Curing Agent HAA(T105)

Description:

Curing Agent T105 is suitable for the production of outdoor polyester powder coatings. It’s characteristic of low toxicity, no irritant to skin, good weather durability, etc. The chemical structure of T105 is β-hydroxyalkylamide.

Technical data:

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 from 200°C/5min to 150°C/20min; generally, 180°C/15min is preferred.

Suggested Formulation:

Polyester: AV 35mgkoh/g

Packaging:

Available in polyethylene-lined, multi-ply paper bags, N.W. 25KGS/Bag.

Storage and Handling:

T105 is soluble in water; store in closed container, seal the container after operation.
