Cheat Sheet
- Catalyst Function -
Catalysts are found in liquid monomer to speed up the polymerization reaction, reducing curing time and improving bond strength (Journal of Cosmetic Science). They activate the free-radical process so monomer molecules link rapidly into a durable polymer network. Remember the mnemonic "CATalyze" to recall how catalysts accelerate transformation.
- Main Ingredient: Ethyl Methacrylate -
To answer what is the main ingredient of most monomer liquids, it's typically ethyl methacrylate (EMA), prized for its lower odor and reduced risk compared to MMA (Professional Beauty Association). EMA's molecular formula (C6H10O2) balances flowability with strength. Think "E for Ethyl = Easy-flow" to memorize its role in smooth bead formation.
- Preferred Brush Type -
When quizzed on what brush is most often used for monomer liquids, the Kolinsky sable #6 or #8 brush is top choice, renowned for its fine tip and excellent liquid retention (Milady Standard Cosmetology). This brush controls bead size and detail work, crucial for crisp edges and even coverage. Tip: visualize "6 or 8 seals the fate" of a perfect acrylic bead.
- Apex Definition -
In nail enhancement, the highest point in the nail is known as what? It's called the apex or arch, serving as the stress-bearing peak to prevent cracking (Cosmetology Research Institute). Proper apex placement creates a natural curve and structural integrity. Use the "Apex = Peak" shorthand to nail down this concept.
- Mixing Ratio & Polymer Chemistry -
Most acrylic systems require a 2:1 or 3:1 powder-to-liquid ratio to achieve optimal consistency and working time (University Cosmetology Department). Too much liquid weakens the polymer chain, while too little hinders adhesion. Remember the formula "3P:1L = Strong Shell" to ensure reliable set and durability.
