It is classified into ordinary and specialty types.Its composition includes cement and gypsum as binders; quartz and manufactured sand as aggregates; mineral admixtures like fly ash and slag; and functional additives. MIXEON HPMC provides water retention, thickening, and improved workability, preventing cracking and sagging. MIXEON RDP enhances bond strength, flexibility, crack resistance, impermeability, and abrasion resistance, extending mortar durability. Together, they optimize workability and finished quality.
Comparison of Cement-Based and Gypsum-Based Mortars
| Mortar Type | Key HPMC Requirements | Key RDP Requirements |
| Cement-Based Mortar (e.g., exterior renders, repair mortars) |
High water retention: Slows water evaporation during cement hydration, ensuring proper curing and preventing cracking or strength loss. | High bond strength: Significantly improves adhesion to various substrates such as concrete, tiles, and insulation boards. |
| Thickening and anti-sagging: Provides good thixotropy to prevent sagging in thick-layer applications, especially on vertical surfaces. | Flexibility: Absorbs stress from temperature changes and substrate shrinkage, reducing the risk of debonding and cracking. | |
| Open time control: Maintains sufficient working time under high temperatures or windy conditions. | Water resistance: Enhances bond strength even after water immersion, suitable for exterior and wet-area applications. | |
| Compatibility: Works well with cement, sand, and various additives without causing retardation or strength loss. | Durability: Improves freeze-thaw resistance, impermeability, and abrasion resistance, extending service life. | |
| Gypsum-Based Mortar (e.g., gypsum plasters, joint compounds, gypsum adhesives) |
Moderate water retention: Matches the fast-setting nature of gypsum to prevent rapid surface drying that can lead to powdering or reduced strength. | Improved adhesion and cohesion: Enhances bonding between gypsum and substrates, reducing the risk of delamination or hollow areas. |
| Smooth workability: Provides a fine, easy-to-spread texture that reduces application effort. | Lower flexibility requirement: Gypsum-based systems generally do not endure significant movement; RDP primarily improves flexural strength and surface hardness. | |
| Stable pH environment: Maintains viscosity stability in the neutral or slightly acidic conditions typical of gypsum-based systems. | Reduced surface powdering: Forms a continuous polymer film that seals surface pores and enhances wear resistance. | |
| Low air entrainment: Avoids excessive air bubbles that could compromise surface finish and strength. | Improved moisture resistance: When used in humid environments (e.g., bathrooms), RDP can help enhance water resistance, especially when combined with waterproofing additives. |
