Our firm is ranked amongst the reputed names in the market for offering an extensive range of Epoxy Accelerator.
Besides, we present this series to our clients at nominal prices.Product Details:
HSC 5510 is liquid amine accelerator. The liquid hot curing system goes for castings with good electrical and mechanical properties.
Application and Key Properties:
Indoor electrical insulators for medium/ high voltage like post insulators and bushings, Instrument transformers, Dry type distribution transformers, Switch gears.The system offers superior mechanical, electrical and thermal endurance properties
along with good resistance to atmospheric conditions.
Processing and Storage:
Casting resin system generally needs long working time. All components need to be mixed properly at room temperature or slightly higher temperature, vacuum may be used to assist mixing. Ensure proper filler wetting takes place which will result in
right processing viscosity needed for application. The proper mixing will ensure better flow properties thus reducing tendency to shrink which enhances mechanical, thermal properties and improvement in partial discharge behaviour for high voltage applications.
For plants that require a resin and hardener feed can mix resin, flexibilizer and filler on one side (Part A) while hardener and accelerator on other side (Part B) and can store at slightly elevated temperatures of 50°C and above for 3-5 days. Prolonged storage of resin along with fillers causes precipitation. Hence it is advisable to mix fillers before preparation. Materials to be thoroughly mixed prior usage including bottom of the container. Uneven mixing will affect the final cured properties.
Filler need to dried for removal of moisture prior to use. We recommend silanized silica which assist in proper bonding of organic material (epoxy) with inorganic part(silica).
Air release agents/ Defoamer can be used if mixing generates exorbitant air bubbles.
Mixing time depend on temperature, mixing equipment and quantity taken. Vacuum required for application should be between 0.5bar to 5bar.Curing
Once all the components are mixed, they need to transferred in pre-heated moulds, they are cured at specified temperature and post cured for achievement of properties and subsequently cooled for specified number of hours before demoulding.
We recommend use of a good mould release agent which should be sprayed or brushed properly on mould before transferring of epoxy material which assist in proper demoulding.Mould temperature:
Conventional vacuum casting 80 - 100°C
Demoulding times (depending on mould temperature and casting volume)
Conventional vacuum casting 6 - 12h
Cure conditions (minimal post-cure):
Conventional Vacuum Casting
6h at 80°C + 10h at 130°C or 6h at 80°C + 6h at 140°C
Castings of larger volume need to be done carefully at around 80°C. This will help in control of exotherm. High peak exotherm need to be avoided as they tend to crack a part. Peak exotherm control agents can be used for applications where higher exotherms are expected.Storage Conditions:
Components should be stored away from light & heat. Partly emptied containers should be tightly closed immediately after use to avoid exposure to light.
