Εpoxic Resin for castingby El Greco Liquid glass 1/1 ratio

Product description
The epoxic resin for casting by El Greco Liquid glass 1/1 ratio is a clear epoxic resin appropriate for casting/ filling, or in silicone molds, or in metallic/ polyester casts, or directly upon in surfaces that require filling ( cavities in wooden surfaces) and it gives a beautiful, hard and shiny final reuslt.
it can be used for castings of any thickness in combination with other materials such as: coins, wood, and small stones, e.t.tc. Re- leveling resin that when dry it creates a extraodinary, soft and shiny surface, that does not need leveling, or any surfacing. But, if you wish to make the resin even shinier, for an extra polishing it can be doen with a sandpaper or surfacing ointments. Special additives inside the resin contribute in the ejection of the trapped air after the mix. As a result, in most cases there is no need of the disappearance of bubbles with a torch. The previous composition (UV) gives the resin a protection in yellowing in comparison with conventional epoxic resins, however the product is intended for structures within the interior space.

Basic resin characteristics

  • Very thin fluid, re- leveling epoxic resin

• Making of jewelry
• Combination with lots of materials such as: concrete, metal, glass, plexiglass, ceramic for constructions.

How to use it
The epoxic resin for casting - EL Greco Liquid glass 1/1 ratio has been created so that it has an easy usage and even people with small or no experience at all can succed in remarkable results. It is important for the users to be familiar with the information below & follow right the instructions, especially when it comes to working temperature, weighning & mixing. Non satisfactionable results are almost always credited to non - appropriate enviroment temperature or improper weighing or mixing

Before you start...

Enviroment temperature
This system has been designed to function in a environment with temperatures between 15 - 30°C. For maxiumum results, it is suggested (20-25°C. Do not use the liquid glass in temperatures below 15°C, because the druying will be delayed a lot so it may not be completed fully with a reuslt of the resin staying sticky.

Humidity
During druying the liquid glass can absorve humidity through air. In enviroments with high humidity this absorving can affect the finish of the surface. Therefore, you should avoid to apply it in a environment with a humidity of 70% or more. This phenomenon is deepening a lot in enviormnets with low temperatures in which the druying is delayed & leaves behind a non - hardened resin exposed to humidity for a long time.
Preparation of a surface
Τo The liquid glass can be affected unfavourably from any moisture that is on the surface that is applied. The surface that the liquid glass is applied must be as dry as possible and and stable. Especially working with natural materials such as: wood, corks or concrete that have plenty of moisture. Wood that have been recently sawed or come from a moist enviroment (sea- wood) are important to dry well (this can take from days or weeks in an internal space) before it's use. If the material is not properly dry & stable it can prevent the full druying of the resin or it can blur the resin because of the moisture.

Weatherproofing - Is necessary for all porous surfaces When working with porous underlays (wood, concrete or ceramic) it is suggested to seal it first with a layer of solventborne epoxic primer El Greco so the incoming moisture is prevented. After 5 hours of it's application you can move on with casting.

Absorption - Entrapment of objects. Any materials that will be integrated inside the resin , such as: wood, leaves e.t.c must be completely dry. Porous objects (absorb resin). They first must be sealed with a primer & then dry out fully before the casting.

 

Mixing ratio 1/1 by volume

The/span>EL Greco Liquid Glass 1/1 ratio must be mixed with the epoxic hardener (B' component in a 1/1 ratio by volume). When working with epoxic resins, it is necessary to follow the mixing ratio. A wrong mixing can have as a result only a slight hardening of the system. Never add more hardener so you can accelerate the time of maturation.

Mixing instructions
Weigh properly the ratio of the resin + hardener (A' + B' components) with a flat bottom & mix with a mixing tool. Stir the mixture for 3 minutes until it becomes completely transparent & homogenous but be careful as to not leave any of it on it's walls & the bottom of the container that was not stireed. After you finish the stirring process in the container, it is
a good practic to move the the mixture to a second clean container for stirring. Repeat the stirring for another 3 minutes using a new mixing tool. By doing this, you eliminate the danger of using an improperly mixed mixture.

Time of working with the mixture
From the moment of stirring of the resin and the hardener, you have 2-5 hours available to apply the product. After the passing of the 4 hours, it begins & builds up the viscosity of the resin meaning it becomes thicker and much difficult to use.

 

Time Of Hardening
The EL Greco Liquid glass 1/1 ratio requires 48 hours in order to harden and be detached from the mold, to reach its' full hardness it takes a couple of days. After waiting for 14 days in temperature 230°C the hardness of the resin will be complete.

Temperature of the environment: The epoxic resins are thermo-hardening plastic matter, which means that their hardness is linked to the temperature: The hardness will accelerate with the high temperature of the environment and will be delayed in low temperatures. Also, the viscosity (the thickness of the resin) increases (becomes more thick) as long as the temperature of the enviroment drops and in reverse in high temperature it becomes thinner as a fluid.
Mass Affection: The bigger the quantity of the resin that has been casted, the hardening becomes faster. In bigger castings (large quantities of resin) you will observe that the mixture becomes hot.
Tests: It is highly reccomended to run small tests before the final application of the resin so you can find out how is both the hardener and the resin affected in relation to different parametres for example. temperature, thickness of casting e.t.c but also how the materials that are entrapped in the resin may likely affect teh hardening process.

Trapped Air - Is a thermal pistol needed or a blow torch?The previous technology ofEL Greco Liquid glass 1/1 ratio ejects entrapped air that was in the time of mixing. The resin usually vaporizes by itself in a big degree leaving behind a beautiful surfacing with no bubbles. After the mixing of the base with the hardener let the mixture to be still and gasify for 10-15 minutes or much longer (big time of working: 5 hours) and move on later to casting. If you still see bubbles, use a thermal pistol on soflty on it or a torch.

Security Measures
Work in a well aired space. Always wear protective gloves on and goggles everytime you weigh/stirr/cast the resin. Do not touch the surface without gloves until it becomes harder.

 

Creating a mold - wall
The resin is meant for castings and it is a thin fluid so if we cast in a area that is nto properly sealed on the sides (dry/secure mold) the resin will drop out of the mold. If we want to for instance apply it as a thick layer on a surface (wooden table, counter e.t.c) we have to create a wall around it completely dry for the holding of the resin using a thick shiny cardboard & plastic sticky tape. You must be certain that is leak-proof before casting.

Colouring the resin
You can add special pigments in the resin so the final result can be coloured. By adding small doses of pigments you will have achieved a transparent mixture (you will be able to see through it)but it will have the desired colouration (blue, green, purple, red, yellow e.t.c. You should add pigments that are compatible with the resin and not some that may be non-compatible. Also, you can combine special powders that glow in the dark or even glitter powders.

 

 

Handling Of Problems

1) Blur or solidified resin in the bottle: The resin has crystallized because of the low temperature. After it has been re-heated inside the container in about 50° C that resin will become a fluid again.

2) It has not been hardened after 48 hours: Wrong mixture ratio or low temperature.

3) The mixture gets too hot: High temperature in the working area or a great amount of mixture has been made.

4) There are bubbles trapped inside the mixture: The mixture happened too fast and there was not enough time for the resin to eject the air in it.

5) The final result is sticky or oily: The level of the humidity (of the enviroment) of the room is too high.

6) The resin will not stick to the walls of the surface it was casted: The surface was not properly cleaned or there was moisture on the surface.
