Gelcoats: Ultimate Surface Protection For Composites And FRP Applications

Gel Coat Resins form a 0.4-0.8mm high-performance protective layer on composite surfaces, delivering decorative aesthetics and structural durability for FRP products. Engineered for superior UV resistance, chemical corrosion protection, and >95% gloss retention (ISO 2813), our gel coats enable flawless finishes in marine, construction, and industrial sectors.

Core Technology Advantages
  • Zero Substrate Exposure: Seamlessly blocks fiber print-through and micro-cracks
  • Multi-Process Compatibility: Optimized for spray-up, hand lay-up & vacuum infusion
  • Eco-Compliance: Low styrene emission (<50ppm), REACH & RoHS certified
  • Military-Grade Protection: Salt spray resistance >5,000h (ASTM B117)

Four Gel Coat Types: Targeted Application Matrix
Type Chemical Base Key Advantages Primary Applications
Orthophthalic Gel Coat Phthalic Anhydride + Propylene Glycol Cost-effective, easy application Storage tanks, decorative panels
Isophthalic Gel Coat (ISO Type) Isophthalic Acid + Propylene Glycol Hydrolysis resistance ↑40%, HDT >100°C Ship decks, swimming pools, chemical linings
ISO-NPG Gel Coat Isophthalic Acid + Neopentyl Glycol UV stability (ΔE<2 after 30y), gloss retention >90% Yachts, luxury sanitaryware, wind turbine blades
Vinyl Ester Gel Coat Epoxy Acrylate Acid/alkali resistance (pH 1-14), HDT >130°C Electroplating tanks, FGD scrubbers, nuclear facilities
Selection Protocol
  • Marine Environments: Mandatory ISO-NPG type (DNV-GL/CCS certified)
  • Strong Chemical Exposure: Vinyl ester only (resists hydrofluoric acid)

Validation Notes
  1. Vinyl ester elongation at break >3% (vs. 1.5% for polyester resins)
  2. ISO-NPG retains >92% flexural strength after 5,000h UV accelerated aging

Industrial-Grade Packaging System
Package Type Technical Specification Specialized Use Cases
Standard Drum 20kg galvanized steel + vacuum aluminum liner General-purpose shipping
Pre-Promoted Kit Pre-mixed catalyst, ready-to-use On-site repair & field operations
Arctic Packaging Anti-crystallization agent (-30°C stability) Polar region projects
Explosion-Proof Tote Pressure relief valve + flame-retardant filling Chemical plant transport
Traceability & Safety
  • Laser-Engraved Batch Code: Includes viscosity/gel time/solid content test values
  • Hazard Label: UN 3266 Class 8 Corrosive Liquid (GHS pictograms)

Smart Storage Protocol
Parameter Control Standard IoT Monitoring Critical Response
Temperature 16-30°C Wireless sensors (±0.5°C) >35°C triggers liquid cooling
Humidity ≤80% RH MEMS hygrometer array (±1% RH) >85% RH activates dehumidifier
Vertical Stacking Dedicated racks Tilt sensors (>5° alarm) Auto-lock unstable pallets
Shelf Life 6 months (unopened) ERP auto-lock expired batches Retest viscosity/gel time
Critical Prohibitions
  1. NEVER store with amine hardeners - Causes pre-promoted gel coat failure
  2. BAN silicone-based release agents - Induces fish eyes on surface
