What are the performance differences between imported and domestic conformal coatings?
What are the performance differences between imported three anti-paint and domestic conformal coatings?
The sample of an imported brand of conformal coating, Ritop’s UV-9669 conformal coating, 9669-45 conformal coating comparative test. Conduct eight performance tests on high and low temperature resistance, high temperature resistance, low temperature resistance, acid resistance, alkali resistance, salt spray resistance, water boiling resistance, and adhesion, in order to determine the performance advantages and disadvantages of the three sets of conformal coating samples.
SPECIFICATION ITEM | Sub item conclusion (from good to bad) |
High and low temperature resistance | Imported conformal coating ＞ UV-9669 = 9669-45 |
High temperature resistance (cracking) | 9669-45 ＞ UV-9669 ＞ Imported conformal coating |
High temperature resistance (yellowing) | Imported conformal coating ＞ UV-9669 ＞ 9669-45 |
Low temperature resistance | Imported conformal coating = UV-9669 ＞ 9669-45 |
Alkali Resistance | Imported conformal coating = UV-9669 = 9669-45 |
Acid Resistance | Imported conformal coating = 9669-45 ＞ UV-9669 |
Salt spray resistance | 9669-45 ＞ UV-9669 ＞ Imported conformal coating |
Boiling resistance | UV-9669 ＞ 9669-45 ＞ Imported conformal coating |
Adhesion force | Imported conformal coating = 9669-45 ＞ UV-9669 |
Conclusion:
1. The sample of a certain imported brand of conformal coating has better resistance to high and low temperatures, high temperature (yellowing), and adhesion than our company's sample in three aspects;
2. The sample 9669-45 of Ritop’s conformal coating has better high-temperature resistance (cracking), salt spray resistance, water boiling resistance, and adhesion than imported brand samples;
3. The other projects are basically the same;
