resin coatd aluminium paste
what is different between 3C aluminium paste with traditional aluminium paste ?
what is 3C , 3C goods is like our mobile phone , our home appliances ,computers.
what is request for aluminium paste ?
it is should be smoothly aluminium paste with tidy array , the aluminium frame should be structure . normally we offer client is 8-18um
Grade | Non volatile Content (%±2) | specific gravity approx g/cm3 | Particle Size Distribution D50（±2μm） | Solvent | package |
C11 | 62 | 11 | polymer resin | MS/SN | 20KG/DRUM |
C13 | 62 | 13 | polymer resin | MS/SN | 20KG/DRUM |
C16 | 62 | 16 | polymer resin | MS/SN | 20KG/DRUM |
C18 | 62 | 18 | polymer resin | MS/SN | 20KG/DRUM |
C8 | 62 | 8 | polymer resin | MS/SN | 15KG/DRUM |
we have black glossy type and white glossy type
from the phofo we can see the traditional aluminium paste is silver dollars shape , but it is have small flake and fragment flake .
however resin coated aluminium paste, it is tidy silver dollars , very uniform .
however , we are aslo check from particle size , for same particle size like 11um , the narrow span means size is more uniform。
we will be aslo test from panels to checking metallic feeling .
some clients is request resin coated aluminium paste should be resistance chemicals .
at this time we should be coated aluminium paste by macromoleule. so that have compact protect surface , we are still suggest our 8-18um silver dollars shape .
how we test for resistance chemicals aluminium paste ?
first , the particle size , glossy , solid is must to be tested .
second , we will be use 10%aluminium paste spary to basic on ABS panels , do resistance voltage test , the result should be more than 5000v.
during test acid base , we will be put to 5% NAOH2 , will be soak around 24hours .
we will be found the traditional aluminium paste surface aluminium paint will be fall off , but the resin coated aluminium paste will no changed .
how we can let our aluminium paste get it ?
we will be coated by si02 , it is hydraulic , have protect for aluminium flake , it is steady in teh water , the surface coated is 20-40nm
