​Flow modifiers and leveling agents control melt viscosity and surface tension during curing. The correct additive selection prevents defects such as orange peel, craters, and pinholes while ensuring a smooth, uniform finish.

​Curing agents determine the crosslinking speed and melt viscosity during the curing stage. If the reactivity is too fast, the coating may gel prematurely, causing orange peel or poor leveling. If too slow, the film may sag or show surface defects.

Absolutely. We provide recommended stoichiometric ratios, reaction-kinetics support, and resin–curing-agent matching to ensure stable processing at your target line speed and oven temperature.

Curing-agent structure directly influences thermal stability and UV performance. We design and select curing agents with optimized crosslink architecture to minimize yellowing and improve outdoor durability.

Temperature, humidity, and inhibitor effectiveness play major roles in resin shelf life. High temperatures may cause premature crosslinking, viscosity increase, or accelerated aging. Moisture can trigger hydrolysis in certain polyester systems or reduce flow.

Yes. We offer curing agents with different activation energies, allowing formulations to cure at conventional 180–200°C or energy-saving 140–160°C depending on application needs.

Our team can evaluate curing-agent reactivity, resin compatibility, cure-window design, and oven parameters to optimize the formulation and ensure full crosslinking.

We control purity, particle size, and reaction-endpoint parameters during synthesis, and test each batch for reactivity index to ensure predictable curing behavior in TGIC and HAA systems.

We offer resin selection recommendations, pigment/additive compatibility checks, sample extrusion testing, and application validation to ensure reliable, scalable production.

Yes, we can tailor TGIC/HAA cure kinetics, adjust resin reactivity, and provide formulation guidance to match your oven temperature, line speed, and product requirements.

We design polyester backbones with UV-stable structures, controlled MW distribution, and optimized end-group chemistry to enhance gloss retention and anti-yellowing performance.

​Our technical team can analyze resin melt behavior, additive compatibility, and extrusion conditions to recommend an optimized resin grade or adjustment to improve surface appearance.
