DYHARD® cure systems

DYHARD® - every day, everywhere

DYHARD® is the brand name for high-performance cure systems based on dicyandiamide hardeners, urone and imidazole accelerators and formulated epoxy resin systems. The DYHARD® product range performs a key role in helping manufacturers to produce high-quality products for demanding applications in a safely manner. They are widely used in the automotive-, aviation industries and in wind power plants. They are also used in the electronic industry and for manufacturing sports equipment.

 

The DYHARD® product range consists of 6 product lines:

DYHARD® CU-Line

Latent curing agents

DYHARD® CAT-Line

Imidazol and uron accelerators

DYHARD® MB-Line

Master batches of curing agents or uron accelerators in epoxy resin

DYHARD® PM-Line

Premixes of curing agents and accelerators

DYHARD® LI-Line

Glass or carbon fabrics are impregnated with a mixture of epoxy resins, hardeners and accelerators. These so-called prepregs are pre-cured and subsequently stored at low temperatures (-18°C). After the prepregs have been cut to size, they are hardened in a mold at temperatures between 100°C and 140°C in an autoclave or press. These types of composites are used in the aviation and automotive industries, in the production of rotor blades for wind power stations and for manufacturing sports equipment such as bicycle frames, tennis rackets and golf clubs.

The crucial requirement for adhesive components is to have a long shelf life even at higher temperatures. This means that the accelerators used in the mixture with epoxy resins, hardeners and fillers must have a very special reactivity profile such as high latency at room temperature and enough reactivity at elevated temperatures.

As adhesives are applied in thin layers, they require stable hardeners with a low particle sizes. DYHARD® hardeners are micronized to a particle size of d98 ≤ 6µm.

The resulting “reactive hot melts”, or single component adhesives, are used as structural adhesives, particularly in the automotive industry, in which they replace conventional technologies such as riveting and welding.

Powder coatings are manufactured from solid resins, pigments and fillers together with hardeners and accelerators. The raw materials are premixed, then melted, dispersed in an extruder and subsequently milled. Powder coatings are applied in a process called electrostatic spray deposition (ESD). This application method uses a spray gun, which applies an electrostatic charge to the powder particles, which are then attracted to the grounded part. The coated part is subsequently hardened in an oven at high temperatures. Powder coatings are very environmentally friendly as they avoid solvents and reduce waste.

The laminates used for printed circuit boards are usually manufactured from glass fiber fabrics which are impregnated with epoxy resins, hardeners and accelerators. The impregnated glass fiber fabrics are dried and pre-cured in hot-air furnaces. Several such pre-impregnated layers are laminated together at high pressure and cured at high temperatures into circuit boards. DYHARD® products can be used to meet FR-4, FR-3, CEM-1 and CEM-3 standards.
