R&D activities play the key role in IBA Kimya for progress and success.
Our R&D team, composed of expert chemical engineers, conducts the search for new technological developments and utilize them in formulating high class, environmentally friendly products.
IBA Kimya product development studies are carried out in the sophisticated laboratory equipments. The attained recipes are further verified in the pilot application plants through trial runs.
Our R&D and Technical Service departments are in close relation with customers through all stages of production, from product development till application, in order to provide them with the best solution. IBA Kimya is a corporate partner to all of her customers in terms of problem solving.
By differential scanning calorimetry (DSC) analysis can be advantageously obtained by using DSC analysis versus alternative methods (gel time, solvent cure test, storage stability etc.) Information such as the glass transition temperature (Tg) and the cured film temperature (Cured Tg) values of the powder coating and the stock stability of the powder coating, the softening property of cured film when subjected to temperature, the kinetic properties of the coating as well as information such as cured paint film is sufficiently or excessively cured or inadequately cured are obtained.
The gradient-oven is a test apparatus for evaluating the baking behavior of powder coatings. The gradient oven consists of 45 heating elements each micro-processor controlled. A linear gradient or step gradient can be programmed to precisely determine the cure temperature. The ramp up temperature rate and bake time can also be programmed to similuate customer application conditions, and give us information on how coated film behave at different curing conditions such as chemical resistance, impact resistance, overbake yellowing etc.
During curing conditions powder coating particles first melt and hence wet the substrate. As temperature and time increase, due to thermosetting reaction, gelation occurs. The change in viscoelastic behaviour due to temperature during curing can be evaluated with a rheometer. In this way, the melting and gelation temperatures of the coating, as well as the viscosity values during curing, can be calculated.
The Raman effect allows fast, non-destructive chemical analysis of solids, powders, liquids, and gases – today, Raman spectroscopy is used in many varied fields. In powder coatings raman is used to determine causes of surface defects on coated films, lead pigment amount in powder coatings and for special materials.
Salt Spray Test
This is a laboratory test that measures corrosion resistance of organic coated metal material. Both pretreatment and coating properties affect the results.Although no definite one to one match can be made between the end result of the test and the real time duration of use, according to ISO 12944, salt spray test can give a directional correlation with the results of the corrosion classes from C2 to C5. The material is exposed to 5% Sodium Chloride (NaCl) solution at 35 ° C continuously in salt water test, whereas in real life it is exposed to different ratios of humidity, temperature and ionic interactions. Tests are made according to ISO 9227 standard in our R&D Department.
It is used to evaluate the humidity resistance of coated material in constant varying condensation water environments. In accordance with the ISO 6270 standard, materials are tested according to the customer's request CH (constant humidity humidification environment), AHT (changing humidity and air temperature humidification environment) and AT (changing ambient air temperature humidification environment) selection.
This is an accelerated corrosion test for Qualicoat, and commonly used in Eurpe. Salt spray testing takes typically 500 and 1000 hours. This can slow down the development work in R&D laboratories. The machu test offers a possibility to shorten 1000 hours of salt spray testing into a 48 hour evaluation period. Since the test conditions are quite severe, the Machu test results are slightly inferior on average to the corresponding salt spray results; i.e. if it passes the Machu test, it will most likely pass salt spray. Tests are made according to ASTM B117 standard in our R&D Department.
It is a device that measures dielectric strength according to coating thickness of powder coatings. It is used to determine the maximum voltage that the powder coated conductive material such as metal can protect its insulating property. Premature corrosion of a substrate is usually due to a coating failure. A major cause is the presence of flaws in the finished coating, collectively referred to as porosity. Holiday test is used to detect holes, known as holidays or discontinuities, in a coating. Holiday testing allows the detection of even smallest coating flaws invisible to the naked eye.
Hydraulic Ahdesion tester
The Hydraulic Adhesion Tester is one of the most accurate and versatile adhesion testers currently available. It measures the adhesion bond strength of applied coatings with ease, and precision. The adhesion is measured by the tensile pull on a Dolly glued to the coating surface. The force is applied through the centre of the Dolly by a hydraulically loaded pin. This ensures an exactly central point-loading of the force.
This is ash oven that can be operate at 25°C to 1100°C temperature range. The resistance of high temperature resistant powder coating products such as EE56, SL54 is tested with this oven.
It is a device developed to regulate real climate conditions by controlling cycles such as temperature and humidity. Time and humidity programming can be performed to observe the behavior of the powder coating placed in constant temperature, under conditions of without humidity or relative humidity up to 98% and temperature range of -40°C to 150°C, where stability, artificial aging, storage and shelf life tests can easily be performed.
Electrical Conductivity Measurement EN 61340
Normally all the powder coatings are insulative. But as Iba Kimya we also produce conductive and antistatic (ESD: Electro static dessipative) products upon request. Surface resistivity of coated panels can be measured in Ohm/sq to determine its conductive properties.
Accelerated UV Weathering Test
Iba Kimya uses two different Q-UV equipment and one Xenon Test Chamber to simulate the effect-deformation of rainfall and full-spectrum sunlight on the coated surface over several days or weeks, for months or years. Q-UV tests can be made by B313, A340, A351 lambs. Our Qualicoat and GSB approved series are continously tested with B313 and WOM.
