Car Body Pre-Treatment
Filtration plays an important role in the degreasing and pre treatment process carried out prior to the paint process. Cars bodies coming from the assembly plant will be contaminated by oil, metallic weld splatter and general debris. These will be transferred to the recirculating degreasing liquids during the cleaning process and will need to be removed by filtration. DuoLine filter bags rated at 50 – 100 µm including the special oil absorbing DuoLine OilOut range are excellent for this application. Filtration is also key for maintaining the quality and effectiveness of rinsing water and the phosphate pretreatment solutions. Products used for these applications are DuoLine filter bags, SupaSpun II filter cartridges and SupaPleat FFC filter cartridges for larger systems. Typically they will be rated at 50 – 100 µm.
Electrophoretic Paint (E-Coat)
Designing an effective E-coat process is key to achieving a high quality final paint finish. Filtration is a critical part of the E-coat process and is typically required to remove poorly dispersed paint, hardened resin, skin fragments and general debris that may contaminate the bath. This is a challenging application and Amazon Filters has specifically designed a range of cartridge and bag filters to help ensure the E-coat is free from defects. Typical products used to filter the E-coat paint are DuoLine filter bags rated at 25 – 50 µm and Contour filter cartridges rated at 70 – 100 µm absolute. Post E-coat rinsing water is typically filtered using SupaPleat FFC cartridges rated at 50 – 90 µm.
Sealant Deck / Mastic Application
PVC sealants, waxes and mastics, used to prevent water ingress and corrosion of joints and spaces, are highly viscous and high pressure systems are required for their application. Filtration of these products is vital to prevent blockage of the gun nozzles, but with viscosities of 70,000 – 100,00 cP this presents a particular challenge. To address this Amazon Filters has developed a special high strength stainless steel cartridge and the high pressure 59 Series housing. The system is suitable for pressures up to 350 bar and filters are available with ratings between 400 and 1200 µm to ensure optimum protection for the gun nozzles.
