DESCRIPTION

Tylose MH 200 YP2 is a cellulose ether polymer based on methyl hydroxyethyl cellulose, and Tylose MH 200 YP2 is supplied as a free-flowing powder designed to disperse and hydrate in water.
Tylose MH 200 YP2 builds viscosity by polymer hydration and network formation, and Tylose MH 200 YP2 helps stabilize cementitious and gypsum systems by controlling water mobility and particle suspension.
Tylose MH 200 YP2 improves water retention by slowing water migration into absorbent substrates, allowing better cement hydration and improved bond development.

Tylose MH 200 YP2 can improve open time and slip resistance in tile adhesives, supporting easier tile placement and reduced tile slippage on vertical surfaces.

Tylose MH 200 YP2 can be used together with starch ethers, redispersible polymer powders, and other additives to tune workability, stability, and strength development.

Tylose MH 200 YP2 should be stored in a cool, dry place in sealed packaging to prevent moisture pickup and caking.
Tylose MH 200 YP2 should be protected from contamination because small changes in polymer content can significantly affect mortar rheology.
Tylose MH 200 YP2 should be handled to minimize dust and to maintain consistent dosing accuracy in dry-mix systems.

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:

Remove contact lenses if present and easy to do, then continue rinsing.
Seek medical attention if irritation persists.

Ingestion:
Rinse mouth with water.
Seek medical attention if discomfort occurs or if a large amount is swallowed.
Never give anything by mouth to an unconscious person.

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, and use dust protection as needed.
Avoid generating dust and avoid inhalation of fine powder.
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 weighing, charging, and mixing operations.
Minimize airborne particulate accumulation in enclosed areas.

Storage:
Store in tightly closed original packaging in a cool, dry place.
Protect from moisture to prevent caking and to maintain consistent hydration performance.
Keep away from strong odors, contaminants, and direct water contact.

Spill and Leak Procedures:
Avoid dust generation and sweep or vacuum using equipment designed for fine powders.
Place collected material into suitable containers for disposal according to local regulations.
Clean the area with wet wiping if needed to reduce dust dispersion and slip risk.

Handling Precautions:
Pre-blend Tylose MH 200 YP2 with dry fillers when needed to improve dispersion during mixing.
Control dosing accuracy because small dosage changes can significantly affect open time and sag resistance.
Rotate stock using FIFO practices to maintain consistent quality and predictable mortar performance.
