Corrosion Resistance Test (*2) | No corrosion | No corrosion | No corrosion |
(*1) | The test procedure for cross-cut adhesion is as follows: Using a safety razor, create a mesh of intersecting cuts (the shape of lines on a Checker board) into a base material that has been coated with SUMIKAEXCEL 5003P. The cuts must be deep enough to reach the base material and should be spaced 1 mm apart, to form a series of 1 mm x 1 mm squares, over an area of 100 mm2. Place adhesive tape over the area of the cuts and apply pressure, then remove the tape. Check the squares to determine the number of squares that still contain the PES coating. |
(*2) | The test procedure for corrosion resistance is as follows: Place several drops of a solution containing 15% (vol) nitric acid onto the test surface that has been coated with SUMIKAEXCEL 5003P. Cover the surface with a glass plate and let it stand for 24 hours. Observe any changes in the surface appearance. |

(Note) | 1)G1c values were measured under flat surface distortion conditions at -65°C. 2) Tg values were measured using torsion DMA. |
The table above indicates a large increase in fracture toughness (G1c). It is also apparent that Tg does not decrease as significantly. |
