Product Details

Drying Times

• Stated figures for pot life, drying times and overcoating intervals are for temperate product

Surface Preparation

• Use in accordance with the standard Worldwide Marine Specifications
• All surfaces to be coated should be clean, dry, and free from contamination
• High pressure freshwater wash or freshwater wash, as appropriate, and remove all oil or grease, soluble contaminants, and other foreign matter in accordance with SSPC-SP1 solvent cleaning

Application Conditions

Major Refurbishments

• Abrasive blast clean to Sa2 (ISO 8501-1:2007). If oxidation has occurred between blasting and application of Interbond 201, the surface should be reblasted to the specified visual standard. Surface defects revealed by the blast cleaning process, should be ground, filled, or treated in the appropriate manner
• Interbond 201 may be applied to surfaces prepared to International Paint Hydroblasting Standard HB2 which have flash rusted to no worse than HB2M. Hydroblasting is only recommended for cargo holds, topsides and above water areas.
• Or - Interbond 201 may be applied to surfaces prepared to International Paint Slurry Blasting Standard SB2 where flash rust is no worse than SB2M. Slurry blasting is only recommended for topsides and above water areas.

Repair/OBM - Exposed Steel and Corrosion

• Hand or power tool clean to a minimum St2 (ISO 8501-1:2007).Note, all scale must be removed and areas which cannot be prepared adequately by chipping or needle gun should be spot blasted to a minimum standard of Sa2 (ISO 8501-1:2007). Typically, this would apply to C or D grade steel in this standard
• Or - Abrasive blast clean to Sa2 (ISO 8501-1:2007). If oxidation has occurred between blasting and application of Interbond 201, the surface should be reblasted to the specified visual standard
• Surface defects revealed by the blast cleaning process, should be ground, filled, or treated in the appropriate manner
• Or - Interbond 201 may be applied to surfaces prepared to International Paint Hydroblasting Standard HB2 which have flash rusted to no worse than HB2M
• Or - Interbond 201 may be applied to surfaces prepared to International Paint Slurry Blasting Standard SB2 where flash rust is no worse than SB2M
• Interbond 201 is suitable for overlap onto most aged coating systems. Loose or flaking coatings should be removed back to a firm edge and Interbond 201 should be applied to overlap the existing coating by 2-3 centimetres (one inch). Glossy epoxies and polyurethanes may require abrasion

Intact Coatings

• This product may be applied as a full coat over most generic types of paint that have been aged for at least 3 months. It is advisable that a small trial be carried out before applying a full coat over certain generic types
• Contact Rawlins Technical Team on 0113 2455450 (option 2) or [email protected] for acceptable generic types and extent of surface preparation required
• Accurate film thickness control is essential, particularly when overcoating existing systems

Wet Holds

• Abrasive blast clean to Sa2½ (ISO 8501-1:2007)
• or - Interbond 201 may be applied to surfaces prepared to International Paint Hydroblasting Standard HB2½ which have flash rusted to no worse than HB2½L

Noteson Overcoating at Repair/OBM

• Interthane 990 may be applied to weathered (chalked) temperate Interbond 201 more than 3 months old, provided that the surface is treated by fresh water washing to remove all dirt and contamination followed by degreasing according to SSPC-SP1 solvent cleaning
• Interthane 990 should not be used to overcoat Interbond 201 low temperature
• For good cosmetics Interbond 201 low temperature should be overcoated with Intergard 740 or Intersheen 579

Application

Mixing

Material is supplied in 2 containers as a unit. Always mix a complete unit in the proportions supplied.

• Agitate Base (Part A) with a power agitator
• Combine entire contents of Curing Agent (Part B) with Base (Part A) and mix thoroughly with power agitator

Mix Ratio

• 4.00 volume(s) Part A to 1 volume(s) Part B

Thinner

• International GTA220. Thinning is not normally required
• Contact Rawlins Technical Team on 0113 2455450 (option 2) or [email protected] for advice during application in extreme conditions
• Do not thin more than allowed by local environmental legislation

Airless Spray

• Recommended Tip Range 0.53-0.84 mm (21-33 thou)
• Total output fluid pressure at spray tip not less than 176 - 246 kg/cm² (2500 - 3500 p.s.i.)

Conventional Spray

• Application by conventional spray is not recommended

Brush

• Application by brush is recommended for small areas only
• Multiple coats may be required to achieve specified film thickness

Roller

• Recommended

Cleaner

• International GTA220/GTA822

Work Stoppages and Clean-up

• Do not allow material to remain in hoses, gun, or spray equipment
• Thoroughly flush all equipment with International GTA220/GTA822
• Once units of paint have been mixed, they should not be resealed, and it is advised that after prolonged stoppages work recommences with freshly mixed units
• Clean all equipment immediately after use with International GTA220/GTA822
• It is good working practice to periodically flush out spray equipment during the working day
• Frequency of cleaning will depend upon amount sprayed, temperature and elapsed time, including any delays
• Do not exceed pot life limitations
• All surplus materials and empty containers should be disposed of in accordance with appropriate regional regulations/legislation

Welding

• In the event welding or flame cutting is performed on metal coated with this product, dust and fumes will be emitted which will require the use of appropriate personal protective equipment and adequate local exhaust ventilation
• In North America do so in accordance with instruction in ANSI/ASC Z49.1 "Safety in Welding and Cutting."

Limitations

• When spraying large areas, application of a brush coat is recommended over pitted or rough surfaces to ensure full penetration
• Stripe coating of complex structures is recommended
• Interbond 201 low temperature grade is not suitable for use in Ballast Holds
• Optimum performance is achieved when Interbond 201 is applied over blasted steel
• In common with all epoxy-based coatings Interbond 201 will exhibit chalking of the film on UV exposure
• Overcoating information is given for guidance only and is subject to regional variation depending upon local climate and environmental conditions
• Contact Rawlins Technical Team on 0113 2455450 (option 2) or [email protected] for specific recommendations
• Apply in good weather. Temperature of the surface to be coated must be at least 3°C above the dew point
• For optimum application properties bring the material to 21-27°C, unless specifically instructed otherwise, prior to mixing and application
• Unmixed material (in closed containers) should be maintained in protected storage in accordance with information given in the STORAGE Section of this data sheet
• Technical and application data herein is for the purpose of establishing a general guideline of the coating application procedures 
• Test performance results were obtained in a controlled laboratory environment and International Paint makes no claim that the exhibited published test results, or any other tests, accurately represent results found in all field environments
• As application, environmental and design factors can vary significantly, due care should be exercised in the selection, verification of performance and use of the coating
