EPOXY R
DESCRIPTION:
E-Poxy R is a solvent-free, 100% solids, high build epoxy resin coating. The formulation allows the incorporation of anti-slip grits and provides good chemical and abrasion resistance. E-Poxy R is available in a range of colours* by adding colour packs. An on-site trial should be carried out to ensure that the correct grade of grit is chosen so that the required degree of slip resistance and aesthetic appearance is obtained. Consult Adcrete Industries Pty Ltd when alternative specialized grits are required.
USES:
A heavy duty, industrial/commercial surface treatment for concrete floors and walls that is attractive and easily cleaned. Highly resistant to chemical attack and the action of forklift vehicular and commercial type traffic. When used in conjunction with the appropriate slip resistant medium. E-Poxy R is suitable for use in wet areas where strict levels of hygiene and cleanliness are required or where chemicals are manufactured, spilled or are an integral part of the process. Used in the food and chemical industry, hospitals, schools, kitchens, high traffic applications and many other installations. Specifically selected and processed grades of quartz sand anti-slip grits are available to make safe all types of working areas for both personnel and plant. E-Poxy R may be used without anti-slip grit as a sealer on concrete floors, epoxy floor screeds or as a high quality protective coating for walls, coves, drains, etc and is readily available in a range of colours.
FEATURES/BENEFITS:
• Long lasting and easily maintained with good resistance to many industrial chemicals. • Slip resistance improves safety for plant and personnel. • Certified ‘non-taint’ around food stuffs during and after installation. • Provides an attractive satin finish. * NB: Care has been taken to ensure that colours are as close as possible to agreed reference samples. However, it should be noted that no guarantee can be given of exact colour matching.

To extend pot life pour the product into flat trays such as roller trays.
CHEMICAL PROPERTIES:
E-Poxy R is resistant to a wide range of chemicals. Resistance to spillages (examples only) ♦ Toluene ♦ Sulphuric Acid 30% ♦ Acetic Acid 5% ♦ Sodium Hydroxide 30% ♦ Sodium Chloride ♦ Ammonia 20% ♦ Kerosene ♦ Used sump oil ♦ Petrol ♦ Hydrochloric acid ♦ Lactic Acid 5% ♦ Vegetable oils Surface staining may result from exposure to some aggressive chemicals. Good housekeeping practice requires spills to be quickly removed and washed.
MAINTENANCE:
The service life of a floor can be considerably extended by good housekeeping practices. Regular cleaning of E-Poxy R may be carried out using a rotary scrubbing machine with a water miscible cleaning agent.
APPLICATION INSTRUCTIONS:
Surface Preparation: It is essential that E-Poxy R is applied to sound, clean, dry substrate in order to achieve maximum adhesion between the floor coating and substrate. Because E-Poxy R is a relatively thin coating, the substrate must be fine textured. Any surface irregularities may show through causing excessive wear on high spots. If surface preparation produces an excessively deep profile on the substrate, advice should be sought from Adcrete Industries Pty Ltd regarding suitable methods to produce a smooth and level substrate. A ‘scratch coat’ of E-Poxy Binder and fillers is often used to smooth out irregularities. Steel should be grit-blasted to remove all scale, rust, grease, etc.
Priming: On very porous concrete an additional (3rd) coat of E-Poxy R may be required or the area may need to be primed with E-Poxy Binder. New Concrete Floors: Unless water-reduced, the floor should be at least 28 days old and give a hygrometer reading not exceeding 80% AH. Dry removal of laitance by light grit-blasting is preferable but, where this is not feasible, treat with an acid wash, followed by thorough neutralizing and rinsing with water and complete drying. Dust and other debris should then be removed by vacuum brush. Old Concrete Floors: A sound, clean substrate is essential to achieve maximum adhesion. Light grit blasting or acid etching should be carried out as for new concrete floors. Depending on extent of the contamination, oil and grease penetration may be removed by hot compressed air treatment and primed with E-Poxy Binder. Adhesion tests must be carried out to confirm sufficient preparation. Walls: An 8 litre kit of E-Poxy R when mixed with 230 grams of E-Thickener will provide a non-sag wall coating of 100 microns thickness per coat applied with a short nap roller. Halve this quantity for a 4 litre pack. Epoxy Screeds: E-Poxy R may be applied to Adcrete’s epoxy resin screeds. High spots or trowel marks should be rubbed down and dust and other debris removed by vacuum cleaning.
