HOLDBRITE IMO

ALKALINE CLEANER FOR THE REMOVAL OF HEAVY DUTY RESIDUES

• Effective cleaning of heavy duty residues from cargo hold tanks, decks, bulkheads, etc.

• Heavy duty, water-based cleaner.

• Efficient, multipurpose cleaning.

• Highly concentrated: dilute for most cleaning needs.

• Comprises special detergents, surfactants, builders and corrosion inhibitors.

• Removes soot from Inert Gas Systems (IGS).

• Non-flammable.

• Suitable to use with hot or cold water high pressure equipment.

• IMO-approved.

 

DESCRIPTION

HOLDBRITE is specifically formulated for the effective removal of heavy duty residues and can be also applied by high pressure spraying equipment. HOLDBRITE is highly concentrated, comprising special detergents, surfactants, builders and corrosion inhibitors. HOLDBRITE can be quickly dissolved in water for removing lighter grease, oil, pet coke and dirt deposits. Compatible with most coated surfaces and dries leaving a good shine.

HOLDBRITE is water based, non flammable, biodegradable and IMO-approved. Only cleaners registered in Annex10 of IMO’s MEPC.2/Circular can be used and disposed of at sea for cargo tank cleaning, when the cargo residue slops are disposable at sea.

Please refer to “CHEMO CARGO HOLD CLEANING SOLUTIONS” Brochure, which summarizes the solutions that CHEMO offers for tackling a variety of contamination and deposit problems.

 

APPLICATION

HOLDBRITE XF can be used for cargo hold and tanks cleaning and refrigeration vessels, as well as soot removal from Inert Gas Systems and general cleaning. HOLDBRITE effectively removes greases, waxes, vegetable and animal oils, sludge, soot, carbon deposits, dirt and grime. Diluted, it removes lighter grease, oil, petcoke and dirt deposits.

When applied on vertical surfaces, add  FOAM BOOSTER. This increases the residential time, thus cleaning efficiency.

Suitable for epoxy, but not for zinc silicate coatings. In this case, use our IMO-approved SUPER RED PLUS.

USE AND DOSING

Instructions are based on experience and are meant only as a guide since circumstances for each tank cleaning operation vary. They are not intended to interfere with the judgment of the vessel’s responsible personnel.

Precleaning tanks with high pressure warm water is highly recommended since large deposits of oil or other residues in the tank must be removed to ensure an eff‑ective cleaning operation.

• General Cleaning

For general use, dilute HOLDBRITE appropriately, depending on the contamination, and use conventional cleaning methods, such as brushing, scrubbing or hand spraying.

• Removal of Soot from Inert Gas Systems (IGS)

Dilute from 5 to 20% of HOLDBRITE in fresh water. Spray the solution onto the surface, using high pressure cleaning equipment. When used with a hand sprayer, apply 1 litre of neat HOLDBRITE per 12 m2. Allow the product to act and then rinse off with fresh water before drying. Allow solution to penetrate soil for about 30 minutes and then wash off thoroughly with high pressure fresh water, heated up to 80oC. Always wash off before chemicals dry on the surface. Repeat the procedure, if contamination persists.

• Cargo Tank and cargo hold cleaning

HOLDBRITE is ideal for tank cleaning for most types of contamination. Suitable for epoxy, but not for zinc silicate coatings.The dosage rate for direct injection with tank washing machines is 1-20 litres per ton wash water (0.1-2.0%).

For recirculation, use a rate of 1-20 litres per ton wash water (0.1-2.0%). For heavily soiled areas, a preliminary cleaning is required. If surface is heavily contaminated, higher concentrations of the product in water can be used.

When used for spot cleaning, apply by hand spraying neat or prepare a 20% solution, and allow solution to penetrate soil for about 30 minutes before rinsing off with water. Always wash off before chemicals dry on the surface.

If HOLD BARRIER or HOLD BARRIER XR (Prod. Codes: 507001 & 507002) is applied to the cargo hold surfaces prior to loading, the concentration of HOLDBRITE in the cleaning solution may be reduced.

RECOMMENDATIONS

Safe to use on all metal surfaces and parts except aluminium, zinc, tin and its alloys. It is highly recommended to always test all cleaner solutions on a small area of tank coating, before full scale application.
