Transformer coils and inductors generate heat during operation, are subject to vibration, and are exposed to moisture and mechanical stress. Potting these components is critical for insulation, thermal management, vibration damping, and long service life. Why Do Transformers and Inductors Require Potting? Moisture accumulation and corrosion between winding conductors Winding insulation degradation from vibration fatigue […]

Moisture and Water in Cable Insulation: Long-Term Risks
Moisture ingress in electrical cable connections may not cause immediate failure — but over time it seriously threatens insulation integrity, conductor condition, and system safety. How Does Moisture Damage Cable Insulation? 1. Corrosion at Conductor Surfaces Moisture causes oxidation and corrosion at copper or aluminium surfaces. The oxide layer increases contact resistance → heating, transmission […]
What Is NCflex? Elastic Re-Enterable Insulation Resin
NCflex PBD W-25 is a two-component elastic insulation resin based on polybutadiene (PBD) chemistry. Unlike rigid polyurethane or epoxy systems, NCflex does not form a hard structure after curing. Instead, it produces a low-modulus, elastic, and hand-removable protective mass. NCflex vs Rigid Polyurethane Criterion NCflex Rigid PU System Cured structure Elastic, low-modulus Hard, rigid Service […]
IP67 and IP68 Explained: Electrical Insulation Protection Ratings
Technical Guide IP67 and IP68 Explained: Electrical Insulation Protection Ratings IP67 and IP68 are among the most frequently referenced protection ratings in electrical insulation, cable joint protection and junction box encapsulation. Understanding the difference between these ratings is important when selecting the right potting resin, re-enterable insulation system or silicone gel solution for field applications. […]
Insulation Resin for EV and Energy Systems
Electric vehicle (EV) and renewable energy systems present more demanding insulation resin requirements than conventional electrical applications. High voltage, wide temperature ranges, vibration, moisture exposure, and long service life expectations — all of these factors make correct resin system selection critical. Why Is Insulation Resin Critical in EV Systems? Compared to conventional vehicle electronics, EV […]
What Is Protolin? How Is It Used?
Protolin is a polyurethane-based two-component electrical insulation resin used for cable joint filling and junction box insulation. Manufactured in Turkey by KETENCİ San. Tic. Ltd. Şti., Protolin systems provide reliable long-term protection against moisture, water, vibration, and mechanical stress. What Does Protolin Do? Electrical cable joints and junction boxes are exposed to moisture, water ingress, […]
What Is Encapsulation? Difference from Potting
Potting and encapsulation are two of the most frequently confused terms in electrical and electronic component protection. While both methods serve similar protective purposes, they differ significantly in application method, depth of protection, and service accessibility. What Is Potting? Potting is the process of completely embedding an electrical or electronic component inside a resin-filled housing […]
Polyurethane vs Epoxy: Which Resin System to Use?
One of the most frequently asked questions in electrical and electronic component protection is whether to use polyurethane or epoxy resin. Both systems can deliver reliable insulation — but they differ significantly in mechanical behaviour, flexibility, temperature tolerance, and service accessibility. Polyurethane Resin: Key Properties Advantages: Wide hardness range — formulatable from Shore A (soft) […]

5 Criteria for Selecting a Potting Resin
Selecting a potting resin is not just a question of brand or hardness. The wrong system can lead to incomplete cure, mechanical cracking, service difficulties, or application failure. This guide covers the five most important criteria to evaluate when choosing a potting resin. Criterion 1: Service Access — Will the Connection Need to Be Reopened? […]
