Standards & Certifications
Industrial paints and corrosion-protection coatings designed per ISO 12944 (Parts 1-9, atmospheric corrosivity C1-C5 + immersion Im1-Im3) — the global standard cited in Thai government TOR and MNC projects. Dry film thickness (DFT) measured per SSPC-PA 2 + ISO 19840. Adhesion tested per ASTM D4541 (pull-off, >5 MPa for epoxy primer). Cure time and salt-spray resistance validated per ASTM B117 (>1,000 hours for marine grade). Surface prep per SSPC-SP 6 (commercial blast) or SP 10 (near-white) as specified. Saha industrial coating system — 1-part moisture-curing PU primer / 2-part solvent-free epoxy / 2-part water-based luminous polyurethane / acrylic-silicate antimicrobial concrete sealer — meets VOC compliance + EPA REACH + TIS industrial paint standards.

01Photoluminescent Coating (Water-based 2K Polyurethane)
Safety Coating — Emergency Egress & Wayfinding
Photoluminescent Coating (Water-based 2K Polyurethane)
Safety Coating — Emergency Egress & Wayfinding
Purpose & best fit
Water-based photoluminescent coating that absorbs light (sunlight, fluorescent, or ambient) and emits it in darkness without external power. Used for emergency egress signage, road edges, parking columns.
Working principle
Photoluminescent pigment (typically strontium aluminate) absorbs photons → electrons jump to excited state → slowly release as visible light in darkness via phosphorescence. Not radioactive, not battery-powered.
Specifications
- System
- 2K water-based polyurethane
- Glow Duration
- 8–12 ชั่วโมง / hours ในที่มืด
- Service Life
- ≥ 1 ปี / year (กลางแจ้ง outdoor)
- Coverage
- 1 kg / 5 m² (1 coat), 1 kg / 2.5 m² (2 coats)
- Colors
- เขียวอมเหลือง, เขียวอมฟ้า / Yellow-Green, Blue-Green
Real-world applications
- Building emergency egress paths, exit signs
- Road shoulders, unlit road edges
- Parking garages, support columns, parking-bay markings
- Warehouse/factory aisles for emergency wayfinding
- Stair-tread edges in high-rises
Benefits & outcomes
- No electricity — keeps working during power failure
- No radioactive material — safer than tritium signage
- Water-based — indoor-safe, low VOC
- Apply over existing paint — easy retrofit

02Anti-Microbial Acrylic-Silicate Concrete Coating
Specialty Coating — Concrete Hardening + Antimicrobial
Anti-Microbial Acrylic-Silicate Concrete Coating
Specialty Coating — Concrete Hardening + Antimicrobial
Purpose & best fit
Water-based acrylic-silicate (≥ 10%) concrete surface treatment that simultaneously hardens the surface 3–5× and prevents fungal/algal colonisation for 3–5 years.
Working principle
Silicate reacts with free lime (Ca(OH)₂) in concrete to form dense calcium silicate hydrate (C-S-H) → pore-fills the surface, reduces water absorption. Acrylic polymer creates a clear hard inorganic film that resists spore adhesion.
Specifications
- System
- Water-based acrylic polymer + silicate (≥ 10%)
- Service Life
- ป้องกัน fungal/algae ≥ 3–5 ปี / years
- Hardness Gain
- 3–5 เท่าของผิวคอนกรีตเดิม / 3–5× original surface
- Color
- ขาวขุ่น, ขาว / Milky white, white (เคลือบ clear film)
- Efflorescence
- ป้องกันคราบเกลือขาว / Prevents salt blooms
Real-world applications
- Factory concrete floors with foot/forklift traffic
- Hospital and commercial-kitchen concrete walls
- Food-grade warehouse floors requiring dust-free surfaces
- Parking lots, outdoor concrete plazas
- Public restrooms vulnerable to mould
Benefits & outcomes
- 3–5× harder surface — resists forklift and foot-traffic abrasion
- Dust-free, stain-resistant — reduces re-coating frequency
- Prevents mould/algae growth for 3–5 years — cuts cleaning labour
- Stops efflorescence (white salt blooms) common in new concrete
- Industrial-grade chemical resistance

Holiday / Pinhole Detection in Coatings — Wet Sponge vs High-Voltage Spark per NACE/AMPP SP0188 & ASTM D5162
A guide to detecting holidays/pinholes (invisible discontinuities) in protective coating films: choosing low-voltage wet sponge (thin film < 500 µm) vs high-voltage spark/DC (thick film > 500 µm) per NACE/AMPP SP0188, SP0490 and ASTM D5162 — setting voltage by DFT (too low misses holidays, too high burns the film), which work requires it (tanks/pipes/immersion/marine), mark-repair-retest, and what a TOR must specify.
