Product Name:Flame RetardantGelcoat HS - LFI7035S
1. Brief Introduction:Introducing HS-LFI7035S Gelcoat, an advanced intumescent flame retardant gel coat. Crafted with isophthalic-adipic acid unsaturated polyester resin, this product ensures superior performance.
Engineered for optimal use in spray processes, it comes pre-promoted and is ideal for the surfaces of FRP products that necessitate flame retardant properties.
.Applications include:
rail transit, wind turbine nacelle covers, ship accessories, and other sectors where flame retardancy is crucial.
2. Features: · Superior construction performance;
· Outstanding flame retardant capabilities (high oxygen index, low smoke density);
· Complies with fire protection standards UIC564-2 Class B
· Excellent water and weather resistance.
3. Gelcoat Properties:
Gel time test: Utilizing Curing Agent M-50 (AKZO) at 2% concentration.
4. Application Notes: 1). Gently mix the gelcoat in its container before use to avoid high shear rates and air entrapment.
2). Optimal application temperature ranges from 18-25°C with humidity below 80%. Ensure the mold is clean and polished before application.
3). The mold surface must be dry, clean, and free from oil.
4). Fully wax the mold surface (avoid silicone-based release waxes). Allow water-soluble release wax to dry completely before gelcoat application.
6). Gelcoat film thickness should range between 600-1000μm. Do not exceed 0.2mm per spray layer. Allow 2-3 minutes for solvent evaporation between layers to achieve desired thickness.
7). Before starting lamination layers, check the gelcoat's cure degree. Press your finger on the gelcoat film for 30 seconds; if no residue remains on your finger while the film remains sticky, proceed with lamination.
5. Operation Procedure:
Note: Use a paint spray can maintaining air pressure at 20psi with air flow not less than 0.6 cubic meters per minute.
1). Follow the application guide requirements for spraying preparation.
2). Apply a thin, easy-to-polish primer layer (thickness below 0.2mm) to the mold surface using a thin layer and multiple passes method. Allow it to evaporate for 2 minutes before spraying the next layer to the desired thickness. The primer will dry within an hour, allowing for sanding to begin.
3). Perform dry sanding using 220-320 mesh sandpaper, then proceed with 600-1200 mesh wet sandpaper. Finish with polishing.
6. Storage:
1) Ensure the product is stored away from any heat sources, including direct sunlight or steam pipes. For optimal longevity, keep it in a dry environment with temperatures maintained below 25ºC.
2) Maintain a tight seal on the container to prevent any moisture absorption and to avoid monomer evaporation. Storing the product beyond the recommended conditions can affect its liquid resin properties, such as viscosity and gel time.
3) During transportation, comply with the State Council's 'Chemistry Dangerous Articles Safety Management Regulations.' As the product contains styrene monomer, it is classified as hazardous and flammable.
