DESCRIPTION

Tylose MH 200 YP2 is typically supplied as a white to off-white free-flowing powder designed for addition to dry mixes.
Tylose MH 200 YP2 is a cellulose ether that hydrates in water to form a viscous solution with shear-thinning behavior that supports easy application under shear and stable build at rest.
Tylose MH 200 YP2 improves water retention by slowing water migration into porous substrates and reducing evaporation during curing and setting.

Tylose MH 200 YP2 improves cohesion of mortars and reduces segregation by increasing the viscosity of the aqueous phase during mixing and application.
Tylose MH 200 YP2 can improve anti-sag and open time by supporting a stable paste structure and reducing rapid water loss at the surface.
Tylose MH 200 YP2 performance depends on dosage, mixing procedure, cement chemistry, filler selection, and jobsite temperature and humidity.

Tylose MH 200 YP2 should be dispersed properly to avoid lump formation and to ensure full hydration and consistent viscosity development.
Tylose MH 200 YP2 should be protected from moisture pickup because humidity can cause caking and reduce dispersibility.
Tylose MH 200 YP2 is commonly selected when consistent workability, water retention, and application stability are required in cement and gypsum systems.

FIRST AID

Inhalation:
Move to fresh air if dust is inhaled.
Seek medical attention if coughing or respiratory irritation persists.
Avoid breathing dust during handling and charging.

Skin Contact:
Wash with soap and water after contact.
Remove contaminated clothing and wash before reuse.
Seek medical advice if irritation develops or persists.

Eye Contact:
Rinse cautiously with water for several minutes.
Remove contact lenses if present and easy to do, then continue rinsing.
Seek medical attention if irritation persists.

Ingestion:
Rinse mouth with water.
Do not induce vomiting unless directed by medical personnel.
Seek medical attention if a large amount is swallowed or discomfort occurs.

Note to Physicians:
Treat symptomatically.
No specific antidote is required.
Provide supportive care based on exposure route and symptoms.

HANDLING AND STORAGE

Handling:
Use appropriate PPE including gloves and safety glasses.
Avoid generating dust during weighing, pouring, or conveying.
Wash hands after handling and before eating, drinking, or smoking.

Ventilation:
Use local exhaust or general ventilation where dust may be generated.
Maintain good airflow during charging and mixing operations.
Minimize airborne particulate accumulation in enclosed areas.

Storage:
Store in a cool, dry place away from moisture and humidity.
Keep containers tightly sealed and properly labeled.
Protect from contamination to maintain consistent dispersibility and viscosity performance.

Spill and Leak Procedures:
Sweep or vacuum spilled material using methods that minimize dust generation.
Collect in suitable containers for disposal according to local regulations.
Clean residue with water while preventing slip hazards because wet cellulose ether can be slippery.

Handling Precautions:
Avoid moisture pickup because it can cause lumping and reduced dispersibility.
Use clean, dedicated equipment for dry-mix production to prevent contamination.
Rotate stock using FIFO practices to maintain consistent quality and performance.
