Ultra Clear Epoxy 101: Table Top Epoxy vs. Casting Epoxy

Leave a Comment

As a way of adding protection and gloss to items, ultra clear epoxies are widely used for bars, tabletops, river tables, jewelry, and much more. Epoxy resins are a popular product used for various applications. However, determining the best type of epoxy for your project can be difficult. 

Two common types of epoxies are table top epoxies and casting epoxies. While the two are very similar, they each have their unique properties and ideal uses. Regardless of the epoxy needed for your project, be sure to read and follow the manufacturer’s instructions because mistakes can have a huge impact on the final product. 

Table Top Epoxy vs. Casting Epoxy

Two of the most popular ultra clear epoxies are table top epoxy and casting epoxy. These two share similarities, but they are very different to work with and are meant for different applications.

Table Top Epoxy

Table Top EpoxyAs the name implies, table top epoxy is best for pouring over flat surfaces, such as table tops, bars, counters, or resin art. It is a self-leveling epoxy meant for thin pours in thicknesses of usually 1/4’’ or less. Pour thicknesses vary depending on the application, but it is important to note that using table top epoxy for embedding thick objects takes several applications and hours. 

With table top epoxy’s recommended 1:1 mixture, it is ideal for use by both beginners and professionals. The main advantages of table top epoxy over casting epoxy are its higher viscosity and faster cure time of 12-24 hours. 

Casting Epoxy

Casting EpoxyAlso referred to as deep pour resin, casting epoxy is used for thick pours of up to 2’’. Casting epoxy is commonly used for river tables, embedding and encasing objects, jewelry, and more. It offers a lower viscosity than table top epoxy and a slower cure rate of 24-36 hours. 

The longer cure time for casting epoxy allows for a longer working time, but care must be taken to prevent dust and debris from settling into the resin. The typical mixture for casting epoxies is 2:1, although some manufacturers have variations with a 1:1 or 3:1 ratio. 

Advantages of Ultra Clear Epoxies

There are several features of ultra clear epoxies that make them ideal for many applications. Advantages of using ultra clear epoxies in your project include:

  • Blush Resistant. Even in high humidity conditions, ultra clear epoxy does not blush or sweat. 
  • High Gloss. The formula for ultra clear epoxy cures with a highly glossy and transparent finish. To achieve this polished appearance, it typically takes only three coats or less. 
  • Simplified Mix Ratios. Simple mix ratios make using ultra clear epoxies easier to measure and mix. This makes it preferred by many as it reduces the risk of minor errors that affect the final product. 
  • Tough Surfaces. Ultra clear epoxies are formulated to tough industrial standards, providing indestructible surfaces for your project. Epoxy results in long-lasting, maintenance-free surface protection that resists scratching, yellowing, and distortion.
  • Wood Adhesion. Ultra clear epoxies are the ideal solution for porous materials, helping protect the surface while accentuating the wood’s natural features.

Applications of High-Temperature Epoxies

Leave a Comment

Epoxy resins adhere and cure on hard surfaces, providing a versatile polymer adhesive. Beyond their temperature-resistance capabilities, high-temperate epoxies feature many favorable qualities, including resistances to moisture, chemicals, impact, and corrosion. 

High-temperature epoxies maintain their properties even when exposed to extreme temperatures. Harsh industrial environments rely on high-temperature epoxy coatings over other adhesive types because of the improved heat resistance and durability they provide in severe operating conditions. This blog post will discuss the versatile nature of high-temperature epoxies and their uses across various industries. 

What is High-Temperature Epoxy?

For many applications, finding an appropriate high-temperature adhesive is vital for the success of the project. Manufacturers working in challenging environments often opt for a high-temperature epoxy resin, a specially formulated product that withstands temperatures up to 450°F and cures even in high-heat conditions. Other advantageous qualities of high-temperature epoxies include:

  • Durability
  • High abrasion resistance
  • Good clarity
  • Low viscosity
  • Thermal conductivity
  • Dimensional stability at high temperatures

These epoxy resins offer exceptional wetting characteristics when used in conjunction with aramid or carbon fiber. They display high degrees of chemical resistance and withstand steam exposure. Additionally, high-temperature epoxies are an ideal choice for encapsulation and potting, thanks to their thermal conductivity.

When the time comes to choose the appropriate adhesive for a project, it is essential to account for the expected operating temperature and the requirements for the product’s ultimate performance properties. Other vital considerations include:

  • Duration of exposure to high temperatures
  • The glass transition temperature of an adhesive
  • Coefficient of thermal expansion and bonded substrates
