abecote® SF 356 epoxy tar coating and binder

Black finish.

Any surface must be clean, mechanically sound and dry.

For porous surfaces, electronic moisture content tests must be conducted prior to application of the priming system. Maximum moisture 4-5% max. (e.g. Protimeter Survey Master or equivalent)

or

Dynamic Calcium Chloride moisture “weight gain” over 24 hrs

or

a practical overnight “plastic sheet test” is also advisable approx. 1m² masked down on surface).

Steel – Surfaces must be free of all rust and millscale. They should be abrasive blasted to a minimum standard of Sa 2,5 of Swedish Code of Practice SIS 055900. If immersion service is contemplated then a standard of Sa 3 should be attained.

Anchor pattern must never exceed 100 μm and preferably should be in the 50 – 75 μm range.

Galvanised Steel – Galvanised steel must be completely free of any trace of greasy matter and should be scrubbed with abrasive pad or proprietary abrasive cleaner until completely ‘nongreasy’.

The cleaned surface must be well washed with clean water and allowed to dry.

Concrete – Concrete must be free of laitance, curing membranes and shutter release oil. All blow-holes, omegas and other similar defects must be opened and the best method of preparation is a light abrasive blast. If a smooth surface is desired, any major surface blemishes should be patched and smoothed with epidermix® 201, with overcoating following within 48 hours.

Timber – Timber must be free of any oily layers and should be reasonably smooth.

Asphalt – Surfaces to be new and free of contamination. Existing asphalt surfaces must be well scrubbed with abe^® super brush cleaner and then washed with clean water to remove all residues. The asphalt must be completely dry before coating and on no account must diluted abecote^® SF 356 be used.

All debris of preparation must be removed before any coating commences.

Steel must be primed with abecote^® 384.

Galvanised steel and zinc coatings – abecote^® SF 356 must never be applied directly to these surfaces – use abecote^® 386 as a barrier coat. Concrete, masonry and timber must be primed with abecote^® SF 356 diluted 1:1 with abe^® thinners no. 3. This coat must be allowed to dry before overcoating proceeds. Fresh concrete must be primed with abecote^® 337 and cured for 72 hours before overcoating. Asphalt must be primed with undiluted abecote^® SF 356.

abecote^® SF 356 coating

Stir the contents of each container very well. Add the activator to base and stir together for at least 5 minutes using a flat paddle. If only part of a kit is to be used, add one volume activator to one volume base. Measuring must be accurate and separate stirrers and containers used for proportioning each component. abecote^® SF 356 is designed as a solvent-free material. If it is being used on concrete, timber or masonry the first coat should be diluted with abe^® thinners no. 3. Up to 50% may be added, producing a primer of 50% volume solids. This should be applied at about 6 m²/ℓ.

abecote^® SF 356 mortar

Clean, dry, dust free silica sand may be mixed into abecote^® SF 356 to make a screeding mortar. It is normal to add three volumes of silica to one of mixed abecote^® SF 356. This is mixed thoroughly in a rotating pan type mixer until the aggregate is fully coated.

abecote^® SF 356 coating

abecote^® SF 356 should be applied by brush or short-fiber roller. When applying over asphalt a rubber squeegee may be used.

To improve traction it is common practice to blend the still wet abecote^® SF 356 with dry, dust-free sand or fine chippings.

Being an amine-cured system abecote^® SF 356 is prone to ‘bloom’ if drying occurs when humidity is high. This results in a haze forming on the surface of the coating, which is detrimental to good intercoat adhesion. If ‘bloom’ is present the surface must be wiped down with abe^® thinners no. 3 before recoating.

Semi-confined areas – although solvent-free, amine fumes require that breathing apparatus be used and that working areas be well ventilated.

abecote^® SF 356 MORTAR

The usual thickness of this mortar is 5 mm and it must be laid on to a surface which has previously been primed with a diluted coat of abecote® SF 356 as detailed under PRIMING of concrete and masonry above.

Mortar yields 2ℓ kit+13 kg sand yields approx. 6.9ℓ 5ℓ kit + 3×9.5 kg sand yields approx. 15.7ℓ

abecote^® SF 356 should not be applied if the ambient temperature is below 10 °C. The curing reaction will not proceed at low temperatures.

If surfaces are not at least 2 °C above the dew point, a film of condensed moisture may be present. This will adversely effect adhesion of the coating. When work is carried out in full sun, the surface temperatures may rise far above ambient, it will be found that the film will remain thermoplastic until full cross-linking of the coating has taken place.

abe^® super brush cleaner before dried/cured.

Protect surface against traffic and spillage until cured.

Two-component, solvent free, high chemical resistant amine cured epoxy coal tar system. The coating/flooring will be abecote^® SF 356, a two component, solvent free, high chemical resistant amine cured epoxy coal tar applied in accordance with a.b.e.^® recommendations including necessary primers and fillers where directed.

abecote^® SF 356 is supplied in 2ℓ and 5ℓ metal containers.

All abecote® SF 356 rrelated products have a shelf life of 24 months if kept in a dry, cool store in the original, unopened packs. If stored at high temperatures and/or high humidity conditions, the shelf life may be reduced.

Uncured abecote^® SF 356 is toxic. Ensure working area is well ventilated during application and drying.

Avoid inhalation of dust and contact with skin and eyes. Suitable protective clothing, gloves, eye protection and respiratory protective equipment should be worn. The use of barrier creams provides additional skin protection. If contact with skin occurs, wash with water and soap. Splashes into eyes should be washed immediately with plenty of clean water and medical advice sought.
