Performance Test of Binder
Influence against Humidity with Bending Strength
Test Method
- Three Fulcrums Bending Strength Test:
- distance of fulcrums = 30cm
- binder content of sample = 1%
- circumstance of measurement = room temperature
Test Result
The wax type binder, Celuna P-222, provides and maintains a higher bending strength against moisture content in comparison with PVA type binder.
