ra Life : For Powder Coatings and Wet Paint
Preparation Coating systems are only as effective as the surface to which they are applied. Therefore, correct preparation is essential to ensuring the system achieves its design life. Relevant instructions can found on the product data sheets. With ra Life, particular attention should be paid to problem areas such as: Sharp edges Weld seams Fixings Cromadex recommend that these areas are always stripe coated prior to application. Care and maintenance Industrial coatings are no different to the paint on your car they need cleaning and maintaining. Accumulated dirt may affect the design life of the system, and any mechanical damage almost certainly will. Therefore regular inspections should take place and minor damage must be touched up. At the end of the design life, major maintenance must be carried out. This includes spot priming where necessary, and as a minimum, rubbing down and applying a full coat of the original topcoat when wet paint was used. If powder was originally applied then a suitable Cromadex wet paint system should be used. Please contact your nearest Cromadex Centre for the necessary technical advice. Technical support For further technical information or advice on any of the ra Life systems please contact your nearest Cromadex Centre. Reducing environmental impact It is an AkzoNobel policy that all erpon Powder and Cromadex Wet Paint products are free from lead chromate pigments and TGIC (triglycidyl isocyanurate). The Cromadex Wet Paint systems also include waterbased and isocyanate-free options.
ra Life - Design to Last ra Life is a programme of coating systems that offers product protection for up to 2 years for wet paint and up to 16 years for powder coatings. These systems have been developed to protect against a wide variety of environments, from the interiors of heated buildings to much more aggressive external situations, such as industrial or coastal areas. ra Life for wet paint encompasses standard air drying or stoving products, to the latest developments in two pack technology. ra Life for powder coatings incorporates the latest powder primer technologies. There are three steps to specifying the correct ra Life system. 1. Identify the environment 2. Determine the design life 3. Select the correct coating system a) Powder b) Wet Paint 1. Identify the environment ra Life has six key environment classifications. Select the environment where your product will be used. If in doubt, select the more aggressive environment or call Cromadex for advice. 2. Determine the design life Choosing the right durability is a question of cost. If the system doesn t last long enough, rectification could be expensive. However, with ra Life, you can be specific in terms of the durability and investment required. With the test data and track record we have, the durability of each system can be given in terms of years which enables a more accurate coating specification for both powder and wet paint systems.
