1 PHC LINER, anti-acid, anti-osmotic, eco-friendly, and washable for protection coatings on porous materials 22-12-2010 IBIX Agents’ EOY Meeting AUTHORS: Engineer MARGHERITA PRIOLO Mr. MATTEO RAVA

2 2 Liner: the cutting-edge coating solution for porous materials INTERNATIONAL PATENT New frontiers.. PHC LINER

3 PHC Liner: the cutting-edge coating solution for porous materials WHAT IS PHC LINER? It is synonymous of a 100% self-supporting, perfect coating anti-osmotic barrier isolate A perfect coating has to be an anti-osmotic barrier in order to isolate substrates against the external agents the coating is exposed to. concrete, fiberglass and porous materials in general. For this product specifically, the substrates to be protected generally consist of concrete, fiberglass and porous materials in general. 3

4 PHC Liner: the cutting-edge coating solution for porous materials Concrete - Typical Characteristics Concrete Concrete is a composite material that deteriorates when exposed to normal environmental conditions. At the casting stage, concrete is sensitive to climatic changes and absorbs gases present in the atmosphere. We should not overlook the fact that concrete 'breathes', so it expands and shrinks with seasonable moisture and temperature variations, and this often causes cracking problems. surface morphology Other peculiar and negative characteristics of concrete are a non- uniform, changing surface morphology as well as the typical porosity of the finished body. 4

5 PHC Liner System compared with Coating Resins COATING RESINS such as polyureas and epoxies DO NOT guarantee a long-lasting protection when applied on concrete substrate since they present both application and intrinsic problems. Productive systems have flaws such as: no control over ambient conditions when product is applied (air moisture, wet substrate, air and substrate temperature, etc.). Application cycles are hard to control (flash period, drying, weathering, etc.) Unchanging thicknesses in surface morphology cannot be guaranteed (pitting, roughness, etc.) Therefore, this coating DOES NOT guarantee anti-osmotic properties as gases and liquids can pass through it. When these elements reach concrete, the result is early corrosion. 5

6 SOLUTION THE PHC LINER OFFERS The SOLUTION THE PHC LINER OFFERS: 6 In theory, the main aim of any coating is to create an impermeable barrier that protects the substrate against any kind of aggression. The chose coating must guarantee adhesion, resistance to chemicals and physical agents, elasticity, and long-term stability. PHC LINER: The idea finds its roots in the proof that traditional painting systems (using liquid varnishes) CANNOT GUARANTEE lasting performance, especially when used on porous substrates such as concrete.

7 PHC Liner: Key Factors to Success Highly flexible and versatile system Several PHC Liner models The avant-garde production technology applied allows offering a wide variety of copolymers. A vast choice of products are available to meet the requirements of various market segments Special versions: Cuspidal version (with pre-shaped cusps suitable for the hook to be buried in concrete and to be installed at the concrete casting stage); Version with metal reinforcement (also suitable for providing the hook to be buried in concrete and to be installed at the concrete casting stage); Non-slip version Photo-luminescent version Anti-bacterial version Abrasion-resistant version 7

8 8 IBIX PHC Liner, non-slip version. Repairable. IBIX PHC Liner, cuspidal version, ready to be installed during the concrete casting stage. Viable LINER versions

9 PHC LINER: Product Description Chemical & Physical Characteristics : Resistance to penetration of liquids (anti-osmotic characteristics) Enhanced smooth fluidity ('waxed' effect); Excellent resistance to chemicals (acids, alkali, solvents) Excellent resistance to adverse weather conditions Excellent behaviour in case of fire (material that would not easily catch fire) Anti-bacterial and anti-fouling properties (special formulations) 9

10 10 Mechanical Properties: Abrasion-resistant (Taber ASTM 60mg/500g) Remarkable elastic properties (ultimate at break: 500%) Resistance to cold (-70°C) Technical Characteristics: Leak-tight joints and connections Easy to repair if accidentally damaged (THERMOplastic) No porosity

11 11 Colour range Our colours are:  695 Ral 7045 (grey)  536 Ral 5017 (blue)  110 Ral 9016 (white)  700 Ral 9005 (black)  Natural (transparent) Other colours can be made upon customer's request

12 12 Let's see how to apply the product in detail Sub-base inspection: First, take a close look at the surface where the coat will be applied. The substrate should show no friable, fragile, or loose parts. It should be intact, firm and solid; any potential deformation should be foreseen before applying the coating.

13 13 Any substrate deformation or unevenness, warping or irregularity should be solved before the adhesive is applied. Do not use the adhesive to compensate for these faults. Carefully check that there are not any release agents such as release oils or any other element that can adversely affect adhesion.

