What Is The Mixing Ratio For Epoxy Resin?
To achieve the right 2:1 mix ratio by volume, measure 2-parts resin to 1-part hardener before combining the components. This will produce a 2:1 ratio by volume when mixed with the hardener.
To determine the correct mix ratio for your application, you will need to weigh the components first and mix them as per above to determine your final mix ratio by weight (i.e., equal parts resin to equal parts hardener).
However, if you are using a wide range of additives in your project, such as fillers, catalysts, accelerators, exterior coatings, or hardeners, the actual level of these materials will vary. These components will also vary with temperature.
This means that the 2:1 ratio by volume may not always be correct for your application. To ensure consistency and results, always follow the manufacturer’s recommended mix ratio by weight and make adjustments with larger amounts of add-on components if needed to achieve the correct mix ratio.
In addition to resin and hardeners, liquids are often added to epoxy resins. Some of these may be anti-microbial additives, dyes, fillers, pigments, or other additions to your resin.
These additives will lower your overall mix ratio depending on the amount added. Always refer to your resin’s instructions and data sheets for guidance regarding the appropriate mix ratio.
Can Epoxy Resin Be Used On Wood?
You can apply epoxy resin to almost any hard or soft surface. Epoxy resin for wood is a two-part adhesive that provides superior strength and water resistance.
It is designed to bond wood to wood, wood to metal, and metal to wood. Epoxy adhesives are not designed for bonding stone, glass, ceramic, or other non-porous surfaces to wood.
Because the epoxy resin is water-resistant and heat-resistant, it makes an ideal material for various projects with large exposure to weather elements or extended periods of use in high-stress environments. Because epoxy resins are solvent-free, they do not emit toxic fumes when applied; therefore, it is considered a much safer alternative than traditional glues and adhesive products.
A strong and long-lasting connection, DIYers and experts, love epoxy glue for wood for its remarkable strength and long-lasting adherence. It produces long-lasting, watertight seals that are simple to clean, sand, and drill. Because of these characteristics, it is perfect for use on wooden furniture.
However, some types of wood have been shown to resist epoxy resins naturally. This is especially true of wood that has not been exposed to fresh air for a long time.
Softwoods such as pine, fir, spruce, and balsa are more susceptible, while hardwoods such as walnut, ebony, and teak are less so. In addition, hardwoods are the most sensitive when cured in UV light which causes the resin to become less effective on these materials over time.
