Explore our high-performance tapes, sleeves, and fillers engineered to match the sealing and structural reinforcement standards of leading global pipelines.
The industrial shift towards 100% solids technologies to eliminate VOCs, mitigate cathodic disbondment, and guarantee heavy-duty protection.
Global environmental bodies such as the EPA and REACH have enforced stringent restrictions on volatile organic compounds (VOCs). Traditional solvent-borne primers release harmful emissions during film consolidation, leaving dry paths or micro-voids in the coating matrix. Our solvent-free epoxy primer formulations are 100% solids, eliminating solvent evaporation, avoiding pinholes, and ensuring absolute environmental safety.
Since solvent-free liquid epoxies do not shrink during curing, you achieve direct equivalent dry film thickness (DFT) from wet film thickness (WFT). High-build attributes allow structural components to receive extensive mechanical and corrosion barriers in a single pass. This improves application throughput for steel pipe operations, marine piles, and joint protection projects.
By using low molecular weight epoxy resins paired with amine adduct hardeners, the primer wets and penetrates metal surfaces. It establishes structural mechanical anchors and polar covalent bonds with blasted steel substrates (minimum SSPC-SP 10 / ISO Sa 2.5). This layer serves as the primary barrier preventing oxygen, water, and ions from initiating localized corrosion cells.
| Performance Standard Parameters | Typical Solvent-Free Epoxy Primer | Conventional Solvent-Borne Epoxy | Technical Advantage Realized |
|---|---|---|---|
| Solid Volume Density | 100% (Solvent-free) | 50% - 65% | Zero shrinkage, void-free continuous barrier matrix. |
| Cathodic Disbondment (ASTM G8, 28 Days) | < 5 mm radius at 20°C | 12 mm to 20 mm radius | High resistance to electrical current stress under cathodic protection. |
| Adhesion Pull-Off Strength (ASTM D4541) | > 18 MPa (Concrete & Steel) | 8 - 12 MPa | Excellent interfacial bond strength preventing delamination. |
| Volatile Organic Compounds (VOC) | < 10 g/L (Ultra-low) | > 350 g/L | Compliance with worldwide health and safety laws. |
CYCT New Materials: Pioneering Anti-Corrosion Research and National CNAS Laboratory Testing Capabilities
Year of Establishment
Nationally Accredited Laboratory
Active Corporate Member
Supplier to PetroChina, Sinopec, & PipeChina
CYCT New Materials Company Limited (for short, CYCT) is a state-level high-tech enterprise integrating R&D, production, and sales of pipeline corrosion protection materials as well as buried pipeline detection service and pipeline coating field application service into one. Established in the year 2000, CYCT has dedicated itself to the research, advancement, and manufacturing of premier corrosion prevention products for decades. We own leading testing and R&D capabilities, supported by a professional technical team and a national CNAS-accredited laboratory.
Over the years, CYCT has built a reputation as a stable supplier of field joint coatings in major pipeline grids. We operate in close partnership with heavy industry operators including PetroChina, Sinopec, PipeChina, China Gas Group, and Indian Oil, ensuring local pipeline safety. Beyond traditional liquid systems, CYCT has successfully developed specialty corrosion protection materials, such as visco-elastic anticorrosion materials, special photo-curing sleeves for HDD protection, and advanced polyurea coatings.
By cooperating with research institutions such as the CNPC Pipeline Science Research Institute, CYCT provides in-service pipelines with varied technical services. These include buried pipeline detection, custom design schemes, cathodic protection integration, rehabilitation projects, and complete safety protection systems. This positions us as a trusted partner for global OEM and ODM sourcing demands.
Providing specialized anti-corrosion barriers for challenging infrastructure conditions worldwide.
Mainlines require durable field joint coatings. Our solvent-free epoxy primer works as the primary adhesion promoter on bare steel joints before installing heat shrinkable sleeves. This ensures a tight, moisture-proof seal across hundreds of miles of pipeline.
HDD operations subject pipeline coatings to severe shear stresses and rock impacts. Our liquid epoxy primers cure into a highly cross-linked polymer network, providing the mechanical resistance needed when pulled through borehole paths.
Offshore structural steel, dock piles, and riser lines face continuous exposure to salt water, wind, and waves. CYCT's solvent-free chemistry cures in humid marine environments, preventing under-film corrosion even when exposed to high chloride levels.
Adapting to new materials and chemical innovations to meet changing performance requirements.
Future iterations of CYCT's solvent-free primer incorporate nanosized graphene plates and specialized ceramic beads. These additives create a longer path for moisture, oxygen, and corrosive ions, improving the lifetime of the coating barrier.
We are researching microencapsulated corrosion inhibitors integrated directly into the liquid epoxy formula. If mechanical damage occurs, the microcapsules rupture, releasing healing agents that react with the substrate to seal the scratch and prevent corrosion spread.
A Council Member of the Chinese Society for Corrosion and Protection (CSCP) and high-tech enterprise.
CYCT holds multiple industry credentials, including the Qualification Certificate of Corrosion Protection Construction, the Qualification Certificate of Pipeline Detection, and recognition as a well-known brand of Pipeline Corrosion Protection in China. Our operations conform to international ISO standards, and our products undergo qualification tests to verify their performance under harsh field conditions.
A production environment designed to maintain reliable batches and high output capacities.
Our facility uses automated raw material feed lines, temperature-controlled chemical reactors, and multi-stage filtration units. By managing critical parameters, CYCT ensures each batch of solvent-free epoxy primer meets density, viscosity, and cure profile specifications. We trace and test raw materials from receipt through final packaging to guarantee product consistency.
