We often see different ratios for epoxy resin and curing agents, such as 1:1, 2:1, 3:1, or even 5:1, depending on the application. But how are these ratios determined, and what is the science behind them? To illustrate, let’s take the example of 128 epoxy resin (with an epoxy equivalent weight of 184-190 g/eq) and D230 curing agent (with an amine hydrogen equivalent weight of 61 g/eq). Achieving an ideal balance requires calculating the mix ratio based on these equivalent weights. Assuming an epoxy equivalent weight of 184 g/eq, the mix ratio can be calculated as follows: Curing Agent Amount = (184 g/eq Epoxy) / (61 g/eq Curing Agent) ≈ 3:1 This ratio of approximately 3:1 ensures that each epoxy group in the 128 resin has a corresponding curing agent group to react with, forming a durable and tightly crosslinked structure. If flexibility or impact resistance is needed, the ratio can be adjusted to slightly reduce the curing agent, enhancing the material’s toughness and elongation. Understanding the underlying logic of epoxy-to-curing-agent ratios allows us to tailor formulations to specific performance requirements, achieving ideal material properties. #EpoxyResin #CuringAgents #MaterialScience #128epoxyresin #D230hardener #ChemicalBalance

Poly Bridge Restoration Pain Points & OMEGAS Solutions Curing Time and Workability Pain Point: Polyester mixes can have a short working time, making it challenging to transport pre-mixed materials to the site without risking premature curing. Solution: Using an OMEGA volumetric mixer allows the polyester mix to be prepared on-site, ensuring it's fresh and workable when applied. This reduces the risk of the material curing before it can be properly placed, ensuring a smoother application process and higher-quality results. 2. Precise Proportioning of Resin and Aggregate Pain Point: Achieving the correct ratio of resin to aggregate in polyester mixes is critical for structural integrity, but pre-mixed batches may not always meet the required specifications. Solution: OMEGA Volumetric mixers allow for precise control over the proportions of resin and aggregate in the polyester mix. This ensures that the mixture meets the specific strength and performance requirements needed for effective bridge restoration. 3. On-Demand Production for Complex Projects Pain Point: Polyester mixes often need to be tailored to specific sections of a bridge, depending on the wear and damage. Using pre-mixed materials limits flexibility and can lead to overproduction or underproduction of the required material. Solution: With an OMEGA volumetric mixer, you can produce the exact amount of polyester mix needed, adjusting the formulation as required for different parts of the bridge. This on-demand production prevents material shortages or excess, improving project efficiency and reducing costs. OMEGACONCRETEMIXERS.COM #POLYESTER #POLYMIXER #VOLUMETRIC #OMEGA #SOLUTIONS

Did you know that, when we’re talking about self-leveling compounds, we’re talking about highly complex formulations? They can consist of up to 15 ingredients! The bulk of the ingredients in an SLC is made up of aggregates, such as silica sands and fine fillers, followed by inorganic binders, such as cement. The polymer content ranges from 1% for thick-layer compounds to 8% for special applications, e.g. self-leveling compounds for wooden flooring or on steel. Also very important for the system are the superplasticizers and additives, such as accelerators, retarders, thickeners, defoamers and so on. So, given all these different components: how do you find the perfect formulation that meets your needs? Contact our colleagues at your nearest Technical Center. They will gladly help you in conducting tests to find the right solution. 👉 For an overview of our product recommendations for drymix 1K and dispersion-based 2K self-leveling compounds and their application, check out our product page: https://bit.ly/42HtHuw #selfleveling #flooring #construction #vinnapas
