Pearlescent pigment application common problems and solutions

Problem general cause solution
Hair flower/pearlescent pigment Spraying too thick or gun distance too close 盹 Improved construction method
Poor orientation, affected by silicones, oils, and formulations or primers
Leveling, defoaming, plasticizer, etc. Cleaning appliances and substrates, improving additives

High boiling point in the diluent, too much solvent
None of the above is the introduction of suitable targeting aids.
Poor cover, the amount of pearlescent pigment is too low, increase to the correct amount / use fine
Particle size pearlescent pigment

The paint is not mixed well before the construction.
Very light-colored pearlescent paint applied to dark pre-coated light-colored primer, combined with fine particle size
Substrate pearlescent pigment or aluminum powder
Too fast settlement, the paint is too thin, and the solid powder of the paint during storage is increased.
Improper selection of anti-settling agent
Severe flocculation/fastening. Poor storage stability of paint. Check the other paint base pigment mixture except pearlescent pigment. Test accordingly and select suitable wetting agent/anti-settling agent.
Thinner mismatch or excessive dilution causes resin to precipitate
Problems with other pigments used
Improper selection of anti-settling agent
Poor pearl effect, paint stability, poor compatibility between components, removal of pearlescent paint, curing reaction
Insufficient pigment dispersion, sufficient wetting of pigments
Inorganic pigment filler excess, changed to the correct method
Poor orientation of pearlescent pigments Improved orientation ("Poor orientation" column)
Pearlescent pigments are dispersed by high shear force and dispersed at a low speed for a long time.
Pelletizing, other pigments, flocculation, coarsening, inspection of paint without pearlescent pigment
The paint base is unstable, causing the precipitation of impurities. Disperse in the correct way.
Pearlescent pigments are not well dispersed. Fully wetted and dispersed pearlescent pigments
Color change Base color change / chromophoric substance Check the paint except the pearlescent pigment
Fading of other pigments
After adding pearlescent pigment, the mechanical properties of the paint film are degraded, and the amount of pearlescent pigment is too large.
Base material has insufficient weather resistance and corrosion resistance.
Color difference between batches of products - base material - color paste - paint, etc. Strict quality control
Accumulation of deviations
