C

• Pump ratio: mini 40/1

Two-component hot « AIRLESS » spray

equipment required to apply Endoprene

ENDOPRENE

• Start up the application equipment at least 60 min. before application to allow for the Endoprene part A to heat up to 30°C.

• Check pressure gauges: air pressure between 4 to 6 Kg/cm²

Two-component hot « AIRLESS » spray equipment

ENDOPRENE

Standard conditions of application need to be

checked before the application

• Relative humidity : min. 5% - max. 80%

• Air temperature : min.+5°C - max. 40°C

• Substrate temperature : min. 10°C max. 40°C*

*(3°C above dew point)

ENDOPRENE

Stripe coats

Application of a stripe

coat over welding

areas and sharp edges

to provide additional

thickness over

critical areas.

The line between the

gun and the mixing unit

should not exceed

3 meters.

ENDOPRENE

Safety regulations

Application in a suitable

paint shop conformed

to health and safety

current regulations with:

- Air extractors or water wall

- Industrial filters

- Paint mask for the painter

ENDOPRENE

Application

While the tank rotates, application of

one coat (several passes wet on wet)

between 500 µ and 1500 µ up to

specifications.

Starting the application from one of

the dished-end towards the other end.

ENDOPRENE

Foward progression with 50%

overlapping passes, wet on wet.

Application process

Ideal surface tank rotation

speed: 24 meters/min

(3 to 5 rotations per min.)

ENDOPRENE

Application process

• Spraying distance to the tank

surface 20 to 30 cm

Spray gun tip size: 21 to 31/1000 ”

spray angle: 60°

Wet film thickness

Control

Solvent-free product means:

Wet film thickness = Dry film thickness

(800 microns for EU standard)

ENDOPRENE

Wet film gauge

ENDOPRENE

Mixing unit

Mobile mixing unit, allowing the

painter to move freely.

The heated line to the dosing pump

should be 20 meters long.

Endoprene 868.06 at 800 microns

D.F.T. (European Specification) for

a typical 50m3 tank.

ENDOPRENE

Drying process

The tank keeps on rotating after

application to accelerate drying

time.

Touch dry at 20°C : 20 min.
