This download provides specific information about our Clearpox brand epoxy resin, while all other advice and information on this page applies to the general use of epoxy resin:

Getting Familiar With Your Epoxy Resin

If you haven’t used epoxy resin before we recommend a trial mix on a small scale just so you can familiarise yourself with the resin, which will give a better idea and provide some essential experience which is ideal before undertaking large projects.

Mixing Ratio

It is vital that the resin is mixed at the right ratio. The ClearPox epoxy systems are mixed by volume 2:1. Mixing ratios are provided on product labels, they can also be accessed via the technical datasheet which can be viewed and downloaded from the website on the products page.

Temperatures & Humidity

Epoxy resins are temperature sensitive, it is important to pay attention to all aspects of temperatures, from the resin itself to the room in which the resin will spend its time curing. The ideal room temperature for the epoxy to cure is 25°C. The mould or object in which the resin will be poured in/on should ideally be around the same temperature.

Colder conditions will slow the cure of the resin and will not produce as high a quality finish as when used in the recommended conditions. Cold temperatures may cause the resin surface to blush, a lesser degree of self leveling on the surface and in extreme cases cause the resin to go cloudy with a sever reduction in clarity. Relative humidity also plays a part and ideally the humidity levels will be below 70% for best results. These specs are the ‘ideal’ however the epoxies will perform well from 18°C upwards, temperatures lower than 15°C will likely result in a poor finish.

Resin Quantities & Pot-life

The pot-life stated on the product TDS Technical Data Sheet is based on a 200g mix at 25°C. Colder conditions may prolong the pot-life as where hotter temperatures will decrease the pot-life. Increasing or decreasing the quantity of resin in the pot can also have a big impact on pot-life. Mixing large quantities of resin will greatly reduce the pot-life, this is especially true on short pot-life version (ClearPox). It is good practice to start out with smaller mixes until you gain experience and get used to the characteristics of the resin.

Cure Time

The cure time depends on the ambient temperature; if it’s hotter it will cure quicker. Generally, please allow 24 hours for your resin to cure at 25 degrees Celsius. Your project will be fully cured after 7 days

Quality of Mix

Improper mixing will lead to curing issues, so it’s vital the materials are well mixed. When the two components of the epoxy system are combined you will notice the material will turn hazy. Once mixing begins the clarity will return. It is important to mix until the material has cleared and there are no streaks. Take extra care to carefully scrape the sides and bottom of the mixing vessel. A good practice would also be to transfer the primary mix into a secondary mixing vessel and mix again to ensure the epoxy is thoroughly mixed.

Pigmentation

Pigments, Dyes, Pearlescent, Luminescence etc. will all typically work well with the ClearPox epoxy systems. These materials typically have a wide scope on quantities that can be added to the resin. Paste pigments and dyes will often have a recommended maximum addition due to the carrier used. Powder pigments and metallic powders would be a personal choice on quantities.

Metallic powders are not ideal for long pot-life resin (ClearPox) due to the powders densities which often cause them to drop out of suspension over time sinking to the bottom of the cast. Simulated metallic pigments and some pearlescent will tend to float as they are often lighter in mass than the resins. Trials on a small scale basis will again help you determine how much pigment suits your needs and provide the effect you require, and a good measure to test compatibility before using the material on a full scale.

Casting Depth

The recommended depth of cast on each system is primarily a recommended safe limit which is to ensure they will perform as expected providing they are used correctly. There are many variables involved in the depth of cast that might allow the resin to be used slightly over the recommended limits a few examples such as temperatures, filler added, shape of void (if filling), the substrate in which the epoxy is being cast in/on, all of which can have an effect. If unsure a trial test would help determine what will/won’t work. We recommend a pour depth of 20mm per pour with ClearPox. A deeper pour is possible once the first layer is set.

Sealing Coat

For porous surfaces such as wood, concrete or similar a sealing coat is recommended especially when deep casts are involved, a sealing coat stabilises the surface and also prevents air from escaping from the pores and getting trapped in suspension whilst the resin cures. The sealing coat would left to cure before sanding and cleaned to leave a keyed surface ready for the next layer or main layer.

When pearl pigments are used with epoxy resin, they exhibit several characteristic properties. Here are some common characteristics of pearl pigments when incorporated into epoxy resin:

1. Pearlescent or iridescent effect: Pearl pigments create a shimmering, pearlescent, or iridescent effect in epoxy resin. They contain coated mica particles that reflect and refract light, producing a multi-dimensional appearance with a play of colours and a luminous sheen.

