INTERTHANE 1070 PART A INDIVISIBLE KIT

What it is and why choose it

INTERTHANE 1070 PART A INDIVISIBLE KIT is the base component of a two-component, high build, acrylic polyurethane primer/finish. Formulated with zinc phosphate anti-corrosive pigmentation, it offers excellent durability, long-term recoatability and an attractive semi-gloss finish. Designed to be applied direct to metal as a one-coat primer/finish, it combines barrier corrosion protection with long-term cosmetic performance in moderately corrosive environments (for example C3 category, as defined in ISO 12944-2:1998).

Main features

• Two-component acrylic polyurethane system with high build properties.
• Acts as both primer and finish in a single coat for direct-to-metal applications.
• Contains zinc phosphate anti-corrosive pigmentation for enhanced barrier protection.
• Semi-gloss appearance for a clean, cosmetic finish.
• Good durability and extended overcoating intervals for long-term maintenance flexibility.
• Suitable for airless spray, air spray, brush and roller application.
• Developed specifically as a direct-to-metal coating.
• Intended for use by professional applicators in industrial environments.

Applications and use cases

INTERTHANE 1070 PART A INDIVISIBLE KIT is intended for use as part of the Interthane 1070 system in the following situations:

• One-coat primer/finish for direct-to-metal applications where both corrosion protection and a semi-gloss cosmetic finish are required.
• Structures and equipment located in moderately corrosive environments (C3 category as per ISO 12944-2:1998).
• Industrial steelwork where high build is desired in a single application by airless spray.
• Maintenance and repair projects where long overcoating intervals and good recoatability are important.

Suitable topcoats over Interthane 1070 include Interthane 990 and Interthane 1070, depending on the specified coating system.

FAQ

1. What type of product is INTERTHANE 1070 PART A?

It is the base component (Part A) of a two-component, high build, acrylic polyurethane primer/finish containing zinc phosphate anti-corrosive pigmentation.

2. Can Interthane 1070 be used as a single-coat system?

Yes. It is suitable for use as a one-coat primer/finish for direct-to-metal applications, especially when applied by airless spray to achieve the specified high film build.

3. In what environments is this coating recommended?

It is ideal for moderately corrosive environments, for example those classified as C3 category in ISO 12944-2:1998.

4. Which application methods are supported?

It can be applied by airless spray, air spray (including pressure pot), brush or roller. Maximum film build in one coat is best achieved by airless spray.

5. Is thinning required?

Thinning is not normally required. If necessary under extreme conditions, only International GTA713 or GTA056 thinners should be used, and not in excess of local environmental limits.

6. Can it be applied at low steel temperatures?

It should not be applied at steel temperatures below 5°C (41°F).
