PRODUCT CHARACTERISTICS

Recommended use

Hempadur Quattro 17634 is recommended as a universal, self-primed, high performance coating for atmospheric or immersion service, including cargo holds, water ballast tanks and cargo oil tanks to be coated according to IMO-PSPC requirements. It is intended for all year application and for in-shop applications where fast recoating and handling is required. It is also recommended for long time corrosion protection of structural steel and concrete in severe corrosive and immersed environments. The product resists normal ambient temperatures at sea when used in ballast water service (avoid long-term exposure to negative temperature gradients). For resistance to other liquids, please contact Hempel.

Service temperature

• Maximum, dry exposure only: 120°C [248°F].
• Other liquids: Please contact Hempel.
• Avoid long-term exposure to negative temperature gradients.

Certificates / Approvals

• EC-type examined as a low flame spread material when used as part of a predefined paint system. Please refer to “Declaration of Conformity” on hempel.com for further details.
• This product is type approved according to PSPC requirements based on crossover testing over a wide range of shopprimers. Consult Hempel for specific Type Approval Certificates as defined in IMO Resolution: MSC.215(82), MSC.288(87).
• Complies with US FDA and EU food regulations for contact with dry foodstuff. Consult Hempel for details.

Features

Overcoating times are indicative for products of the same generic chemistry. Consult Hempel’s specification for more information.

Drying conditions

• To obtain the drying time stated, it is important to maintain sufficient ventilation during application, drying and curing.

Overcoating details

• If the maximum overcoating interval is exceeded, roughening of the surface is necessary to ensure intercoat adhesion.
• The surface must be dry and clean prior to application.

Other remarks

• Epoxy coats have an inherent tendency of chalking in outdoor exposure. This does not affect the performance of the coating.
• Hempel’s Specification supersedes any recommendations given in the Product Data Sheets.
