Accelerator Cobalt 1% 0,5 KG
Is a cobalt oxytocopherate accelerator in a dibutylphtalate solution in a 1% solution. This is for the pre-acceleration of polyester resins, vinylester resins, top coats or gel coats. Available in 25 kg and 200 kg containers.

MEKP Catalyst (Methyl Ethyl Ketone Peroxide) is a chemical compound commonly used as a catalyst in the curing of resins, particularly in the production of fiberglass, polyester, and vinyl ester resins. It plays a critical role in initiating the polymerization (curing) process, allowing the resin to harden and form a durable, solid structure.

• Chemical Composition: MEKP is an organic peroxide, composed of methyl ethyl ketone (MEK) and hydrogen peroxide.
• Catalyst Role: It acts as a hardening agent, triggering the polymerization reaction in resins when mixed with the resin and the appropriate accelerator (often a cobalt or amine compound).
• Fast-Acting: MEKP is known for its quick activation time, which allows for rapid curing of resins and is often used in industries where fast production times are needed.
• Temperature Sensitivity: The effectiveness of MEKP is often influenced by the temperature; it works faster at higher temperatures, so the amount of catalyst used may vary depending on the curing conditions.

1. Fiberglass and Composite Materials:
   • Curing Agent for Resins: MEKP is used to cure polyester and vinyl ester resins, which are often used in the manufacture of fiberglass composites. It is a vital component in creating strong and durable fiberglass products such as boat hulls, automotive parts, and construction materials.
2. Polyester Resin Curing:
   • MEKP is commonly mixed with polyester resins for use in manufacturing products like countertops, bathtubs, and adhesives, ensuring that the resin hardens and sets to its final form.
3. Molding and Casting:
   • Used in mold-making, MEKP catalyzes the hardening of resins, helping create detailed and accurate molds for casting materials like metals or plastics.
4. Repair and Restoration:
   • It can be used in the repair of fiberglass structures or in the restoration of damaged surfaces by allowing resins to cure quickly and bond effectively to existing materials.

• Fast Curing Time: MEKP allows for the quick setting of resins, which is advantageous for industries where speed is crucial.
• Strong and Durable Bond: It helps create strong bonds between fiberglass and other materials, ensuring the structural integrity of products.
• Versatility: Can be used in a wide range of applications, including construction, automotive, and boatbuilding.

MEKP is a hazardous material and must be handled with care. Some important safety considerations include:

• Wear Protective Gear: Always wear gloves, goggles, and appropriate clothing when handling MEKP.
• Proper Ventilation: Ensure good ventilation when working with MEKP to avoid inhaling vapors, as they can be irritating to the respiratory system.
• Storage: Store MEKP in a cool, dry place, away from heat, flames, and direct sunlight, as it is a peroxide and can be sensitive to decomposition.

• Mixing Ratio: The amount of MEKP catalyst required depends on the specific resin being used and the desired curing time. The ratio is typically low (about 1-3% of the resin mixture), so it’s important to follow the manufacturer’s instructions for proper mixing to ensure safe and effective curing.
• Pot Life: MEKP affects the pot life (working time) of the resin. If too much is added, the resin may cure too quickly, leading to premature hardening before you can work with it.
