Product Overview

EL125C is a cost effective general-purpose encapsulation system suitable for use in low to medium voltage applications. It is specifically designed for the cost effective application of transformers, capacitors and cable joints. EL125C offers low viscosity, long pot life, low shrinkage and excellent adhesion and water resistance.
The standard colour is black but other colours like natural beige and grey are available on request.

How To

A Guide to Processing and Curing

Usable life
This is the time normally in minutes that the mixed resin is ‘usable’.

Working life
This is the time normally in minutes that the mixed resin is ‘workable’. 

Pot life
This is the time to double the initial mixed system viscosity.
 
Viscosity
Viscosity is the resistance to flow. A high viscosity resin has high resistance to flow e.g., treacle. A low viscosity resin has low 
resistance to flow e.g. water. 

Curing
Curing is the process by which resins react to produce a solid infusible mass. The reaction of resin and hardener usually 
involves the liberation of heat called exotherm. This is generally controlled by careful formulation and the addition of fillers and 
additives that suppress excessive heat build up. It is however dependant on the ambient temperature and the mass of material used. Smaller masses and lower ambient temperature will extend cure time and larger masses and warmer ambient temperatures will reduce cure time. Hotter temperatures may be used for faster cure but will result in higher post cure shrinkage and higher cure exotherm.  Experimentation and testing is suggested to avoid side effects.  For maximum properties a post cure may be required - call Robnor Technical Service Department for advice. 

Please consult the technical data sheet before using Resin-Online products. 

Post Curing
In many resins the performance of the system can be enhanced by a process called post curing. This involves a secondary 
cure process over and above the normal conditions to provide enhanced performance. In general post curing will improve such properties as; chemical resistance, temperature stability, dimensional stability, voltage breakdown resistance, water resistance and increase glass transition temperature. Post curing is mainly used on epoxy systems but can also be used on some high performance polyurethanes to enhance them still further. In general post curing occurs at 10 – 20.C above the maximum expected service temperature. 

Typical post curing (depending on system), may involve a normal cure plus: 
        16 hrs at 100.C or 
        8 hrs at 120.C or 
        4 hrs at 140.C or 
        2 hrs at 150.C
