In the world of resin curing, striking the right balance between curing time and achieving desired material properties is crucial. At Hengqi, we understand this delicate balance, which is why we offer medium-temperature curing agents like our methyl ethyl ketone peroxide mixture (Compound OT). These agents provide a sweet spot, allowing for shorter curing times while maintaining excellent performance in the final product.

 What is Medium-Temperature Curing?

Medium-temperature curing refers to curing processes that occur at temperatures typically between 80°C and 120°C (approximately 176°F to 248°F). This range offers several advantages over room-temperature or high-temperature curing methods:

   Faster Curing Times: Compared to room-temperature curing, medium-temperature curing significantly accelerates the reaction, reducing production time and increasing throughput.

   Improved Properties: The increased temperature facilitates a more complete and uniform cure, leading to enhanced mechanical properties, chemical resistance, and thermal stability in the final product.

   Energy Efficiency: Medium-temperature curing requires less energy than high-temperature processes, resulting in lower energy consumption and reduced production costs.

 Benefits of Medium Temperature Curing Agents

 Good Storage Life: Many medium-temperature curing agents have the ability to have a good room-temperature storage life.

   Shorter Curing Times: Phenalkamines exhibit fast reactivity with epoxy resins, allowing for quick curing times and the ability to achieve high degrees of cure in a relatively short period.

   Enhance Resin Performance: These curing agents provide shorter cure times, optimal properties, and reduce energy consumption.

   Meet Requirements: Medium-temperature curing agents have domestic application requirements, and can meet preparation periods in the fields of airplanes, automobile parts, medical equipment, and spaceships.

 Hengqi's Medium-Temperature Curing Solution: Compound OT

Our Compound OT (methyl ethyl ketone peroxide mixture) is a prime example of a high-performance medium-temperature curing agent designed for specific applications. This mixture of organic peroxide polymers and multimers, enhanced with anti-cracking agents and other additives, offers several key advantages:

   Safe and Reliable: The carefully balanced formulation ensures safe handling and storage while minimizing the risk of cracking or deformation in the final product.

   Excellent Curing Performance: Compound OT promotes efficient curing at the recommended temperature range (80-105°C), resulting in products with superior mechanical properties and durability.

   Application Specific: This product is designed for use in medium-temperature curing processes for artificial quartz stone, countertops, sanitary ware, and other similar products.

 How to Use Compound OT

To achieve optimal results with our Compound OT curing agent, follow these guidelines:

1.  Dosage: The recommended addition amount is 0.8-1.5% by weight of resin, but always refer to your experimental data for fine-tuning.

2.  Mixing: Add additives and color paste to the resin and stir thoroughly. Then, add Compound OT and stir well, followed by the powder. Keep stirring time below 3 minutes.

3.  Curing: Allow the mixture to cure at 80-105°C.

4.  Processing: The mixture is suitable for processing within 3 hours, with pressing finished within 1.5-3 hours.

 Safety and Storage

Handling and storing medium-temperature curing agents requires careful attention to safety precautions:

   Avoid Contact with Incompatible Materials: Strictly prohibit contact with heat sources, fire, metal, metal rust, strong oxidizing agents, acids, reducing agents (accelerators), and flammable substances.

   Proper Ventilation: Ensure the storage room has good ventilation.

   Temperature Control: Maintain a storage temperature below 25°C. Consider using a water bath to help regulate temperature.

   Protective Equipment: Wear a gas mask, goggles, rubber gloves, and other protective equipment during operation.

   First Aid: In case of skin contact, wash the affected area immediately with water and washing powder for at least 15 minutes. Seek medical attention if necessary.
