Our preferred process to remove paint from aluminium extrusions and components is WR-STRIP. (European Patent 0860479) This is a low volatility stripping medium based on Benzyl Alcohol. It is designed to remove polyester and epoxy polyester powder coatings from most metals with minimal attack on the base metal. Unlike some benzyl alcohol based strippers which can attack alkali sensitive metals. Used at lower temperature (40-50°C) than other hot stripping products. WR Strip is less susceptible to loss by drag out. It has a reduced rate of loss by evaporation. No messy expensive oil seals are necessary to control fumes. It has proven extended bath life. There is a lower overall chemical usage. WR Strip is Inhibited to minimise attack on Aluminium substrates. Stripped components are cleaner than using Methylene Chloride based materials. Unlike pyrolytic stripping it is possible to strip spring tipped jigs. WR Strip is made from biodegradable solvents which are not classified as Toxic or Flammable. Does not contain Methylene Chloride (Dichloromethane), Methanol, Phenol, 2-butoxyethanol, or Monoethanolamine. The process is more acceptable to Water Authorities for rinse water disposal. When continuously filtered, there is much less expensive Hazardous Waste to dispose of. The constituents are not listed in EH/40 as having a maximum exposure limit. There is a very low VOC content as defined by the European Solvents Directive. No constituent has a risk phrase of R40, R45, R46, R49, R60 or R61. The need for expensive extraction is reduced.
Packaged and bespoke solutions – depending on the volume of wheels to be stripped.There are three distinct approaches all using dip tanks: (1) Cold strip using ambient temperature Methylene Chloride based acid solutions. No agitation required. Produces sheets of paint residue which are manually removed. Uses hazardous materials and waste products have to be tightly controlled. (2) Hot strip using Benzyl Alcohol based solutions. No agitation required. Produces sheets of paint residue which are manually removed. (3) Hot strip using Benzyl Alcohol based solutions Produces particles of paint residue which have to be removed using a filter press.
Stripping polyester powder, epoxy-polyester powder and wet paints from jigs and steel components is our business. BJ-STRIP is the preferred material and has the following benefits: Speed: BJ-STRIP is much more strongly alkaline than WR-STRIPSuitable for use with multiple coatings. Does not cause heat distortion. Does not detemper spring loaded jig tips. Does not alter dimensions of threaded components. Can be completely drained from difficult profiles, unlike fluidised beds which can retain sand and ovens which can retain ash. BJ STRIP can be used to remove difficult coatings from aluminium, but only under controlled conditions, which prevent water contamination of the bath.
