Yes. We provide system-specific additive packages—including flow agents, matting agents, dispersants, stabilizers, and degassing agents—optimized for TGIC, HAA, hybrid, metallic, and low-temperature cure formulations.

UV absorbers and HALS additives protect polymer chains from photodegradation, slowing yellowing, chalking, and gloss loss. A tailored combination of UV stabilizers enhances long-term durability for outdoor applications.

Incorrect dosage or low compatibility may lead to craters or fish-eye defects. Degassing agents must be matched with the resin and extrusion profile to allow trapped gases to escape without disrupting surface flow.

Dispersing aids improve pigment wetting and prevent flocculation during extrusion. Without proper additives, the coating may show poor hiding power, color shift, or speckling. Choosing the right dispersant ensures consistent color strength and smooth appearance.

Matting performance depends on resin compatibility, extrusion temperature, particle size of the matting agent, and curing kinetics. Mismatch in these factors can lead to gloss variation. We can help adjust resin–additive ratios and processing parameters to stabilize the finish.

​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.
