This is a two

component

polyamine cured

epoxy mastic coating.

I t

is a surface

tolerant

high solids product. Specially designed

for

areas where

optimum

surface preparation is

not

possible

or

desired.

Can

be used

as

primer mid coat finish coat

or

as single coat

system in atmospheric and immersed

environments. Suitable

for

properly prepared

carbon steel and aged coating surfaces.

This is a

two

component chemically curing

aliphatic acrylic polyurethane coating. t has

a matt finish

with very

good gloss retention.

It is a high build product. To be used as

topcoat

in atmospheric environments.

Use

airless spray.

Recommended

for

stripe coating and small

areas. Care

must

be taken

to

achieve the

specified

dry

film thickness.

1. All oil/grease, dust and other contaminant to surface shall be

remove/wash by fresh water with 250 bar pressure at nozzle. add

detergent if necessary to remove oil/grease)

2

All surfaces prepared

for

coating shall be abrasive blast clean in

accordance with the Swedish Standard SIS 05 5900 or the

following:

The profile roughness achieved shall be between 30 - 85 microns

as measured using Keane Tator Surface Profile Comparator or 0

testex film and profile gauge.

4. Abrasive used for blast cleaning should be dry and free from dirt oil

and grease and suitable

for

procuring the standard of cleanliness

and profile specified.

5. After blast cleaning removes loose adhering dust, debris and

abrasive material from surface by use of high pressure

1.

The

temperature

of

the

substrate should be

minimum

10°C and

at

least 3°C above the dew point of the air, temperature and relative

humidity

measured in the vicinity

of

the substrate maximum 85 .

Good ventilation is usually required in confined areas

to

ensure proper

drying. The coating should not be exposed

to

oil, chemicals or

mechanical stress until cured

2 All Paint should

be

applied by airless spray except for stripe coats

where brush or roller should in general be used.

3. Efficient mechanical stir rers

or

power

mixer for

the correct mixing

of

paint

should

be

used 7 wooden stick or something like

that is strongly

forbidden to use.

4. Available air pressure and capacity for spray

equipment

should be at

least 5.5

kg/cm2

and 1.4 m3 90

100

Psi and 50 Cfm).

5 Airless spray equipment

must

be in good working order and be capable

of performing to be out put requirements defined

in

the Jotun data

sheets.

6.

It

is recommended

that

pump ratios

for

45: 1

or

greater.

7. Tips should be the size stipulated on the product datasheets or as

agreed with the Jotun paint representatives on site. Tips should not be

in a worn condition.

8. Only thinners and additives supplied by or acceptable to Jotun are

to

be used and they are not to exceed the quantity recommended. Only

solvents acceptable by Jotun are to be used for cleaning equipment.

9. Re-coating

time

must

be

TECHNIC LINSPECTION

1.

Dry film thickness: each coat

must

be checked when

the paint

is dry.

f

the dry film thickness is lower than owner s specification, build up

thickness must

be

done to achieve minimum OFT requirement.

2. After exposure and contaminated with the environment surface shall

be fresh water washed and prepare clean before any coating

application.

3.

f

the maximum re coating interval exceed, roughening of the surface

by sandpaper and or light abrasive sweeping is mandatory.

4. Note batch

number of

paint (Comp. A and B on the log book.

VI

STORAGE

All paint and thinner shall be kept closed in original, undamaged can

before use and stored under shelter, away from direct sunlight, to keep

the air temperature below 25 C is the best recommendation, Any paint
