Technology & Formulation Solutions
PCOTEC provides integrated raw-material solutions built on resin engineering, curing-reaction control, additive optimization, and a fully automated production system. With DCS- and PLC-controlled processes, precision dosing, and strict batch consistency management, we deliver stable, repeatable, and performance-validated materials tailored for powder-coating applications.
Resin Engineering
Through DCS-controlled polycondensation, precise acid-value management, molecular-weight design, and consistent melt behavior, PCOTEC supplies a complete range of polyester resin systems:
TGIC-cured polyester resins (outdoor durable / general purpose)
HAA-cured polyester resins (environment-friendly)
Hybrid polyester resins
Specialty resins (silicone resins, matting resins, heat-resistant resins, etc.)
Every batch is monitored for acid value, viscosity, color, and solid content to ensure stability during extrusion, curing, and film formation.
Curing Technology
Our curing-agent platform covers TGIC, HAA, epoxy curing agents, and multiple performance-tailored systems. PLC-controlled reaction steps—neutralization, ring closure, washing, and filtering—ensure:
High reaction completeness
Controlled hydrolyzed-chlorine levels
Stable cure windows
Excellent batch consistency
Additive Optimization
Our additive portfolio includes leveling agents, matting agents, degassing agents, surface-modifying components, gloss-control additives, wax powders, and catalysts.
All additives undergo comprehensive compatibility and application testing:
This ensures predictable performance for formulators and stable appearance control.
Process Stability Engineering
PCOTEC’s production relies on digitalized process control:
DCS reaction control (temperature, pressure, agitation)
PLC safety interlock preventing reaction deviation
MES + LIMS closed-loop data tracing
Precision metering + automatic dosing
This engineering foundation guarantees materials with stable reaction profiles, repeatable melt behavior, and reliable extrusion performance.

Application Testing
PCOTEC conducts application-oriented testing to ensure that resins, curing agents, and additives deliver consistent performance throughout the entire powder-coating process. Our evaluation focuses on curing behavior, surface quality, film integrity, and long-term durability, helping manufacturers validate formulation stability before mass production.
Curing & Crosslinking Performance
PCOTEC evaluates curing behavior through DSC analysis, gel-time measurement, and cure-window verification to ensure stable crosslinking under different oven profiles. Each material is tested for reaction completeness, resistance to over-bake and under-bake conditions, and compatibility between resin and curing agents. This helps guarantee predictable film formation and reliable curing performance in real production environments.
Flow, Leveling & Surface Uniformity
Material flow and surface appearance are examined by observing melt viscosity, extrusion stability, and leveling behavior during curing. In this stage, we closely monitor film uniformity and identify potential defects such as pinholes, craters, shrinkage, or orange peel. By analyzing how resins and additives interact during melting, we help customers achieve smooth, consistent surfaces with minimal appearance variation.
Mechanical & Functional Properties
To confirm coating durability, PCOTEC performs mechanical assessments including impact strength, adhesion, bending resistance, scratch tolerance, and overall hardness. These tests simulate the stress a coating experiences during fabrication, installation, and long-term use. The results allow us to fine-tune resin structures or additive dosages to ensure coatings maintain integrity under real operational conditions.
Durability & Environmental Resistance
For long-term stability evaluation, materials undergo accelerated aging simulations including UV exposure, thermal cycling, humidity conditioning, and salt-spray corrosion. These controlled tests help determine how coatings withstand environmental challenges, ensuring the final system is suitable for outdoor components, industrial equipment, and high-demand protective applications.
