FIPROPHOS 509 is a liquid phosphating agent for the pre-painting treatment of ferrous material.
FIPROPHOS 509 effectively removes processing, protective and molding oils from metal surfaces, simultaneously developing a phosphate coating of 3-8 mgr / dm2 ideal for anchoring paints. To increase the degreasing power and duration of the solutions, it is possible to add the degreasing additive FIPROPLUS 701.
3.5 - 5.5
Behavior in hard water
Usage and Applications
FIPROPHOS 509 10 -30 g / lt, 35 - 60 ° C; pH 3.5 - 5.5
Rinse with cold running water.
Passivation with FIPROPLUS 704 conc. 0.3 - 0.6% and temp. environment.
In order to avoid oxidation problems, make sure that the pieces are then dried as soon as possible.
To increase the degreasing power, the additive FIPROPLUS 701 in a concentration of 0.1-0.4% can be added to the solution.
Preparation of the solutions
Slowly pour the product into warm or hot water. The construction materials of the plant must be in stainless steel.
Control of bathing
Deposition of a homogeneous protective substrate
Easy to start and run process
Low environmental impact and non-hazardous products
Increased hours of salt spray
Increased adhesion of paints and coatings
Preconversion or final treatment
To obtain the concentration in g / l, multiply the value obtained by the fixed number “3.3”.
Then bring the concentration to the required value, adding 3.3 Kg of product per 1000 Lt. of bath for each missing point.
