Biresin CH122-1 Hardener (for Biresin CR122 Epoxy Resin)

Brand: Biresin. Category: Chemicals > Adhesives. Biresin CH122-1 hardener is designed for use with Biresin CR122 epoxy resin and ensures fast and reliable curing of composites without the need for additional heat treatment.

Product Description

Biresin CH122-1 is a specialized fast-acting hardener developed for effective cooperation with Biresin CR122 epoxy resin. Thanks to its balanced chemical formula, it provides stable processing properties of the mixture, allowing for high mechanical performance and increased heat resistance of products without additional heating. This makes this hardener an optimal option for serial production, rapid prototyping, and repair work.

Application

Typical areas of application:

• Used in combination with Biresin CR122 to create composite products.
• Optimally suited for fast production processes where time-saving on curing is important.
• Applied in industrial and transport sectors for manufacturing parts from steel, carbon fiber, fiberglass, and other composites.

Advantages

The hardener provides stable processing properties of the mixture, allows for high mechanical performance of finished products, and achieves increased heat resistance without heat treatment. The use of CH122-1 shortens production cycles, reduces energy costs, and increases the overall efficiency of parts manufacturing, which is especially important for serial production and rapid prototyping.

Key Characteristics

Below are the key technical parameters that are important to consider when choosing and using the hardener:

• Pot life: 30 minutes — provides sufficient time for mixing and pouring.
• Mixing ratio: compatible with Biresin CR122 epoxy resin in a 100:30 ratio (by weight).
• Glass transition temperature (Tg): up to 103°C — allows for products with increased thermal stability.
• Advantage: enables rapid manufacturing of parts without the need for heat treatment.

Physical Characteristics (at 25°C)

The manufacturer specifies physical characteristics at 25°C; among them, it is important to consider viscosity and other rheological properties for the pouring and injection process. The provided original description does not specify the viscosity value, so when planning the technological process, it is recommended to clarify this parameter in the technical data sheet or with the supplier.

Usage Recommendations

Before use, thoroughly mix the components in the specified 100:30 ratio by weight, maintain clean tools and molds, and work at the recommended ambient temperature to achieve the stated properties. For best mechanical and thermal properties, follow the technological maps and instructions of the Biresin CR122 resin manufacturer.

Safety and Storage

Work with the hardener should be carried out using personal protective equipment: gloves, safety glasses, and a respirator if ventilation is insufficient. Store in a tightly closed container, away from food products and open flames, at the temperature recommended by the manufacturer. Disposal of residues and packaging must comply with local regulations for handling chemical substances.

If you need precise values of physical parameters or a technical data sheet, please contact a Biresin supplier or distributor of this product for consultation.
