1. RIVERINA SEALING SOLUTIONS INDUSTRIAL ANTI-ABRASIVE “ I.A.A.™” Abrasion and Corrosion Protection of Industrial Plant and Machinery

2. Introducing I.A.A. ™  User Friendly v Latest Technology v Economical

3. What is I.A.A.™ ?  I.A.A Polyurethane's are sprayed at low pressure, and cure at ambient temperature. They are not high pressure and heated  “ I.A.A.™” is a 100% solids, urethane elastomer  It is spray-applied to provide a continuous monolithic coating or lining  Protects expensive infrastructure with a permanent seal  For maximum bonding apply to 60 profile blasted steel. The I.A.A.™ will become ‘as if one’ with the steel  Provides excellent mechanical abrasion resistance  Provides extremely high rebound resilience

4. Features and Benefits of I.A.A™  I.A.A.™ has exceptional adhesion, durability and water impermeability under extremes of climatic conditions  Highly flexible to allow for substrate movement  Spray-applied at low pressure, moisture tolerant and rapid cure, gels in 30 seconds  Single coat application  can be applied to heavily rusted or gouged surfaces with a minimum preparation to provide a rejuvenated finish

5. Features and Benefits of I.A.A.™  High tensile strength and flame resistant  Hydrolysis, mould, mildew, and fungus resistant  Suitable for protection of machinery in contact with seawater, industrial water, waste water and acid soils  Thermal stability - Elastic at temperatures between -20°C and 80°C  Resistant to corrosion-causing chemicals, oil, fuels and solvents  Resists abrasion, cutting, gouging and water penetration

6. Applications of I.A.A.™  Loaders and excavators  Shaker screens, ball mills  Augers, silos and bins  Clutches, hoppers & wear plates  Abrasion protection for steel, concrete and most other surfaces  Tanks, concrete mixers, vibrating equipment  Ore concentration spirals, cones, floatation cells  Tailing Dams, Retention Tanks

11. I.A.A.™ 10 Year Wear Test Results I.A.A. was applied to a spiral separator in a soda ash plant in 1993. Half m2 sample was taken after 10 years service, it was tested for strength, wear etc with these results

12. I.A.A. is used extensively in mining applications in Australia over steel bins, chutes, hoppers etc. One of the best examples of this is possibly a vibrating schenck screen deck for Bulga Coal Hunter Valley. In this application there is constant vibration and water present. At CSR in Melbourne I.A.A. has been applied at 6mm DFT to aggregate chutes and hoppers. After 6 months @ 11 tonne of 30 mm aggregate per hr constant use, wear test results on the hoppers and chutes for DFT of remaining I.A.A. determined a min average of 4mm thickness. I.A.A. consistently out performs tiles and rubber linings (e.g. in fans, floatation cells etc) at approximately a 4 to 1 wear factor. I.A.A.™ I.A.A.™ Some other examples of Use

14. Health and Safety Under normal conditions of use and the application of good industrial housekeeping/hygiene this product does not present a significant health hazard. The VOC specification is 0%, however, should the material be splashed on the skin it should be removed by copious irrigation with clean water followed by washing with warm water and soap. Following eye contamination, copious irrigation with clean water to remove the material from the eyes, the person should be medically examined. Following ingestion, medical advise should be sought. As in any spaying procedure the aerosol or mist produced while applying this material can be hazardous to health. Operators should there for be protected with air-fed full-face masks and if the system is being applied indoors, masks should be used in conjunction with a high volume extraction system. The dust produced while grinding or pulverizing the cured product is similarly hazardous if inhaled. In this situation the same safety procedures should be followed as above in the application process. Correct Personal Protection Equipment should be worn. Also refer to the Material Safety Data sheets.
