Technical specifications
FIPROSTRIP 287 is a liquid paint stripper free of n-methylpyrrolidone (toxic substance), suitable for hot treatment in immersion and recirculating systems of painted iron, aluminium, zinc and alloy parts. Given the variety of materials that can be treated, however, it is advisable to carry out preventive tests.
Its balanced formulation combines high disintegrating power with a high swelling and paint release capacity.
FIPROSTRIP 287 is a product specially designed to remove powder coatings.
The product must not be placed in contact with water, as it is not compatible with it and would alter its characteristics.
Usage and Applications
The product is used pure, immersion or recirculation, and performs best at temperatures between 50 and 60°C. The contact time depends on the type and amount of paint to be removed, usually ranging between 20' and 120'.
Once the parts have been treated, rinse thoroughly with water.

Control of bathrooms
The liquor must be checked periodically and topped up if necessary in the event of a drop in application performance.
Take 5 ml of the bath sample, add 100 ml of demineralised water.
Add a few drops of phenolphthalein indicator.
Titrate with 1 N hydrochloric acid until the pink colour disappears.
The amount of acid consumed for the colour change gives the bath score, which should be between 3.6 and 4 and never below 2.5.

Power supply
The concentration and alkalinity of FIPROSTRIP 287 are maintained by adding, under agitation, FIPROPLUS 910 and FIPROSTRIP 287, in a ratio of 1:1.
Paint residues can be conveniently removed by adequate decantation and subsequent filtration (e.g. with separators and/or filter presses). The solution will thus have a considerably longer service life.
Storage
Tanks for the use of FIPROSTRIP 287 must be made of steel, preferably stainless steel, and be fitted with a closing lid to minimise evaporation losses.
Avoid shocks, improper handling that may result in product spillage.
. Protect from frost, store away from heat sources, keep containers tightly closed.
For more detailed information on handling the product and disposal of solutions, please refer to the safety data sheet.
A neutralisation/degreasing tank, where any paint stripper residue not removed by the first rinse is removed from the workpieces.
Possibility of adding specific cover layer to limit evaporation and possible vapours.
It is used in immersion paint stripping of iron, steel, copper, brass and aluminium parts.
. Before using FIPROSTRIP 286, check the compatibility of the product with the substrate by preliminary testing. Suitable for removing all major synthetic paints except polyurethanes.
The working temperature can range from room temperature up to 50°C.
In order to maintain product properties, the product should be stored at temperatures between 7° C and 30° C.
