Epoxy Adhesives-One Component

One-part epoxies are a premixed adhesive system with base epoxy resin already blended with the appropriate amount of catalyst or hardener that require no mixing and simplify processing. These products are available in liquid, paste and solid forms. Thermal curing, UV light cure and dual UV/heat curing systems are compounded to meet demanding specifications. One part epoxy compositions are designed to eliminate waste, accelerate productivity while alleviating concerns regarding mix ratios, weighing, working life and shelf life. Specially formulated one component epoxy systems feature outstanding performance properties, long-term durability and easy application. These no mix compounds are employed in the electronics, aerospace, medical, electrical, automotive, oil/chemical processing and optical industries. In thermal curing epoxies latent curing agents are blended into epoxy resin single component formula so that shelf-life stability is maintained before heat activation at specified temperature.

Most one-part systems require a temperature of 125°C to 150°C for curing. They fall into three categories based on temperature and curing time: conventional, fast and snap curing. Meanwhile Low temperature heat cure (80°- 100°C) one component epoxy systems are available. For UV light curing epoxies, the reaction is activated by a suitable light source at the proper intensity and wavelength. This type of systems offers fast cure speeds and lower energy consumption.

It must be mentioned that specific grades vary in viscosity, cure speed, chemical resistance and electrical properties, but can be custom formulated to meet your application needs. Our wide range of one component systems can be used for bonding, sealing, coating, potting, encapsulation and impregnation applications. These grades offer:

High temperature resistance
Cryogenic serviceability
Electrical conductivity or insulation
Optical clarity
Thermal conductivity
Flexibility and toughness
High bond strength to similar and dissimilar substrates

Innovations in one-part epoxy adhesives are creating more diverse portfolios, with formulations that cure at lower temperatures for greater flexibility and impact resistance. These innovative chemistries are also more conducive to bonding engineered plastics, leading to applications spanning from consumer electronics to military and aerospace.

FAQ Epoxy Adhesives-One Component

Polyolefin based hot melt adhesives are 100% solid thermoplastic adhesives based on polyolefin polymers such as APAO, polypropylene and related copolymers. They form a bond when heated and develop adhesion as they cool.

They are commonly used for bonding polypropylene, polyethylene, polymer films, nonwoven materials, paper, foils and various industrial substrates.

Depending on the formulation, application temperatures are commonly around 140–190°C. The exact temperature should be selected according to the adhesive grade and application equipment.

Typical applications include packaging, film lamination, nonwoven products, filter assembly, bookbinding, automotive components, textile bonding and general industrial assembly.

Depending on the manufacturer and application, they can be supplied as granules, pellets, blocks, slabs or other hot-melt forms, with packaging commonly selected according to production volume and melting equipment.
