What makes Barrier Smart Pack different?

NORSOK compliant on ST3 prepared steel Designed to achieve typical DFT in one coat by brush and roller

BARRIER SMART PACK

Surface tolerant ceramically reinforced zinc epoxy primer High volume solids (70%) Low VOC 300 g/L 1:1 mixing ratio for reduced mixing errors and waste

Surface tolerance

• Unique combination of binders and hardener
• Worlds first surface tolerant for a zinc rich epoxy with external

documentation (NORSOK)

• Lower molecular weight epoxy and hardner gives better

penetration into the steel substrate

− More mobility of the molecules − Better surface tolerance − Require less roughness

Superior corrosion resistance

Barrier Smart Pack 70 mm Std 80% zink epoxy 40 mm

• Optimized combination of

binders, hardener and additives improves availability of zinc particles to act as cathodic protection

• High zinc dust level of 80%
• Gives the required DFT according

to standards, in one coat and delivers a even film

Brush application 6 months salt spray

Superior corrosion resistance

• Ceramic spheres adds volume inaccessable to zinc dust
• Compresses zinc dust into a much smaller volume increasing contact point between

the zinc particles and the steel

− More activated zinc / more available zinc to protect

Mixing of components

• 1:1 mixing ratio by volume
• Robust against wrong ratios +/- 15%
• Visual indicator for proper mixing

− Easy indication as soon as all the white has disappeared

Application by brush&roller

• Coating rheology goes «hand-in-hand» with design of

application equipment

• Barrier Smart Pack has an unique thixotropic

− Slow recovery thixotropic agents provides ample anti- settling properties and excellent flow and leveling − Low viscosity while applying gives little resistance for the applicator − In cobination with high body gives the proper film thickness «in one go»

Brush application

• Robust to application equipment
• Designed to give best application when

applied by low cost/low quality brushes with relatively high stiffeness

• Soft synthetic brushes will give

improved finish and more even DFT

• We recommend:

− A long haired soft synthetic or semi- synthetic brush to give the best flow and appearance.

Roller application

• Different rollers – different appearence

and DFT

• Barrier Smart Pack is very robust to

roller type

− All rollers tested gives minimum 60mm DFT

• We recommend:

− Short haired filt roller (picture) of high quality

Spray application

Barrier Smart Pack has excellent sprayability with airless, HVLP and conventional spray

Battery driven airless

Reduced wrong mixing and waste

Easy 1:1 mixing ratio – Reduces wrong mixing or mixing to much for the job Visual instructions on lids - No mix up of components Less mistakes and less paint thrown away
