Clear Epoxy Seal or Topcoat
abecote® 436 is a two-component solvent-borne, polyamine-cured epoxy coating.
Uses
abecote® 436 is a sealer for porous cementitious substrates.
abecote® 436 may also be used as a clear seal coat for abescreed.
Advantages
- Good sealing characteristics
- Easy to apply
- Non-toxic when cured

Do NOT apply | If humidity in excess of 85% |
Do NOT apply | If surface is less than 2°C above dew point. |
Surface Preparation
Cementitious substrates only:
The substrate must be dry before application 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 hours
or
(a practical overnight “plastic sheet test” is also advisable approx. 1m2 masked down on surface).
Bonding / Priming
Not required.
Mixing
Stir the contents of each container. Add activator to base and stir together for at least five 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 rpm) fitted with a paddle.
The mixed material must be left to stand for 20 minutes prior to application.
If only part of a kit is to be used add one volume of activator to 4 volumes of base. Measuring must be accurate and separate stirrers and containers used for proportioning each component.
Application
abecote® 436 may be applied by brush, short-fibre roller or airless spray. Spraying would be through a tip of approximately 250 μm. abecote® 436 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 2°C above the dew point a film of condensed moisture may be present. This will undermine adhesion of the coating.
Provide adequate ventilation during application and ensure that there are no sources of ignition in the vicinity.
Coverage
10 to 12 m2/L (smooth surfaces).
Cleaning of Equipment
abe® super brush cleaner before setting.
Protection / Maintenance on Completion
Protect surface against traffic and spillage until cured. Most epoxies chalk and degrade in extensive sunlight.
Model Specification
Two-component solvent based epoxy resin floor coating. The coating will be abecote® 436; a two-component epoxy resin coating system applied in accordance with a.b.e.® recommendations.
Packaging
abecote® 436 is supplied in 1L and 5L yield metal containers.
Handling & Storage
All abecote® 436 related products have a shelf life 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 shelf life may be reduced.
Health & Safety
Product safety information required for safe use is not included. Before handling, read product and safety data sheets and container labels for safe use, physical and health hazard information. The safety data sheet is available from your local a.b.e.® sales representative.
