Inspection records support consistency and traceability.

01

INCOMING CONTROL

Raw Material Inspection

Key resins, pigments, fillers and additives are checked before entering production.

  • Supplier and batch verification
  • Appearance and basic properties
  • Key specification confirmation
02

PROCESS CONTROL

In-Process Control

Critical parameters are monitored during mixing, dispersion, grinding, color adjustment and filtration.

  • Mixing and dispersion control
  • Viscosity and fineness checks
  • Color and process consistency
03

RELEASE CONTROL

Finished Product Release

Each finished batch is reviewed against agreed requirements before packaging and shipment.

  • Final specification testing
  • Application panel verification
  • Batch release record

QUALITY CONTROL PROCESS

A Controlled Path from Material to Shipment

Each batch follows defined inspection and release procedures. Test records and retained samples support consistent production and subsequent traceability.

TESTING CENTER & CAPABILITIES

Testing Capabilities for Coating Quality and Performance

Our testing capabilities cover both basic product properties and applied coating performance, helping identify potential issues before commercial production and shipment.

01

Viscosity & Fineness

Evaluation of coating flow, dispersion quality and processing suitability.

02

Solid Content

Confirmation of product composition and consistency within the specified range.

03

Adhesion

Assessment of the bond between the coating film and the selected substrate.

04

Hardness & Abrasion Resistance

Measurement of surface strength and durability under friction or wear.

05

Heat Resistance

Verification of coating stability and appearance under elevated temperatures.

06

Corrosion & Chemical Resistance

Application-based evaluation against corrosive or chemical exposure when required.

Test items and evaluation criteria are selected according to the coating system, substrate and agreed application requirements. External verification can be coordinated when required.

APPLICATION-ORIENTED VALIDATION

Testing Based on Real Application Conditions

Test methods and evaluation criteria are selected according to the coating system, substrate, curing conditions and end-use environment.
