Hostagrund U2161 Rust Blocker Primer for Metal, 2.5 l

The Hostagrund Rust Blocker U2161 is a single-component polyurethane primer paint that cures by atmospheric humidity.

CHARACTERISTICS AND USE:

The paint is intended for primer applications on metals, ensuring adhesion of subsequent coating systems on problematic surfaces (steel surfaces with residual corrosion, light and colored metals), such as underground collectors, metal tanks, pipes, machinery, operational structures, roofing, and bridge structures. It is especially effective when applied in humid environments where other coatings fail. It is also suitable for priming porous and weakly cohesive absorbent substrates. The cured coating has excellent chemical resistance. It is permanently resistant to seawater and gasoline.

Key properties

• Applicable in humid environment
• High adhesion even on surfaces with residual corrosion
• Blocks further corrosion
• Transparent coating

SUBSTRATE PREPARATION:

The substrate must be clean, dry, free of grease and loose rust, and mechanically cleaned. Previously painted surfaces must be cleaned, degreased, and stripped of old non-adhering coatings. To ensure compatibility of the new coating with the old, it is recommended to contact the manufacturer or perform a test patch on an area of 1 m².

DILUTION: thinner BALTECH S6005 (for cleaning tools). Application by brush and airless spraying does not require dilution.

Theoretical coverage: 15 – 21.5 m2/1 liter in one layer

APPLICATION PROCEDURE:

1.) 1-2 coats of Hostagrund paint, ensuring that the total resulting thickness of the dry coating film does not exceed 10 µm. The second layer may be applied within 2 – 3 hours of drying (20 °C / 50 – 98% relative humidity). When priming absorbent substrates, the second layer can be applied immediately after absorption. Before applying additional coatings, a technological break of approximately 2 up to a maximum of 24 hours is necessary depending on application conditions (the lower the layer of the coating film and the higher the temperature and relative humidity, the faster curing and shorter necessary technological break).
2.) 1-2 coats of primer S 2003 FORMEX PRIMER FOR GALVANIZED in a coating film thickness of 40 – 80 µm.
3.) 1-2 coats of enamel U 2029 INDUSTROL PROFI in a coating film thickness of 40 – 80 µm.

Warning:

Protective gloves are an integral part of the product. Individuals with heightened sensitivity to diisocyanates may experience allergic reactions when using this product. Persons suffering from asthma, eczema, or skin problems should avoid contact with this product, including dermal contact. In conditions where adequate ventilation is not ensured, this product should not be used without protective mask with a suitable gas filter (i.e., type A1 according to EN 14387).

As of August 24, 2023, appropriate professional training is required for industrial or professional use.

It is recommended to consume the entire package in one use, as opening the packaging may lead to a reaction of the liquid paint with air humidity, resulting in degradation of the entire contents.
