Automotive  bottom powder coating

Automotive powder coating are divided into many categories, including automotive engine powder coating, automotive interior powder coating, and automotive bottom powder coating. Today we introduce the automotive bottom powder coating produced by MILESTONE

Car bottom decorations generally do not directly contact sunlight, and these bottom decorations have different performance requirements for powder coatings under different conditions of use.

automotive bottom powder coating need to have good heat resistance and corrosion resistance, and automotive bottom powder coating for shock absorption equipment need to have good toughness and bending resistance.

Epoxy system and polyurethane system are mainly used for automobile bottom powder coating. The technical requirements of automotive bottom powder coating are as follows:

Hardness:                                 2 H

Humidity binding force 240h Adhesion force   2

Milk methyl ethyl ketone wipe type:            The coating does not soften or fall off.

Water resistance 240h/60:                  no blistering, softening or shedding

Heat resistance 16h:                      Unilateral corrosion outside the marking 0.8mm

Humidity resistance 24h:                 Unilateral corrosion outside the marking 0.8mm

CASS salt spray 240h:                         Unilateral corrosion width 3mm

Humidity and heat resistance 1000 h:         no blistering, slight loss of gloss

Resistance to crushed stone impact/level:         4
