Hydroxypropyl Methylcellulose (HPMC) 100g

Hydroxypropyl Methylcellulose (HPMC) Powder, Smooth Thickener for Gypsum, Tile Adhesive & Crafts

Need a smoother, longer-working mix? Hydroxypropyl Methylcellulose (HPMC) is a fine white powder used to improve thickness, smoothness, and water holding in gypsum, cement, plaster, and craft mixes. It helps your mixture stay soft and workable longer, so it is easier to spread, shape, and cast.

HPMC is popular in tile adhesive, wall putty, plaster, cement crafts, and projects because it helps reduce fast drying and cracking.

Why HPMC Helps:

Makes mixes smoother and creamier
Helps hold water longer
Slows down fast drying
Gives more working time before hardening
Helps reduce cracks and rough texture
Improves spreading and shaping
Helps powder and water mix more evenly

HPMC vs Other Common Thickeners:

• HPMC vs HEC: HPMC gives thicker, creamier texture and better water holding. HEC feels lighter and smoother.
• HPMC vs CMC: HPMC is less sticky and gives better smoothness. CMC is stronger for binding and glue-like thickness.
• HPMC vs Xanthan Gum: HPMC gives a cleaner and creamier mix. Xanthan can feel heavier and more gummy.

HPMC is best when you want smooth thickener, better work time, and slower drying that helps gypsum, cement, plaster, and craft mixes stay workable longer. It gives better smoothness and water retention than HEC, CMC, or Xanthan Gum.

Best Uses for HPMC Powder:

• Tile adhesive for better grip and smoother spreading
• Wall putty and plaster for easier application
• Gypsum and POP casting projects
• Cement crafts and decorative molds
• Repair mortar and patching mixes
• Art and craft projects
• Paints and coatings to improve smooth flow
• Cosmetic gels and creams
• Tablet and capsule production

How to Use HPMC Powder:

1. Measure the needed amount of HPMC powder
2. Mix it well with dry powder ingredients first
3. Add water slowly while stirring continuously
4. Keep mixing until smooth
5. Wait 5-15 (minimum) minutes for Initial thickening effect (Full activation may take 20-45 minutes)

Recommended Amount: Usually 0.2% to 0.5% of total dry mix weight. (Example: For 1kg dry mix, use about 2g to 5g HPMC.)

Helpful Tips:

1. Mix dry powder properly before adding water
2. HPMC thickens slowly, so wait a few minutes before adding more
3. Too much HPMC can make the mix too sticky
4. Store in a sealed container to keep moisture away
