Preparing the component It must be ensured that the surface upon which the foam will be applied is free of grease, release agents or any contaminations, because this would adversely affect the adhesion. In addition, the temperature of the component and the environment and storage conditions can affect the hardening speed and the adhesion properties. Based on experience, FERMAPOR K31 systems adhere well to powder-coated surfaces. However, when assessing the adhesion quality, the applied material is not the only key factor. The surface upon which the foam is to be applied also plays an important role. In addition to the type of coating used, other parameters such as curing duration and coating temperature also influence the adhesion. Therefore, it is recommended in all cases to perform an adhesion test in advance using the relevant components. If there is no adhesion, it is possible to carry out pre-treatment with plasma, corona, flame or primer. Feel free to contact our Application Technique Division if you have any questions (see pg. 6 for contact information). Preparing the material The A-component must generally be charged with air. The A-component is air-charged inside the one- day container of the processing machine and can be controlled both manually and automatically. Thixotropic, unfilled A-components with a viscosity greater than 35000 mPa*s, do not require stirring prior to use. B-components do not require an additional air-charging treatment. It is also not necessary to stir them in advance.
