Why GOMIN
Six Pillars of Performance
Engineered for production environments where compatibility, consistency, and longevity are non-negotiable.
Zero Resin Content
No resin binders means no compatibility clashes. A single paste grades across waterborne, solvent-based, and specialist resin systems.
Nano-Ground Dispersion
A tandem coarse-then-fine grinding process achieves sub-micron particle uniformity. The result: exceptional gloss, transparency, and zero settling or flooding.
Superior Weatherfastness
Lightfastness grades 7–8 and weatherfastness grades 4–5 ensure colour stability through outdoor exposure exceeding five years — no fading, no chalking.
High-Temperature Stability
Selected grades withstand stoving and baking from 200°C to 280°C without colour shift — critical for automotive components, hardware, and electronics coatings.
Full Colour Range
Carbon black, titanium white, organic yellow, red, ultramarine, phthalo blue & green, and permanent violet. Custom PANTONE and RAL matching available on request.
Washable-Coating Clean
No resin residue after washing — making GOMIN paste the preferred choice for children's toy lacquers, medical device coatings, and washable architectural finishes.

Application Areas
From architectural exteriors to precision electronics, GOMIN colour paste delivers consistent performance across demanding sectors.
Construction & Architecture
Exterior wall coatings, floor epoxy, bridge anti-corrosion systems. Long-term UV and weathering resistance critical.
Automotive & Stoving
Automotive component coatings, hardware baking finishes. Formulated for colour stability through 70–280°C cure cycles.
Electronics & 3C
Smartphone casings, peripheral devices, precision electronics. Requires food-grade cleanliness in mixing equipment.
Toys & Medical Devices
Washable coatings for children's products and medical surfaces. Zero resin residue guarantees post-wash purity.
Furniture & Flooring
Wood lacquer tinting, stain base, and floor coating systems. Exceptional transparency and gloss enhancement.
Industrial Equipment
Machinery coatings, plastic-substrate finishes, and industrial re-coating projects demanding chemical resistance.
Technical Questions
Common formulation and application questions — answered by our technical team.
What does "resin-free" mean for compatibility?
Conventional colour pastes contain a resin binder that must match the host coating's chemistry. GOMIN's resin-free formula eliminates that constraint entirely — the paste integrates into acrylic, epoxy, alkyd, polyurethane, fluorocarbon, and polysiloxane systems without reformulation or compatibility testing beyond a standard 1–2% tint trial.
How should I disperse GOMIN colour paste into my coating?
Stir the paste for 5–10 minutes before use to ensure no sedimentation. Add paste slowly at the vortex edge of the mixing vessel — primary shade first, secondaries after. For waterborne systems, disperse at 800–1200 rpm for 10–15 minutes; for solvent-based, 600–1000 rpm for 8–12 minutes. Filter through 150–250 mesh before application.
Can I use GOMIN paste in UV-curable coatings?
Yes. GOMIN's resin-free formulation is compatible with UV-curable (photo-curable) resin systems. Dalian Gomin Special Coating is a specialist UV coating manufacturer, and the paste range is specifically engineered with UV chemistry in mind. Conduct a curing performance check at your exact UV dose and initiator loading before full production.
What is the shelf life and storage condition?
Unopened: 24 months stored at 0–35°C, away from direct light, moisture, and ignition sources. Opened: use within 3 months. Mild sedimentation after prolonged storage is normal — thorough stirring restores performance fully.
Can water-based and solvent-based colour pastes be mixed?
No. Mixing waterborne and solvent-based colour pastes will cause emulsion breakdown and ruin the batch. Keep dedicated tools for each system type and label containers clearly to prevent cross-contamination.
