Epoxy Enamel Coating
abecote® 320 is a two component, solvent borne, pigmented polyamide cured epoxy coating.
- abecote® 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
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.

abecote® 320 is normally only applied over previously primed and undercoated surfaces. Metals would normally be primed with abecote® 384, and porous surfaces with abecote® 386. Any contamination on a primed surface must be removed before applying abecote® 320. A wash down with abecote® thinners no. 3 will probably be sufficient. If optimum appearance is desired, the primer film should be overcoated with abecote® 386 and when dry, this should be sanded down to achieve a smooth base. Any debris of preparation must be removed before coating commences.
Beware of high summer temperature and overfast mixing causing extremely fast curing. Very low winter temperatures retard/stop curing.

- 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).
- 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.
- Concrete substrate must have a minimum tensile adhesive strength of 1.5 N/mm2.
- Prevailing weather conditions must be taken into account otherwise surface defects can occur (see under “properties of wet material”).
abecote® 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.
abecote® 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.

Protection On Completion
Protect the surface against traffic and spillage until cured.
Most epoxies chalk and degrade in extensive sunlight.
The coating will be abecote® 320, a two component solvent borne epoxy enamel coating applied in accordance with a.b.e.®’s recommendations, including necessary primers as directed.
abecote® 320 is supplied in 5 L yield metal containers.
Handling And Storage
All abecote® 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 abecote® 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 abecote® 320 is inert and harmless. Separate material safety data for base and activator is available on request.
Where other products are to be used in conjunction with this material, the relevant technical data sheets should be consulted to determine total requirements. a.b.e.® has a wealth of technical and practical experience built up over years in the company’s pursuit of excellence in flooring and concrete technology.
