Engineered to meet the stringent demands of machine-applied cement plasters across France, from Paris to Marseille.
France's building sector is undergoing a profound transformation driven by the strict RE2020 (Réglementation Environnementale 2020) standard, which mandates low-carbon construction materials and high thermal efficiency. In modern French building sites—stretching from the urban expansions of Lyon to the heritage restoration zones in Bordeaux—efficiency and sustainability are paramount. Cement spray plastering has become the dominant method for finishing both interior and exterior walls, significantly reducing labor time and material waste.
However, machine projection of cement-based mortars presents unique physical challenges. The high pressure from spraying machines, combined with varying substrate absorption rates (such as high-suction aerated concrete or clay bricks common in France), requires specialized additives. Methyl Hydroxyethyl Cellulose (MHEC) acts as the vital backbone of these formulations. It controls water retention, prevents premature desiccation, and ensures smooth pumpability through long hoses without clogging.
MHEC optimizes water usage in dry-mix formulations, enabling the use of eco-friendly binders and recycled aggregates without compromising mortar strength or workability.
Reduces friction in spraying equipment (such as Lancy or Putzmeister machines), preventing segregation and ensuring a continuous, uniform spray pattern.
Crucial for Southern France's hot summers (e.g., Marseille and Nice), preventing rapid water loss to the dry atmosphere or porous substrates.
Since its establishment in 2002, our company has embarked on a 23-year journey of relentless growth and innovation within the global arena of specialty chemical additives.
As a specialised manufacturer and supplier, we focus on producing advanced specialty chemical additives that are critical components in diverse industries, including cellulose ethers (HPMC, MHEC, HEC), redispersible polymer powder (RDP), HPS, PCE, CMC, PP fibre, etc.
Looking to the future, we are committed to leveraging our 23 years of technical and market insight to redefine industry benchmarks and ensure that our products meet our customers' expectations better.
From modern eco-districts to historic preservation, Jinji Chemical MHEC adapts to diverse French construction environments.
Parisian limestone facades require highly breathable lime-cement plasters. Our MHEC ensures slow, even curing, preventing cracks on historic substrates while maintaining structural breathability. This makes it a preferred choice for contractors working under the supervision of the Architectes des Bâtiments de France.
With rapid urbanization in Lyon's commercial districts, speed is key. Mortar projection machines require plasters with high sag resistance and long open time. MHEC ensures the wet plaster sticks to vertical walls immediately upon projection without sliding, allowing workers to level large surfaces quickly.
Southern France experiences extreme summer heat. Standard cement plasters dry too quickly, leading to shrinkage cracks and loss of final strength. The high thermal stability of Jinji Chemical's MHEC guarantees water retention even in ambient temperatures exceeding 35°C, ensuring complete cement hydration.
Lille's sustainable housing initiatives focus on low-carbon footprints. Our MHEC allows formulators to reduce cement content by replacing it with local bio-sourced aggregates (like hemp or wood fiber) while maintaining the cohesion and sprayability of the plaster matrix.
In cement-based spray plastering, MHEC operates at a molecular level to control the kinetics of water migration. When dry-mix plaster is mixed with water in the spraying machine's mixing chamber, MHEC dissolves rapidly, forming a three-dimensional polymer network. This network increases the viscosity of the aqueous phase, trapping water molecules and preventing them from being sucked out by dry substrates or evaporating into the air.
Key benefits for French plastering applications include:
Tailored grades for construction chemical blending, dry-mix mortar manufacturing, and ready-mix plastering systems.
