Product Characteristics

Description

Hempel Silicone Heat-resistant Paint 601 569CN is a heat-resistant silicone coating that cures under atmospheric conditions to form a hard film.

Recommended use

Can be used as a long-term protective coating for hot pipes, exhaust pipes, chimneys and other hot surfaces. Available in 10 colours. In corrosive environments, a previous coat of primer is required.

Service temperature

• Under dry conditions: maximum service temperature 600 °C [1112 °F].

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

- The maximum permitted water-soluble salt level tested in accordance with ISO 8502-9 is 50 mg/m² (as NaCl).

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

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

New construction

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

• In accordance with Hempel's specifications.

Roughness

• Surface roughness Coarse (G) (ISO 8503-2).

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

Application

Mixing Ratio

Base 569C9 : Curing agent 960CN (22.5 : 1 by volume)

Stir thoroughly before use.

Pot Life

Recommended method

If brush or roller application is used, multiple coats are required to achieve the specified dry film thickness. Additional thinning may be required to reduce dry spray at high temperatures. Do not thin components separately — thinning may be carried out after mixing. Keep thinning to a minimum. Additional thinning may be required at low paint temperatures, which will result in lower film thickness and slower drying. Spray parameters are indicative and may be adjusted according to site conditions. Pressure values apply to the material at 20 °C. (*Consult a company representative if other application methods are required!).

Film thickness

To achieve optimum performance, avoid excessive film thickness. Depending on the end use and service area, the product may be specified at film thicknesses other than those indicated. This will alter the spreading rate, drying and curing times and recoat interval. The practical consumption factor may vary with application conditions, equipment and workmanship. Checking paint consumption against area improves film thickness control.

Application conditions

• 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.

• During application and curing, the surface temperature must be above 5 °C [41 °F].

Relative humidity

• During curing, the relative humidity must be within the range of 50–100%.

Notes

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

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

• Checking paint consumption against area improves film thickness control.

• Stir thoroughly before use.

• Do not open or mix the paint containers before use.

Drying and recoat

Product compatibility

• Previous coat: according to Hempel's specifications.

• Subsequent coat: according to Hempel's specifications.

Drying Time

Dry film thickness measured under standard conditions at 30 µm; see Hempel's explanatory notes for details. To determine the dry state, refer to Application Specification COP FP1401-1 (drying test for high film thickness).

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 surface must be clean before recoating.

Others

• 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.
