Application:
T105 can be cured with carboxylic polyester. The acid value ranges form 25 to 45 mgkH/g. It is important to select appropriate resin in the formulation to control the possible yellowing phenomena. It is recommended to add certain amount of Degassing Additive (such as Benzoin) to prevent micro-pinholing due to the water produced during the crosslinking reaction of T105 and carboxylic polyester.
Curing condition ranges from200℃/5min to150℃/20min; generally,180℃/15min is preferred.
