This explains the minimal shrinkage from the acrylic epoxy binder that contains lower solvent levels than PUCB binders.
The standard PUCB binder tested used a moderate to low volatility solvent, which may have slowed the shrinkage under the different conditions.
PUCB systems lose strength and stiffness quickly with moderate to high increases in temperature.
Similar to the PUCB, the EACB had a linear relationship between the tensile strength and the modulus of the samples tested at elevated temperatures.
In the PUCB bonded samples, both RIO and BIO showed contraction after peak expansion, but this contraction seemed to be delayed by 400F (204C).
The interaction of PUCB binder's core production properties vs.
Other variables in the core manufacturing process can interact with the PUCB binder's properties and affect the core and casting quality.
But compared to SPM, PSC requires more PUCB core machine capacity, which is less expensive than automated dies or carousels.
When producing castings in green sand with PUCB cores, the core binder decomposes and releases the core sand into the green sand system.
To keep up with new PUCB binders, test methods have been developed that accurately measure binder reactivity and amine consumption efficiency.
PUCB cores made from silica sand have the tendency to produce casting defects due to hot distortion errors.
