Product Characteristics

Description

Hempel Epoxy Zinc-rich Paint 1534C is a two-component polyamide-cured epoxy zinc-rich paint. Cures to form a strong anti-corrosive coating. This product complies with the composition requirements of HG/T 3668-2020 Type II Class 3.

Recommended use

Suitable for immediate application on containers. According to a separate coating specification, it can be used as an epoxy zinc primer for other purposes.

Service temperature

• Under dry conditions: maximum service temperature 140 °C [284 °F].

Product features

• Good application performance.

• Good mechanical properties.

VOC content (after mixing the multi-component paint)

Subject to specific legislation; see the explanatory notes on the Hempel website hempel.com or your local Hempel website. VOC values may vary with colour; refer to Section 9 of the Safety Data Sheet. This product complies with the VOC requirements of national mandatory or recommended standards; consult the company representative for details.

Handle with care. Before and during use, observe the safety labels on the packaging and paint containers and comply with all local and national safety regulations. Consult the Hempel Safety Data Sheet and Product Data Sheet for the product at all times.

For professional use only.

Surface Preparation

Cleanliness

• Remove oil, grease and other contaminants by cleaning with a suitable cleaner.

• Remove salts, detergents and other contaminants by high-pressure fresh water washing.

• Remove dust, blast abrasives and loose material by vacuum cleaning.

- Use high-pressure fresh water washing (approx. 30 MPa [4400 psi]) combined with scrubbing to remove zinc salt deposits and white rust.

- Before final painting, all shop primer breakdown and contamination incurred during storage and erection must be thoroughly cleaned by mechanical/chemical means.

New construction

• Abrasive blast clean to Sa 2½ (ISO 8501-1) / SP 10 (SSPC) minimum.

• Remove dust, blast abrasives and loose material.

Maintenance and repair

• Remove dust, blast abrasives and loose material.

1534C

Roughness

- Before recoating, roughen uncoated surfaces so that the appearance is uniform and dull, without blank spots.

• Small areas may be ground to obtain a uniform surface profile.

• For further details, refer to the separate Hempel document Surface Preparation Guide.

Application

Mixing Ratio

Base 1534R : Hardener 9574C (4 : 1 by volume)

Products containing floating or settling particles/pigments require continuous stirring during application; this is especially important when heavily thinned.

Pot Life

Recommended method

Nozzle pressure: 15 MPa

Airless Spray

Nozzle size: 0.43–0.53 mm

If brush or roller application is used, several coats may be required to achieve the specified dry film thickness. Keep thinning to a minimum. At low temperatures, additional thinning may be required, resulting in lower film build and slower drying. Spray parameters are indicative and may be adjusted to suit site conditions. Pressure figures apply to the material at 20 °C. (*For other application methods, consult the company representative.)

Film thickness

Depending on the use and application area, the product can be specified at a film thickness different from that indicated. This will change the spreading rate, drying and curing time, and overcoating interval. Actual consumption factors may vary with application conditions, equipment and workmanship. Over-thickness must be strictly controlled; locally it must never exceed 50 µm [2.0 mils] DFT. On irregular surfaces, special attention is recommended to avoid overuse.

Application conditions

• During application and curing, the surface temperature must be above 10 °C [50 °F].

• During application, the product temperature must be above 15 °C [59 °F].

• The surface to be coated must be clean and dry, and its temperature must be at least 3 °C [5 °F] above the dew point to avoid condensation.

• Provide adequate ventilation during application and drying.

Relative humidity

• During application, the relative humidity must be below 85%.

• During curing, the relative humidity must be below 85%.

Notes

- If brush or roller application is used, more coats are required to achieve the specified dry film thickness.

• This product requires heavy-duty spray equipment; hoses should be as short as possible.

• The practical consumption factor may vary with application conditions, equipment and workmanship.

• Checking paint consumption against area improves film thickness control.

• To avoid contamination of other areas, masking is recommended.

Drying and recoat

Drying Time

1534C

Recoat

Hempel's specifications supersede all guidance shown in the recoat table.

For products of the same generic chemical composition, recoat times are for reference only.

For further information, refer to Hempel's specifications.

Drying conditions

- To achieve the stated drying times, adequate ventilation during application, drying and curing is essential.

• Avoid condensation on the freshly applied coating.

Recoat notes

• If the maximum recoat interval is exceeded, the surface must be roughened to ensure intercoat adhesion.

• The recoat interval may be adjusted according to line speed, ventilation, environment and oven temperature.

• The surface must be clean before recoating.

• Before recoating, remove any exudate from the surface.

• Before recoating, remove zinc salts or other contaminants.

Others

• Epoxy coatings have an inherent tendency to chalk when exposed outdoors. This does not affect coating performance.

• Hempel's specifications supersede any recommendations in the Product Data Sheet.

Storage

Shelf Life

When stored in unopened original containers, shelf life is counted from the date of production. Thereafter, the product quality must be re-inspected. Storage at high temperatures may shorten the shelf life. For advice, consult Hempel.

Storage conditions

• Store under dry conditions. Protect from moisture ingress.

- Store the product in accordance with the Safety Data Sheet, label and local regulations. Keep containers in a dry, cool, well-ventilated place away from heat and sources of ignition. Keep containers tightly closed. Handle with care.

Carbon footprint

Carbon footprint is based on a 1 µm dry film thickness formed over a surface area of 1 m².

The scope includes raw materials, transport to the Hempel factory, the Hempel production process, and any volatile organic compounds (VOC) emitted during and after use of the product.
