Cementitious tile adhesives require a careful balance of open time, slip resistance, workability, and water retention — all of which must be maintained under varying environmental conditions and with different raw materials. GinShiCel cellulose ethers are engineered to bring reliable and consistent performance across a wide range of adhesive formulations, from standard to highly deformable systems.
GinShiCel enhances open time and adjustability, allowing installers to reposition tiles even under warm or dry conditions. It improves anti-slip performance, minimizing tile sag on vertical surfaces and making it suitable for heavy or large-format tiles. The modified rheology delivers a creamy, smooth workability, which helps reduce installer fatigue and ensures uniform coverage.
Its excellent water retention capabilities are especially valuable when applying adhesives to absorbent substrates or working in hot climates. By helping maintain moisture during the critical curing phase, GinShiCel supports proper cement hydration, resulting in higher bond strength and durability.
GinShiCel also offers various performance modifications such as varying water demand and extended open time, which help with worker efficiency and batch stability in dry-mix formulations. This allows manufacturers to maintain tight control over product consistency while tailoring behavior to regional installation methods, climate conditions, and substrate variability.
GinShiCel helps adhesive producers meet international standards such as EN 12004 and ISO 13007, while also delivering the formulation adaptability needed for diverse global markets.
In general, with higher viscosity grades, the dosage must necessarily be reduced to avoid much-increased water demand and cement shrinkage-related weakness. Conversely, low dosage means inadequate water retention for lower viscosity grades, leading to shorter open time and lower strength.
GinShiCel MH 133-M at 0.25% to 0.35%
GinShiCel MH 336-X3 at 0.2% to 0.25%
GinShiCel MH 512-AX at 0.15 to 0.2%
For tile grout, usually the particle sizes of the aggregates are very fine, leading to a generally high water demand, thus we cannot use high viscosity products. Also, because grout has a much lower exposed surface area comparing with tile adhesives - during application. This means that high water retention is also not needed.
GinShiCel MH 37-S fits this application quite well. Recommended dosage is at around 0.2%
