Interzinc® 72

Epoxy Zinc-Rich

All surfaces to be coated should be clean, dry and free from contamination. Prior to paint application all

surfaces should be assessed and treated in accordance with ISO 8504:2000.

Oil or grease should be removed in accordance with SSPC-SP1 solvent cleaning.

Abrasive Blast Cleaning

Abrasive blast clean to Sa2½ (ISO 8501-1:2007) or SSPC-SP6. If oxidation has occurred between

blasting and application of Interzinc 72, the surface should be reblasted to the specified visual standard.

Surface defects revealed by the blast cleaning process should be ground, filled, or treated in the

appropriate manner.

A surface profile of 40-75 microns (1.5-3.0 mils) is recommended.

Shop Primed Steel

Interzinc 72 is suitable for application to unweathered steelwork freshly coated with zinc silicate shop

primers.

If the zinc shop primer shows extensive or widely scattered breakdown, or excessive zinc corrosion

products, overall sweep blasting will be necessary. Other types of shop primer are not suitable for

overcoating and will require complete removal by abrasive blast cleaning.

Weld seams and damaged areas should be blast cleaned to Sa2½ (ISO 8501-1:2007) or SSPC-SP6.

SURFACE

PREPARATION

Material is supplied in two containers as a unit. Always mix a complete unit in

the proportions supplied. Once the unit has been mixed it must be used within

the working pot life specified.

(1) Agitate Base (Part A) with a power agitator.

(2) Combine entire contents of Curing Agent (Part B) with Base

(Part A) and mix thoroughly with power agitator.

Do not allow material to remain in hoses, gun or spray equipment. Thoroughly

flush all equipment with International GTA822. Once units of paint have been

mixed they should not be resealed and it is advised that after prolonged

stoppages work recommences with freshly mixed units.

Clean all equipment immediately after use with International GTA822. It is good

working practice to periodically flush out spray equipment during the course of

the working day. Frequency of cleaning will depend upon amount sprayed,

temperature and elapsed time, including any delays.

All surplus materials and empty containers should be disposed of in accordance

with approrpriate regional regulations/legislation.

Do not thin more than allowed by local

environmental legislation

In order to ensure good anti-corrosive performance, it is important to achieve a minimum system

dry thickness of 40 microns (1,5 mils). To achieve a uniform film at this thickness thinning at around

10% with International thinners will be required.

When applying Interzinc 72 by brush or roller, it may be necessary to apply multiple coats to

achieve the total specified system dry film thickness.

Surface temperature must always be a minimum of 3°C (5°F) above dew point.

This product will not cure adequately below 5°C (41°F). For maximum performance ambient curing

temperatures should be above 10°C (50°F).

Where Interzinc 72 is to be used as a primer for a coating system to be subjected to water

immersion, it is important to ensure that a minimum dry film thickness of 65 microns (2,5 mils) is

applied in order to provide adequate corrosion protection.

Over-application of Interzinc 72 will extend both the minimum overcoating periods and handling

times, and may be detrimental to long term overcoating properties.

Excessive film thickness may lead to splitting of the film when overcoated with high build systems.

In the event of Interzinc 72 being allowed to weather before being topcoated, it is important to

ensure that all zinc salts are removed prior to paint application, and recommended topcoats are

applied.

Interzinc 72 is not suitable for exposure in acid or alkaline environments.

This product has the following specification approvals:

• BS5493 (1977) : DF & KP1B

• BS4652:1995

• British Gas Specification PA9 and PA10

Note: VOC values are typical and are provided for guidance purpose only. These may be subject to

variation depending on factors such as differences in colour and normal manufacturing tolerances.
