Ripoxy R-804J is a high-performance and widely applicable bisphenol A type epoxy vinyl resin produced by a Japanese company, Showa Denko Co. The following is a systematic introduction of this product:

1. characterization::

   • Excellent chemical resistance: Excellent resistance to acids, alkalis and solvents for chemical equipment manufacturing.
   • high mechanical strength: It has high strength and is suitable for fiberglass reinforced plastics (FRP) and other fields where mechanical properties are required.
   • Excellent fatigue strength and toughness: Excellent durability and toughness for applications where long-term stability is critical.

2. dominance::

   • low viscosity: The resin has low viscosity and is easy to use and process.
   • Fast curing: Shorter curing time helps to increase productivity.
   • Longer shelf life: Has a long storage life for long-term storage and use.
   • fewer bubbles: Fewer bubbles are generated during the curing process, contributing to a high quality finished product.
   • BPO/DMA curing available: Benzoyl peroxide/Dimethylaniline (BPO/DMA) curing systems are available.

3. Application Areas::

   • Chemical industry: Manufacture of chemical equipment such as chemical tanks, pipes, absorbers, ducts, etc.
   • Environmental protection field: lining materials for wastewater treatment systems.
   • Shipbuilding: Manufacture of yachts and ship parts.
   • Construction field: floor lining, waterproof lining and other construction materials.
   • Made of high strength FRP.

4. Performance data::

   • liquid resinAppearance: Clear yellow, viscosity between 2.0 and 3.5 dPa?s/25°C, curing time between 16.0 and 25.0 minutes.
   • Curing resins: Excellent flexural and tensile strengths and heat deflection temperatures for applications requiring high strength and heat resistance.

5. Curing Properties::

   • MEKPO/Co-Oct or BPO/DMA curing systems can be used, with specific curing times varying with temperature and formulation ratios.

6. Precautions for use::

   • For industrial safety and health the presence of styrene needs to be noted and good ventilation and appropriate protective equipment should be worn.
   • Store and handle away from heat or fire to avoid accidents.
   • When using curing agents and accelerators care should be taken to mix them in the correct proportions and to avoid explosive reactions.
