SAND-ABLE EPOXY UNDERCOAT

EASY FAIR SEU, sand-able epoxy undercoat is a two component high build epoxy coating that is easy to sand to a smooth finish. It is a moderately hard coating that has been developed to fill surface defects in existing coatings such as orange peel, brush marks or roller stipple. It is an essential product if a perfectly smooth finish is required before the application of finishing coats.

• Waterproof pure epoxy, designed for application over osmosis protection coatings
• Easy to apply in thick coats with a medium pile roller.
• Efficiently fills orange peel and imperfections
• Contains specially selected soft fillers - easy to sand to a smooth finish

EASY FAIR SEU should be applied with a roller or a brush. Its primary use is for application over SAFEGUARD TSF or EA osmosis treatment coatings where a perfectly smooth surface is required for the application of antifouling.

PREPARATION. The substrate must be clean, dry and free of grease or other contamination. If the surface is smooth or glossy abrade to a mat finish to provide a key.

MIXING  Epoxy resins and hardeners must be thoroughly mixed in the correct ratios to ensure complete curing of the product. Each can of REACTIVE RESINS coatings is supplied with the correct amount of hardener, all of which must be added to the can of resin and mixed well immediately before use. Do not try to accelerate or retard setting of the material by varying the amount of hardener used as this will cause the coating not to set at all, or to prematurely fail. Thorough mixing is also critical to the correct curing of the product and although small packs can easily be mixed by hand, a spiral mixer used in a pneumatic or cordless drill is essential for mixing larger packs. The pot life that is stated in each products literature will depend on the ambient temperature. Pot life can be extended by pouring the mixed material into trays which will allow the exothermic heat generated by the curing reaction of the resin and hardener to dissipate. Do not mix more material than can be used within its pot life. If a smaller amount is required than is in a pack, the components must me accurately weighed in the proportions shown on the product label. Digital kitchen scales are ideal for this purpose and are much easier to use than the spring type. Simply tare off the scale, pour out an approximate amount of resin, calculate the amount of hardener required, tare off the scales again and accurately weigh out the hardener. Proportioning by eye or by volume is not sufficiently accurate to achieve reliable results.

APPLICATION EASY FAIR SEU is best applied by brush or roller. If applying by spray the gun must be held at 90o to the surface to avoid build up on high spots. It should be applied within the previous coatings over-coating period or it should be abraded to provide a key. Pot life is 4 to 6 hours depending on the ambient temperature. Up to 5% SYNSOL 100 solvent may be added in cold weather or for spray application.
