Protal 7000 & 7200

Field Application Instructions

1. Clean exposed steel and adjacent pipe coating with

non-oily solvent cleaner (i.e., ethanol, MEK, etc.)

2. The substrate temperature range for application of

Protal 7000 or 7200 is 50ºF (10

ºC) to 185

ºF (85

ºC).

The substrate temperature must be a minimum of

5ºF (3

ºC) above the dew point temperature before

proceeding with the coating operation. If the

ambient temperature is below 50ºF (10

ºC) the

substrate shall be heated.

PRE-HEATING:

Propane Heating: All surfaces to be coated shall

be grit blasted to a near white finish (SSPC SP-10,

NACE 2 or Sa 21/2). Edges of the existing coating

shall be roughened by sweep blasting the coating

for a distance of 25 mm minimum. Preheat the pipe

with a propane tiger torch up to 200ºF (93

ºC) or the

desired temperature. The temperature can be

checked with a magnet thermometer or Raytek

Temperature Gun. Hot sticks are not recommended

and shall not be used to check the temperature of

the substrate. Once the desired temperature is

achieved, the surface to be coated shall be sweep

blasted to remove any contaminants.

Induction Coil Heating: All surfaces to be coated

shall be grit blasted to a near white finish (SSPC

SP-10, NACE 2 or Sa 21/2). Edges of the existing

coating shall be roughened by sweep blasting the

coating for a distance of 25 mm minimum. Place

the induction coil around the pipe and heat to 185ºF

(85ºC) or the desired temperature.

3. Wipe clean with a lint-free cloth or air blast the

substrate. Surface must be clean and dry prior to

the application of the Protal coating.

4. Mix separately with a stir stick Part A and B prior to

mixing products together. Pour contents of Part B

Hardener (small container) into Part A Resin (large

container). Scrape walls and bottom of Part B to

ensure all hardener has been used. All kits are pre-

measured quantities therefore do not add additional

Part B Hardener as this will effect the quality of the

mixed coating. At no time shall thinner be added.

MIXING:

Stir Stick: Begin mixing Part A and B together until

a uniform color mix is achieved (approximately two

minutes). During mixing, careful attention should be

made to ensure the walls and bottom are scraped

and mixed thoroughly. No streaks should be visible.

Power Mixer: Begin mixing Part A and B together

at a speed that ensures a uniform color is achieved

(approximately two minutes). Avoid moving paddle/

mixing tip in an up and down motion, as this will

introduce air into the product. During mixing, careful

attention should be made to ensure the walls and

bottom are scraped and mixed thoroughly. No

streaks should be visible.

5. Application shall take place immediately after

mixing. POUR the product onto the surface and

spread down and around with a brush, 6mm nap

roller or Denso applicator pad. DO NOT APPLY

THE PRODUCT BY DIPPING THE BRUSH OR

APPLICATOR INTO THE BUCKET. Spread the

coating in bands beginning from twelve o’clock to

six o’clock on each side of the pipe while overlap-

ping strokes at both top and bottom. The Protal

coating shall be applied at the specified Dry Film

Thickness (DFT) up to 1000 microns. The

average wet film thickness is typically applied 635-

760 microns in one coat. Wet film measurements

shall be taken during application to ensure close

adherence to the specified thickness.

For detailed instructions please see “Protal Hand

Application Specifications”.

Pipeline Integrity is rapidly becoming a major factor for pipeline companies in North America. Pipeline companies, by law, must operate safe pipelines and provide documentation to prove that all external corrosion defects are controlled from adversely impacting structural integrity. The cost impact due to a failure is not an option.

coat), and is environmentally safe.Denso manufactures a full line

of Protal liquid coatings to meet the demand of the pipeline industry. Protal liquid coatings are the coatings of choice by owners, oil and gas specifiers and contractors across North America.

With thousands of miles of buried pipelines constructed and coated well over 50 years ago, in many instances, the old coating has gone well past its useful service life. Denso’s Protal 7200 is fast becoming the product of choice for recoating these pipelines in the field.

Recently, Columbia Gulf Transmission selected the Protal 7200 to recoat approximately 2.4 kms of 75 and 90 cm diameter pipe. The project consisted of excavating and exposing the pipe in the ditch and removing the original coal tar epoxy coating. Prior to recoating, the pipe was sandblasted to a near white metal finish, SSPC SP-10 or NACE No. 2 standard. After the surface was prepared, the Protal 7200 was applied using plural component spray equipment. The coating was applied by the Mears Group at an average thickness of 685 – 865 microns in one coat. The tack-free time was approximately 30 minutes

Protal History Denso has been developing and manufacturing pipeline coatings since 1929. In 1990 Denso pioneered the first 100% solids epoxy used for girth welds and rehabilitation of pipelines in North America. Protal 5900 was the first high build, fast cure and environmentally safe coating available in the market. In 1994, continued research and development lead to the introduction of the Protal 7000 Series. This product series featured higher build and faster curing characteristics. Our most recent development is our Protal 7200 Series, which leads the industry in cathodic disbondment results and curing times. Since the introduction of our Protal Liquid Coatings, Denso has sold over 1,000,000 litres of coating.
