How to Protect Electrical Connections Against Moisture Moisture is one of the most common causes of electrical connection failure. Water ingress, humidity and condensation can damage terminals, cable joints and electrical enclosures over time. Proper electrical insulation and sealing systems are essential for protecting electrical infrastructure in outdoor, underground and industrial environments. Why Moisture Protection […]

Re-enterable Electrical Insulation Resin for Junction Boxes and Cable Connections
Re-enterable Electrical Insulation Resin for Junction Boxes and Cable Connections Modern electrical infrastructure increasingly requires insulation systems that are not only protective, but also removable and serviceable when maintenance is needed. Re-enterable electrical insulation systems are designed to protect electrical connections against moisture, water, dust and environmental conditions while still allowing future access to cables […]
5 Common Mistakes in Polyurethane Resin Application and How to Avoid Them
TR | EN Technical Guide · Application 5 Common Mistakes in PolyurethaneResin Application and How to Avoid Them Polyurethane resin systems deliver highly reliable insulation when applied correctly. However, common application mistakes can lead to incomplete cure, sticky surfaces, air voids, or premature mechanical failure — all of which compromise long-term performance. protolin.net · Technical […]
IP68 Junction Box Potting: Rigid, Elastic and Gel System Selection
IP68 protection for electrical junction boxes can be achieved with the right resin system and thorough application. However, not all junction boxes have the same requirements: some locations need permanent maximum protection, while others require regular service access or the ability to take probe measurements without removing the insulation. This guide covers three resin system […]
Transformer Coil and Inductor Potting
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
IP67 and IP68 are among the most frequently cited specifications in electrical and electronic component datasheets — but what do these codes actually mean, and how do they relate to electrical insulation and potting applications? How to Read an IP Rating The IP (Ingress Protection) rating is defined by IEC 60529 and consists of two […]
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, […]
