■ Application

T105 can be cured with carboxylic polyester. The acid value ranges from 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 from 200℃/5min to 150℃/20min; generally, 180℃/15min is preferred. Suggested Formulation:
