KG, Detmold (Germany), <br />to test the bond behaviour of the primer <br />INDUFLOOR–IB 1270 <br />under the influence of moisture at the reverse side. <br />The test was carried out in accordance with <br />DIN EN 13578 <br />“Products and systems for the protection and repair <br />of concrete structure - test method - compatibility on wet concrete”</p> <p>2</p> <p>RECEIPT OF SAMPLES <br />The sample was delivered on 2012-01-17 by post at the Polymer Institut. <br />table 1:</p> <p>receipt of samples</p> <p>no.</p> <p>material</p> <p>1</p> <p>INDUFLOOR-IB 1270</p> <p>component</p> <p>charge</p> <p>quantity [kg]</p> <p>A+B</p> <p>0120248</p> <p>3.0</p> <p>The top sealing on epoxy-base was taken from the stock of the Polymer Institut.</p> <p>Page - 4 -</p> <p>of 9 pages of the test report P 7588-2-E <br />dated 2012-04-30</p> <p>3</p> <p>PREPARATION AND STORAGE OF THE TEST SPECIMEN</p> <p>3.1</p> <p>Preconditioning <br />With the customer a minimum processing temperature (MAT) of 10°C has been agreed. <br />The Preconditioning of the concrete substrate bodies and the coating material was carried <br />out in detail by the flowchart according to the picture 2 of the DIN EN 13578.</p> <p>3.2</p> <p>Preparation of the mixture of the components <br />The mixing ratio of the components for the coating material used is to be taken from table <br />2. <br />table 2:</p> <p>preparation of the mixtures of the components <br />material</p> <p>INDUFLOOR-IB 1270</p> <p>mixing ratio in parts by mass <br />component A</p> <p>component B</p> <p>100</p> <p>27</p> <p>The materials were measured out in the above mixing ratio and mixed to homogeneity <br />(for about 3 min).</p> <p>3.3</p> <p>Application <br />The application of the single coating materials has been carried out by an employee of the <br />Polymer Institut. The concrete substrate bodies MC (0.40) according to EN 1766, which <br />have been wet-stored at 10°C were taken out from the water bath, their surface has been <br />wiped with absorptive tissues and the specimens were brought into a vertical position. <br />After a waiting time of 2.5 h, the priming coat has been applied onto the specimens. Between the application of the primer and the application of the subsequent layers, the <br />specimens were stored in a water bath lying on a lath floor in order to keep the water <br />level 10 mm under the coating section (see image 1).</p> <p>Page - 5 -</p> <p>of 9 pages of the test report P 7588-2-E <br />dated 2012-04-30</p> <p>image 1:</p> <p>3.4</p> <p>storage of the test specimens in water</p> <p>Coating system of the composite specimen <br />The consumptions (mean values) are to be taken from the following table. <br />table 3:</p> <p>coating of the substrate specimens <br />consumption in [g/m²] <br />- mean value layer</p> <p>sample-No. <br />3, 4, 7, 8 <br />application <br />tool</p> <p>primer</p> <p>top sealing</p> <p>INDUFLOOR-IB 1270</p> <p>top sealing on <br />epoxy-base</p> <p>1. working step</p> <p>2. working step</p> <p>225</p> <p>225 <br />roller</p> <p>approx. 2000 <br />tooth comb</p> <p>Page - 6 -</p> <p>3.5</p> <p>of 9 pages of the test report P 7588-2-E <br />dated 2012-04-30</p> <p>Stress Procedure <br />After the application of the coating material the slabs were stressed as follows: <br />table 4:</p> <p>stress procedure</p> <p>specimen <br />number <br />2 <br />2</p> <p>substrate <br />MC <br />(0.40)</p> <p>stress procedure <br />hardening</p> <p>storage</p> <p>laying in water*</p> <p>in water*</p> <p>on air</p> <p>climate <br />[°C / % r.

