Emission factors for core-making

Emissions for the cold-setting processes can be described as follows  

Phenolic Vapours of formaldehyde and phenol may be emitted because of the vapour pressure of these constituents. But, as the polymerisation occurs at ambient temperature, these vapour pressures are low and given the consumption rates, the emissions are insignificant 

Resol-ester The resin contains unreacted phenol and formaldehyde, but their emissions are extremely low and environmentally insignificant
