Experimental DSC-based method to determine glass transition temperature during curing of structural adhesives

A new DSC-based experimental method to efficiently establish the glass transition temperature, Tg, vs. curing degree, α, relationship for structural adhesives was developed. The method approaches the continuous Tg-α relationship with a trilinear curve established on the basis of several non-isothermal scans instead of time-consuming isothermal scans. Although the method is independent of the heating rate, a rate of 5 °C/min was found to be the...
