Three Points of Painting Spraying about CNC Prototype
A. The operation of shop primer
1. Before painting spraying, the substrate should be disposed to
no-rust,no oil pollution, and keeping clean.
2. Dedicated diluent should be used to applicable viscosity.
The painting should be used up during 8 hours.
3. One treak of painting is advised and the viscosity should be
15-18s(-4#). The maximum dry film thickness is 25µm.
B. The operation of foundation coat
1. Before painting spraying, the substrate should be disposed
to no-rust,no oil pollution, and keeping clean.
2.Dedicated diluent should be used to applicable viscosity.
The painting should be used up during 8 hours.
3.Two streaks of painting is advised and the maximum dry
film thickness of each streaks is 35±5µm. The operating
interval requires more than 20 minutes.
4. If they need to be polished, the environment temperature
need above 15℃ and proceed after 24 hours drying.
C. The operation of unsaturated polyester putty
1. After completely dry of the primer,the operation of
unsaturated polyester putty can be started.
2. Mixing up the putty in the bucket and deploying the
curing agent. The operation of blade coating can proceed.
3. The first streaks can be 15#. Two streaks can be