2. Soft and subtle colour shifts: Pearl pigments offer subtle colour shifts and variations depending on the viewing angle and lighting conditions. As light interacts with the coated mica particles, it can create beautiful colour variations and a sense of depth within the resin.

3. Transparency and translucency: Pearl pigments are typically translucent in nature, allowing light to pass through the resin layers. This transparency helps to maintain the luminosity and depth of the pearl effect while allowing underlying layers or objects to show through.

4. Complementary to transparency: Pearl pigments work exceptionally well with transparent or translucent epoxy resin. When combined, they enhance the resin’s clarity and transparency, allowing the pearlescent effect to shine through and interact with the colours or objects beneath the resin surface. 

5. Versatile blending and layering: Pearl pigments can be easily blended and layered to create custom colours and effects. They can be mixed with other pigments or added in varying concentrations to achieve different levels of intensity or opalescence. Layering multiple coats of pearl pigmented resin can enhance the depth and brilliance of the pearlescent effect.

6. Compatibility with different mediums: Pearl pigments are compatible with various mediums, including epoxy resin. They can be used in combination with other pigments, dyes, or additives to achieve unique colour effects and enhance the visual appeal of resin art, jewellery, or other epoxy resin projects.

7. UV stability: Some pearl pigments are formulated to be UV resistant, ensuring their colour and shimmer remain stable even when exposed to sunlight or UV radiation. This makes them suitable for projects intended for outdoor or long-term display.

8. Non-reactive with epoxy resin: Pearl pigments are generally non-reactive with epoxy resin and do not interfere with the curing or chemical properties of the resin. They can be mixed and applied to epoxy resin without compromising its integrity or curing process.

It’s important to note that the specific characteristics and effects may vary depending on the brand, colour, concentration, and application techniques used with pearl pigments. Experimenting with different colours, layering techniques, and lighting conditions will help you explore and harness the unique qualities of pearl pigments in your epoxy resin projects.

Bubbles can appear in epoxy resin due to various reasons such as mixing, pouring and ambient conditions.  Here are some more common causes: 

1. Mixing: Improper mixing can introduce air bubbles into the epoxy resin. Agitating the resin and hardener vigorously or mixing too quickly can cause air to get trapped in the mixture. To minimize bubbles, mix the resin and hardener slowly and gently, scraping the sides and bottom of the mixing container thoroughly. Stirring in a circular motion can also help reduce the introduction of air. 

2. Pouring: Pouring the epoxy resin too quickly or from a height can create turbulence and result in bubbles. When pouring, try to pour the resin slowly and close to the surface to minimize agitation. Pouring along the side of the container or using a pouring tool with a narrow spout can also help reduce the chance of bubble formation. 

3. Ambient conditions: Temperature and humidity can affect the behaviour of epoxy resin and the formation of bubbles. Higher temperatures and humidity levels can accelerate the curing process, causing the resin to trap air more easily. Try to work in a temperature-controlled environment and avoid pouring resin in high humidity conditions, as they can contribute to the formation of bubbles. 

4. Exhaling or blowing on the surface: When trying to remove bubbles, blowing on the resin surface or exhaling directly onto it can introduce moisture and more air into the resin. This can create additional bubbles instead of eliminating them. Instead, consider using a heat gun, a torch, or a straw to gently remove bubbles by passing heat or creating airflow over the surface. 

5. Porous or uneven surfaces: If you’re working on a porous or uneven surface, air can become trapped within the substrate and migrate into the resin during the curing process, resulting in bubbles. To prevent this, make sure the surface is properly sealed, smooth, and free from any debris or contaminants. 

6. Additives: Certain additives like pigments, dyes, or glitters can contribute to bubble formation if they are not properly incorporated into the resin. To minimize bubbles caused by additives, mix them thoroughly with the resin before pouring and avoid using additives that are prone to air entrapment. 

7. Curing under pressure: If epoxy resin is cured under pressure, such as in a vacuum or pressure chamber, bubbles can form due to the release of dissolved gases. While these methods are often used for specific purposes, they can introduce bubbles if not done correctly. 

To reduce the occurrence of bubbles, take your time during the mixing and pouring process, work in suitable environmental conditions, use proper techniques for bubble removal, and ensure the surfaces and additives are prepared appropriately. Experimentation and practice will help you develop the skills to achieve bubble-free epoxy resin projects.
