TABLE 1
| Sample (I) | Water contact angle | Oil contact angle | Adhesion of paint film | Hardness of paint film | Formaldehyde emission |
| Example 1 | 124 | 89° | 0-1 stage | 5H | 0.11mg/L |
| Example 2 | 121° | 83° | 0-1 stage | 3H | 0.18mg/L |
| Example 3 | 120° | 84° | 0-1 stage | 3H | 0.15mg/L |
| Example 4 | 123° | 86° | 0-1 stage | 3H | 0.14mg/L |
| Example 5 | 92° | 72° | 0-1 stage | 2H | 0.20mg/L |
| Example 6 | 103 | 71 | Grade 0-1 | 3H | 0.25mg/L |
| Example 7 | 98 | 76 | 0-1 stage | 3H | 0.22mg/L |
| Comparative example 1 | 63° | 30° | / | / | 0.32mg/L |
| Comparative example 2 | 85° | 45° | 0-1 stage | 3H | 0.30mg/L |
| Comparative example 3 | 90° | 63° | 0-1 stage | 2H | 0.28mg/L |
As can be seen from Table 1, in comparative example 2, due to the lack of fluorine-containing monomers in the coating, macromolecular chains with fluorine-silicon bonds cannot be formed, so that the surface energy of the coating is relatively high, the hydrophobic and oleophobic properties are weak, and the sealing and insulating capability to formaldehyde is weak; comparative example 3 was not cured thermally, so that the topcoat modifier, fluoromonomer, did not accumulate much on the coating surface, and also resulted in a coating with poor water and oil transport properties, blocking and barrier properties to formaldehyde.
Examples 6 and 7 contained only one photoinitiator and the coatings were UV cured only once, making the coating surface smooth relative to examples 1-4, difficult to form micro-wrinkles, resulting in relatively poor anti-fingerprint properties.