The pull-off tests were carried out using a calibrated <br />tensile tester of the company Freundl, type Easy-M, with constant increase of load of <br />100 N/s. <br />The test results are to be taken from the following table.</p> <p>Page - 7 -</p> <p>of 9 pages of the test report P 7588-2-E <br />dated 2012-04-30</p> <p>table 5:</p> <p>specimen</p> <p>pull-off strength after 56 days storage at 23°C - reference test specimen <br />system with the primer INDUFLOOR-IB 1270 <br />no. <br />1 <br />2 <br />3 <br />4 <br />5 <br />1 <br />2 <br />3 <br />4 <br />5</p> <p>7</p> <p>8</p> <p>mean value <br />lowest single value <br />table 6:</p> <p>specimen</p> <p>pull-off strength <br />[N/mm²] <br />2.9 <br />2.3 <br />2.7 <br />3.1 <br />3.8 <br />2.9 <br />2.4 <br />2.7 <br />2.7 <br />2.4 <br />2.7 <br />2.3</p> <p>fracture surface [%] <br />B <br />30 <br />20 <br />10 <br />60 <br />30 <br />30 <br />10 <br />20 <br />30 <br />20</p> <p>AOS2 <br />70 <br />80 <br />90 <br />40 <br />70 <br />70 <br />90 <br />80 <br />70 <br />80</p> <p>pull-off strength after 56 days storage at (8 ± 1)°C and (75 ± 10) % r. h. <br />system with the primer INDUFLOOR-IB 1270 <br />no.</p> <p>3</p> <p>4</p> <p>mean value <br />lowest single value</p> <p>1 <br />2 <br />3 <br />4 <br />1 <br />2 <br />3 <br />4 <br />5</p> <p>pull-off strength <br />[N/mm²] <br />1.4 <br />1.0 <br />1.0 <br />1.0 <br />1.6 <br />1.8 <br />1.6 <br />1.9 <br />2.2 <br />1.5 <br />1.0</p> <p>fracture surface [%] <br />B <br />20 <br />10 <br />10 <br />10 <br />10 <br />20 <br />10 <br />10</p> <p>AOS2 <br />80 <br />90 <br />90 <br />100 <br />90 <br />90 <br />80 <br />90 <br />90</p> <p>legend: <br />B: <br />cohesive fracture in concrete <br />AOS1: adhesive fracture between concrete and INDUFLOOR-IB 1270 <br />AOS2: adhesive fracture between INDUFLOOR-IB 1270 and the top sealing on epoxy-base</p> <p>Page - 8 -</p> <p>4.2</p> <p>of 9 pages of the test report P 7588-2-E <br />dated 2012-04-30</p> <p>Visual examination <br />During the whole period of stressing and immediately after finalization (after 56 days) the <br />test specimen were examined visually in regards to eventually noticeable changes of <br />characteristics of the coating compared to the dry-stored specimen. <br />Visible changes in the coating in terms of <br />blisters, cracks and exfoliation <br />are evaluated according to <br />-</p> <p>ISO 4628-2 (evaluation of the degree of blistering) <br />ISO 4628-4 (evaluation of the degree of cracking) and <br />ISO 4628-5 (evaluation of the degree of exfoliation)</p> <p>with an evaluation scale from 0 - 5 for quantity and dimension of the alterations: <br />0 <br />5</p> <p>lowest value / no changes <br />heavy changes / high volume</p> <p>Result <br />The test specimen stored in water at (8 ± 1)°C and those stored under standard atmosphere condition did not show any changes on top of the coating, that means according to <br />ISO 4628 <br />-</p> <p>no blisters (0) <br />no cracks (0) <br />no exfoliation (0)</p> <p>Page - 9 -</p> <p>5</p> <p>of 9 pages of the test report P 7588-2-E <br />dated 2012-04-30</p> <p>SUMMARY <br />Polymer Institut was charged by SCHOMBURG GmbH & Co.
