AHA6310

Description

AHA6310 is a phenolic hydroxyl group terminated resinous curing agent for functional and
decorative epoxy powder coatings. It, in combination with solid bisphenol-A epoxy and/or
epoxy novolacs, provides the excellent chemical resistance and mechanical properties,
therefore recommended to use in application of bulk package, fittings, pipeline, rebar, tap
and value etc. It contains no accelerator.

Typical physical data

Application

AHA6310 is recommended to use mainly in the functional epoxy powder coatings for the protection of bulk package, fittings, pipeline, rebar, tap etc.

Advantages:

• Quite high softening point & less powder blacking /sinter tendency
• Excellent flexibility & mechanical properties
• Excellent chemical & cathode delaminating resistance
• Wide range of formulating altitude due to unnecessary of exact stoichiometric ratio of curing agent against resin binder
• Wide range of curing schedule
• Excellent edge coverage
• No frozen supply chain, Excellent storage stability

Use levels & Processing

Use level is mainly determined empirically but unnecessary to very exact. Approx. 22-28 parts against 100 parts of 3 type epoxy resin [EEW560-750] by weight recommended. In order to improve cathode delaminating resistance less than 5-20% of use level on stoichiometric ratio of curing agent against epoxy binder will be possible to acceptable when 2-methyl imidazole added as accelerator.
AHA 6310 is added to the binder/pigment blend before extrusion.
Imidazole accelerator addition in powder formulation required for initiating the reaction phenolic hydroxyl with oxiranyl group
