Cationic vs Free Radical Reaction: Epoxies and Acrylate UV Cure Adhesives

Free-Radical Curing Mechanism Used for: Acrylates, methacrylates, unsaturated polyesters, styrenics, vinyl monomers. Initiation:Free-radical initiators (e.g., peroxides, azo compounds, or UV photoinitiators) generate radicals under heat or light.Example: R−O−O−R→ 2R⋅R-O-O-R  Propagation:The radical adds to a vinyl group (C=C), creating a growing chain radical. R⋅+CH2=CHX→R−CH2−CHX⋅R Termination:Two radicals combine or disproportionate, stopping growth. R⋅+R⋅→R−RR Very fast polymerization. Works with a wide variety of monomers. Common in UV-cure adhesives and 3D printing resins. Limitations:…

Different Types of Structural Adhesives

Structural adhesives are specially formulated polymers designed to hold load-bearing parts together in engineering, construction, and manufacturing. Unlike temporary or light-duty adhesives, structural adhesives form permanent, high-strength bonds that can withstand mechanical stress, temperature changes, and environmental exposure. They are widely used in aerospace, automotive, electronics, construction, and renewable energy industries because they often outperform traditional fastening methods like screws, bolts, and welding. There are several types of structural adhesives,…

Thermally Conductive Adhesives

Thermally conductive adhesives (TCAs) are specialty bonding materials that both mechanically secure components and provide a heat‐flow path between heat‐generating devices (e.g. power semiconductors, LEDs, batteries) and heat‐dissipating structures (e.g. heat sinks, chassis). They’re widely used in electronics, EV battery packs, LED modules, and aerospace systems to prevent overheating, improve reliability, and even replace mechanical fasteners. 1. Key Functions & Formats Primary roles Thermal management: fill micro-gaps and conduct heat…

How To Choose the Proper Potting Compound: 3 Common Chemistries Explained

What To Consider Before Choosing a Potting Compound Choosing the proper potting compound is critical to protecting electronic assemblies, motors, sensors, and power modules. The right material must handle heat, vibration, moisture, and chemicals while fitting your production process and cost targets. Most potting and encapsulating applications use one of three chemistries: epoxy, urethane, or silicone. Each offers different levels of mechanical strength, flexibility, temperature resistance, and processability. In this…

Active Alignment Adhesives

What is active alignment? Active alignment refers to the process of fine-tuning or precisely aligning components, typically optical or mechanical systems, while the system is actively operating. This method is commonly used in the manufacturing and assembly of high-precision devices, such as cameras, sensors, and optical instruments. In contrast to "passive alignment," where components are assembled based on predetermined measurements or templates, active alignment adjusts the components in real-time while…

Advantages of UV Cure Epoxy

Cationic epoxy, more commonly UV cure epoxy, refers to a type of epoxy resin system that cures through a cationic (positively charged) polymerization mechanism. Epoxy resins are polymers widely used in various industrial applications, including adhesives, coatings, and composites, due to their excellent adhesive properties, chemical resistance, and mechanical strength. In a cationic epoxy system, the curing process involves the reaction of epoxy groups (usually present in the resin) with…
