Features and Benefits

Surface tolerant
Recommended for painting over rusted steel where hand cleaning only is possible
Carbomastic 15 LT penetrates through rust to steel substrate and stops further corrosion and undercutting
Fast curing at low temperatures
High solids give good coverage and reduced solvent emission
Excellent maintenance primer for piping, bridges, tank exteriors, ships and offshore structures, etc

These times are based on recommended DFT. Higher film thickness, insufficient ventilation or cooler temperatures will require longer cure times and could result in solvent entrapment and premature failure

Surface Preparation

General

May be used over most generic types of coatings which are tightly adhering to the substrate including organic- and inorganic zinc primers

Steel

Preferably blasting however hand- or power tool cleaning is acceptable standard in many cases to remove non adhering paint and rust. Alternatively, ultra high pressure water jetting to Nace No. 7 min. C Vis WJ-2. Max flash rust; C Vis WJ-2M

Health and Safety

Clean Up

Use Thinner 2 or Thinner 25
In case of spillage, absorb and dispose of in accordance with local applicable regulations

Safety

Read and follow all caution statements on this product data sheet and on the safety data sheet for this product
Employ normal workmanlike safety precautions
Hypersensitive persons should wear protective clothing, gloves and use protective cream on face, hands, and all exposed areas

Ventilation

When used as a tank lining or in enclosed areas, thorough air circulation must be used during and after application until the coating is cured
The ventilation system should be capable of preventing the solvent vapor concentration from reaching the lower explosion limit for the solvents used

Caution

This product contains flammable solvents. Keep away from sparks and open flames
All electrical equipment and installations should be made and grounded in accordance with the applicable local regulations
In areas where explosion hazards exist, workmen should be required to use non-ferrous tools and wear conductive and non-sparking shoes
