Product Name:Epoxy Vinyl Ester Resin HS-4430
1. Brief Introduction:HS-4430 is a high-performance bisphenol A epoxy vinyl ester resin, perfectly engineered for producing various FRP applications such as anti-corrosive linings, FRP tanks, electrical insulating materials, and FRP molds. Designed for hand lay-up, pultrusion, and filament winding processes, HS-4430 showcases superior mechanical strength, remarkable toughness, and exceptional heat and corrosion resistance. It stands as one of the pinnacle resins crafted specifically for the marine industry.
premium resins ever designed for the marine industry.
2. Technical Data Sheet for Liquid Resin:
Curing system in GT test: Accelerator 0.6Co/Naph: 2%; Hardener AKZO LPT: 2%;
3. Physical properties of casting (for reference only):
Note:
1) The casting is made according to GB/T8237-2005; Curing System: Accelerator KC: 1.0%;
Hardener AKZO LPT: 1.0%;
2) Post curing: RT×24hrs +80ºC×24hrs;
4 . Instruction and attention:1) To minimize bubbles and achieve an extensive gel time range, utilize a low-activity curing agent like Butanox LPT from AKZO. When applying as an overcoat layer (such as the outermost layer of pipelines and tanks), paraffin must be added to ensure optimal curing.
When used as overcoat layer (such an the outermost layer of pipeline and tank), paraffin must be added to ensure the expected curing degree.
2) The recommended addition is 300ppm (melting point 52~57ºC). To maximize the benefits of paraffin, the resin should have a short gel time (about 30 minutes).
3)In order to reduce the bubble and achieve a broad gel time scale, curing agent with lowactivity such as Butanox LPT produced by AKZO. When used as overcoat layer (such an the outermost layer of pipeline and tank), paraffin must be added to ensure the expected curing degree. The recommended addition is300ppm (melting point 52~57ºC). At the same time, in order to employ the paraffin to the best advantage, the resin should have a short gel time (about 30 minutes).
5. Storage:
1) Avoid exposure to heat sources such as direct sunlight or steam pipes. Store in a dry place at temperatures below 25ºC.
2) Keep sealed to prevent moisture absorption and monomer loss. Prolonged storage outside recommended conditions may affect liquid resin properties like viscosity and gel time.
3) Transportation should comply with the State Council 'Chemistry Dangerous Articles Safety Management Regulations'. As it contains styrene monomer, it is both hazardous and flammable.
