Elecoat UC-4H UV High Hardness Electrodeposition Coating
Elecoat UC-4H UV High Hardness Electrodeposition Coating
Rapidly improved strength for UV coatings and improved chemical resistance
SST and alkali resistance, problems with cation UV, has been greatly improved.
Compared to a conventional product (UC-2000), UV irradiance levels are 25% decreased
