Epoxy Enamel Coating

abe.®cote 320 is a two component, solvent borne, pigmented polyamide cured epoxy coating.

Uses

abe.®cote 320 is a decorative and protective coating for most surfaces not exposed to extensive sunlight.

Advantages
  • abe.®cote 320 provides an economical hard finish, which offers surfaces improved abrasion resistance and aesthetic finish
  • Suitable for walls and containment areas free of extensive sunlight. Excellent for resistance to sugar, solvents, salt spray and several chemicals

Surface Preparation

Steel shall be grit blasted to a minimum standard of Sa 2 ½ on the Swedish Code of Practice SIS 055900. The prepared surface must be free of all corrosion deposits and contaminants and provide a water break free surface.

Concrete shall be free of all laitance and preferably should be lightly vacuum blast cleaned. The prepared surface must be dry, clean, sound and free of all contaminants and friable matter. All blemishes in the surface such as pop-outs, omegas, blowholes and honeycomb should be patched with epidermix 318. This should be left overnight to cure and shall then be rendered smooth.

Bonding/priming

abe.®cote 320 is normally only applied over previously primed and undercoated surfaces. Metals would normally be primed with abe.®cote 384, and porous surfaces with abe.®cote 386. Any contamination on a primed surface must be removed before applying abe.®cote 320. A wash down with abe.®cote thinners no. 3 will probably be sufficient. If optimum appearance is desired, the primer film should be overcoated with abe.®cote 386 and when dry, this should be sanded down to achieve a smooth base. Any debris of preparation must be removed before coating commences.

Mixing

Stir the contents of each container, particularly the base, very well. Add activator to base and stir together for at least 5 minutes using a flat paddle. It has been found that mechanical mixing gives better dispersion than manual mixing. A suitable mixing method would be a slow speed electric drill (approximately 200 r/min) fitted with a paddle. If only part of a kit is to be used,add one volume of activator to two volumes of base. Measuring must be accurate and separate stirrers and containers used for proportioning each component. The mixed material must be left to stand in a cool place for 20 minutes prior to application.

Beware of high summer temperature and overfast mixing causing extremely fast curing. Very low winter temperatures retard/stop curing.

  1. In order to avoid colour variation in large expanses one must ensure that the same batch is used, since slight color variation from batch to batch is unavoidable (factory batching available on request).
  2. The substrate must be dry before application. For concrete, moisture content tests must be conducted prior to application of the priming system. Testing for moisture (e.g. protimeter survey master or equivalent), or dynamic calcium chloride moisture “weight gain” over 24 hours, or a practical overnight “plastic sheet test” is also advisable approximately 1m2; masked down on surface. Concrete substrate must have a minimum tensile adhesive strength of 1.5 N/mm2.
  3. Concrete substrate must have a minimum tensile adhesive strength of 1.5 N/mm2.
  4. Prevailing weather conditions must be taken into account otherwise surface defects can occur (see under “properties of wet material”).

abe.®cote 320 may be applied by brush, short fiber roller or airless spray. Spraying would be through a tip of approximately 250 μm. Stir frequently during use.

abe.®cote 320 should not be applied if the ambient temperature is below 10 °C .The curing reaction will not proceed at low temperature. If surfaces are not at least 3 °C above the dew point, there is every chance that a film of condensed moisture may be present. This will upset adhesion of the coating. Wet film thickness should not exceed the recommended figures as solvent entrapment could result. The same condition may be caused if overcoating times are shortened. Solvent entrapment in the film can lead to poor performance.

Cleaning

abe® super brush cleaner before setting.

Protection On Completion

Protect the surface against traffic and spillage until cured.
Most epoxies chalk and degrade in extensive sunlight.

Model Specification

Two component solvent borne epoxy enamel coating.

The coating will be abe.®cote 320, a two component solvent borne epoxy enamel coating applied in accordance with a.b.e.® Construction Chemicals’ recommendations, including necessary primers as directed.

Packaging

abe.®cote 320 is supplied in 5 L yield metal containers.

Handling And Storage

All abe.®cote 320 related products have a shelflife of 12 months if kept in a dry, cool store in the original, unopened packs.

If stored at high temperatures and/or high humidity conditions, the shelflife may be reduced.

Health And Safety

Wet abe.®cote 320 is toxic and flammable. Always ventilate a working area very well during application and drying. Avoid naked flames in the vicinity.

Avoid inhalation of fumes/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.

Cured abe.®cote 320 is inert and harmless. Separate material safety data for base and activator is available on request.