14 14 Finishing coats Apply a skim coat of mortar if concrete is irregular. We recommend Kerabuild, a monocomponent cement-based mortar formulated for deep filling, to restore or repair damaged or missing sections in cement and masonry. Excellent product workability to fill surfaces, even if imperfections are deep, when the coat is spread and finally laid by trowel. Moisture: Due to the characteristics of the adhesive, the substrate where it is applied should be dry and free of rising damp. Damaged concrete

15 15 Once you have checked that the sub-base is solid, measure the moisture content. It should not exceed 3%, the same as for laying any other flooring. If over 3%, use any specific equipment that can adequately warm up or dry the floor Recommended glue: bi-component SLC PU70 glue

16 16 BASIC LAYING CONDITIONS REQUIRED Clean and firm sub-base Negative roughness 3-4 mm max Max moisture: 3% Minimum room temperature: 13°C

17 PUMP TO APPLY IBIX SUPERGLUE 17 An effortless task Single-phase supply

18 18 Applying glue using the pump

19 19 How to lay the plates Follow the same steps as for any other resilient flooring. How to apply the glue: use a pump spraying system if the area is very large (about 1sq.m / min), or spread by hand (with a saw-toothed scraper, 1 mm) Plates are to be laid head to head. Standard sizes: 1x2 m or 1x1m, different thicknesses depending on the customer's request, from 1.5mm to 2mm; 2.5mm thick for the anti-slip version.

20 20 ROLLING: Once the plates are laid (should coincide with one another; maximum deviation allowed: one millimetre), they should be rolled using a specific loaded floor roller. Purpose: The roller presses the liner onto the surface underneath so as to improve adhesion and eliminate any air that may be trapped

21 21 WELDING: Once the 24-hour drying period has elapsed (do not walk on the surface during this time), weld the plates one to the other. Welding Methods Used:  Extrusion welding gun  Hot-air welder, once plates are milled. Floor uniformity (for both welding technologies) is given by a weld bead of the same material (PHC) and colour. The final result is a seamless floor.

22 22 This extrusion system joins PHC Liner sheets by applying the same material (PHC) via extrusion. Suitable for welds that have to endure continuous stress. Welds are tear resistant and have the same flexibility to breaking stress as the original PHC Liner sheets. Automatic fan to blow hot air, suitable for preparing PHC Liner sheets to receive the extruded material Double check for fan and extrusion chamber temperatures Teflon tip that can turn 360° Extrusion welding gun R-SB 50 to weld PHC Liner

23 23 Welding material in several colours This is how the extrusion-welded Liner plates look like

24 24 Welding using a hot-air welder Manual milling machine that drills a groove where the weld bead is melted Automatic welder that melts the weld bead in the groove

42 42 Work-with Ambient Conditions: Thermal gradient: - 0° inside the anteroom - Rooms at controlled temperature - work-with temperature was about 10 ºC; this temperature was obtained by keeping the anteroom door open the whole night before the product was applied. Floor underneath: - Ceramica tiles Area to cover: 28 sq.m

43 43 Laying and glueing

44 44 Despite the low work-with temperatures, using a hot-air blower we managed to minimise the floor rising damp and to increase the room temperature so that the glue can adhere. Welds were made 24 hours after the product was applied

47 47 Finished job

48 48 LINER CLEANING Cleaning the Liner is easy and simple- just wash it on a regular basis with floor scrubber and regular floor detergent. You can also wash it with a high pressure water jet cleaner. Never use steam or hot water to wash it; in case you need to use hot water, water temperature should never be over 40. If dirt has caked onto the Liner, wash using an IBIX9 H2O sand-blaster and bicarbonate, and the Liner will not be affected.

49 49 Anti-acid applications in pre-galvanising pre-processing plants (hydrochloric acid tanks) Hydrochloric acid dissolves almost any metal, and it is also the cause for concrete weakening as calcium ions are removed from the silicate hydrates that form the main concrete binders. And so, concrete becomes decalcified. On the contrary, in metals such as steel, the action of these gases leads to continuous corrosion, also inside the metal core. Over time, the floor or the supporting metal structures will undergo a slow but significant thinning process.

50 50 Solution suggested Our solution is to apply a protection coating/lining, 100% insulating and acid- resistant, on the floor and the internal walls of the building. We recommend PPA571 coating to be applied on metals using a fire-spraying system, and a panel pattern (Liner) on floors. If applied on floors (PHC Liner system with gluing, once the substrate is clean).

51 51 Liner applied at FRIGO GENOVA The solution suggested is a protection coating/ lining, 100% insulating and resistant to heavy traffic of forklift trucks and staff. Resistant to sudden temperature changes and that 'moves' together with the floor underneath, that does not crack or get spoiled as traditional resins.

52 52 Liner applied in veterinary clinic in S.Biagio The solution suggested is a protective coating, totally insulation and resistant.