MIXING: Stir Part A and Part B components prior to mixing. Add the Colour Pack to the Part A component and mix thoroughly using a low speed electric drill and suitable spiral mixer for 1 minute. Add Part B component and mix for a further 3 minutes. For wall applications Thickner can be added into the mix at the same stage as the Colour Pack component addition. To maximize pot life pour mixed components into a tray before application.
Application: 1st Coat: Following the required preparation, apply E-Poxy R by brush or roller at a minimum rate of 7-8m²/litre. When an anti-slip finish is required, the appropriate grit should be applied as soon as sufficient area has been coated. The anti-slip granules should be lightly and uniformly broadcast over the wet E-Poxy R. The size and distribution rate of the grit should be in accordance with that prior agreed to by the client or their representative. If any areas have lost gloss, recoat lightly before applying grit. When the first coat is hard (usually next morning –refer re-coat times in “Typical Properties” section) sweep or vacuum off all excess grit. For good appearance and easier cleaning, it is important that all loose grit be removed at this time. Adcrete Industries offer the following choice of grit. • Fine - S425 • Medium - S30/60 • Course - S18/40 2nd Coat: Mix the components as before and using a paint roller (deflocked mohair is recommended) apply a coat over the grit. It is important that this final coat be uniform by the exact ratio of application may be varied to suit the finish required. A heavy final coat will provide an easily cleaning floor whereas a fairly light coat will give the best slip resistance in wet conditions.
Brushes and rollers should be washed thoroughly at least once each hour, with mineral turpentine or Solvent T making sure all solvent is removed before reusing again. Brushes and roller should be discard after use. At temperatures of 20-30°C foot traffic may be permitted after 24 hours, and light vehicular traffic after 72 hours; however, in cold weather a longer period before use may be required. Do not apply below 10°C. Allow 5-7 days before subjecting to chemical attach or abrasion.
LIMITATIONS:
E-Poxy R should not be applied to any surface subject to back water pressure; otherwise failure of the bond is likely to occur. Intending users should always consult Adcrete Industries Pty Ltd if there is any doubt as to whether a proposed application may involve conditions other than “ordinary”. Such extraordinary conditions include Porous or poor quality concrete causing excessive use and absorbency of the product. Unusually cold condition during curing (<10°c) 61656="" elevated="" temperature="" of="" service="">40°C) eg. Floors subject to hot water Severe, or unusual chemical attack Severe, or unusual conditions of service beyond the limiting physical and chemical properties of epoxies. Care should be taken in selecting colours as some will darken or develop a brown tinge when exposed to sunlight or certain chemicals. This effect is noticeable on white, light coloured and grey systems; on brown, yellow and red colours it is less noticeable. E-Poxy R is not recommended for exterior use where it is subject to sunlight or in applications involving prolonged chlorinated water immersion. E-Poxy R should not be applied on to surfaces known to suffer from rising damp or having a relative humidity reading greater than 80%. Refer to Adcrete Industries Pty Ltd for further advice. E-Poxy R should be applied only when the substrate temperature and the ambient temperature is above 10°C. E-Poxy R is not recommended as an application over tiles. Solvent must not be added to E-Poxy R under any circumstances unless agreed in writing by Adcrete Industries Pty Ltd Technical Department for specific applications. Some solvents, including acetone and methylated spirits will significantly affect the curing and intercoat adhesion of epoxies.
CLEANING:
All tools and equipment should be cleaned immediately after use with either mineral turps or solvent T. Hardened material can only be removed mechanically.
