Paint Line Products

Cleaners

Kleen 4010 is a liquid, strongly alkaline cleaner specifically formulated for use on continuous strip coil lines. It is designed to remove a variety of soils on aluminum, galvanized, and steel substrates. Kleen 4010 will produce effluent, which is easily waste treatable. This product is designed to produce minimal foam, even at low cleaner bath operating temperatures (<120°F, 49°C). Kleen 4010 contains sequestrants to minimize cleaner bath sludging and nozzle pluggage.
Kleen 4000 is a liquid, strongly alkaline cleaner specifically formulated for use on continuous strip coil lines. It is designed to remove a variety of soils on aluminum, galvanized and steel substrates. Kleen 4000 will produce effluent which is easily waste treatable. This product is designed to produce minimal foam within recommended operating temperature range. This product is formulated with sequestrants to minimize cleaner bath sludging and nozzle pluggage.

Pretreatments — Conventional

Gardobond R 2955 is a phosphating process on the basis of Zn-Ni phosphate for hot-dip galvanized steel and electro-galvanized steel. Phosphate coatings obtained with Gardobond R 2955 constitute an excellent corrosion protection and substantially improve paint adhesion. Gardobond R 2955 is a pretreatment prior to the painting. These products are applied by spray or immersion.
chrome chromate for aluminum and Galvalume®

Pretreatments — Dry-In-Place

Chrome

mixed chrome, multi-metal treatment
Gardobond C 4571 is a chrome (Vl) containing dried-in-place process for strip and sheet steel, hot-dip galvanized steel, electro-galvanized steel, Galvalume, or aluminum and its alloys.

Chrome Free

titanium/zirconium for aluminum and HDG
titanium/zirconium for multi-metal applications
silanes, for multi-metal applications
Chromium-free no-rinse process for the treatment of strip or sheet made from aluminum and its alloys prior to assembly in the automotive industry. The process imparts the following characteristics:
  • Good weldability, low homogeneous electrical resistance
  • Good basis for adhesives (e.g. epoxy adhesives)
  • Surface suitable for auto body phosphating
  • Pre-treatment prior to primer painting (weldable primers i.e. Chemetall Gardoprotect products)

Mill Treatments

Cleaners

alkaline liquid, for steels, highly concentrated, low sludging
Kleen 4282A is a liquid, strong alkaline, electrolytic cleaner specifically formulated for use on continuous strip coil lines. It is designed to remove a variety of soils on steel substrates. Kleen 4282A will produce effluent which is easily waste treatable. This product is designed to produce minimal foam, even at low cleaner bath operating temperatures (<120°F {49°C}). Kleen 4282A contains sequestrants to minimize cleaner bath sludging and nozzle pluggage. This product is effective with anodic, cathodic, or alternating polarizations applications. Kleen 4282A does not contain ODCs or CFCs.

Passivation Treatments

mixed chromes for HDG, EG, Galvalume
mixed chromes, for HDG, EG, Galvalume, less staining, more stable
mixed chromes
tri-chrome for HDG, fluoride-free
non-chrome, removable, transit protection

Thin Film Organics (also known as Acrylics or Permanent Coatings)

Gardobond PC 4648/1 product is specifically formulated for the prevention of white rust and storage corrosion on zinc coated and zinc alloy coated steels. The coating provides anti-fingerprinting properties and enhanced roll formability without the use oils.
Gardobond PC 4649/1 product is specifically formulated for the prevention of white rust and storage corrosion on zinc coated and zinc alloy coated steels. The coating provides anti-fingerprinting properties and enhanced roll formability without the use of oils. Gardobond PC 4649/1 is totally Chrome free.

^ Both of above products available in various pigmented colors and transparent tints

Gardobond PC 4610/1 is a chromate containing organic coating system for the prevention of white rust and storage corrosion on zinc coated and zinc alloy coated steels. The Gardobond PC 4610/1 process improves corrosion protection, provides surfaces with anti- fingerprint characteristics, and improves performance in roll forming.

Fluids/Oils

dry film lubricant
Gardolube L 8250 is a skin pass fluid used in the production of galvanized coil stock during temper pass. Used in the correct concentrations, Gardolube L 8250 maintains clean rolls and prevents excessive roll wear. In addition, the product minimizes surface roughness of the galvanize. Gardolube L 8250 reduces compatibility problems when used in conjunction with the new generation of tri-chrome and non-chrome passivation products. After treatment with Gardolube L 8250 the material can be passivated or pretreated and painted in the normal fashion.
