Flow White Glue (Alternative to Latex Powder)

Redispersible polymer powder is a free-flowing white powder produced by spray drying of polymer emulsions (mainly vinyl acetate-ethylene copolymers, VAE). It rapidly redisperses in water to form a stable emulsion. After water evaporation, it forms a continuous, highly flexible and strongly adhesive polymer film, widely used in mortars to significantly improve adhesion, flexibility, crack resistance, and water resistance of inorganic materials.

Our Flow-Whitening Glue can partially or fully replace latex powder in mortar applications, with performance superior to conventional latex powder.

Ash content (1000℃): 12%–15%
pH value (5% aqueous solution): 5.0–8.0
Minimum film-forming temperature (MFT): 0℃–5℃ (excellent film formation at low temperature)
Glass transition temperature (Tg): -10℃–5℃ (adjustable by grade)

2. Dissolution & Film-Forming Properties

Redispersibility: Fast dispersion in room-temperature water; uniform emulsion formed within 3–5 minutes of stirring
Film formability: Transparent, flexible and highly elastic polymer film formed after water evaporation
Stability: Aqueous solution resistant to acid and alkali (pH 4–10), tolerant to common electrolytes, good compatibility with cement and gypsum
Thermal stability: Stable below 60℃; gradually softens above 80℃; slowly decomposes above 150℃

II. Core Performance & Mechanism

Enhanced adhesion: Forms a film at the substrate-mortar interface, greatly improving bonding to cement, tiles, insulation boards and walls
Improved flexibility: Reduces elastic modulus of mortar, bridges microcracks, and significantly enhances flexural, impact and deformation resistance
Better water resistance: Polymer film seals capillary pores, reduces water absorption, and provides hydrophobicity and impermeability
Optimized workability: Improves workability, fluidity and anti-sagging performance, prolongs open time
Increased durability: Enhances freeze-thaw resistance, aging resistance and carbonation resistance, extending service life

III. Main Applications (Construction Mortar Sector)

1. Tile Adhesive

Dosage: 2.5%–6.0% (Type C1: 2.5%–3.0%; Type C2/S1: 5.0%–6.0%)
Function: Improves bond strength, anti-slip performance, prevents hollowing and tile detachment, enhances water and aging resistance

2. Interior & Exterior Wall Putty

Interior wall putty: Dosage 1.5%–3.0%, prevents chalking, easy sanding, improves adhesion
Exterior / water-resistant putty: Dosage 3.5%–4.0%, crack-resistant, water-resistant, weather-resistant, prevents peeling

3. Thermal Insulation Systems (EPS/XPS Boards)

Bonding / rendering mortar: Dosage 4.0%–5.0%, enhances crack resistance, impact resistance and weatherability
Function: Forms a flexible protective layer to prevent cracking and delamination of insulation systems

4. Self-Leveling Mortar / Repair Mortar

Dosage: 3.0%–5.0%
Function: Improves fluidity, compressive and flexural strength, toughness, wear resistance and crack resistance

5. Caulking Agent / Waterproof Mortar

Dosage: 2.0%–4.0%
Function: Enhances compactness, flexibility, water resistance, impermeability and anti-leakage performance

6. Other Applications

Bonding agents, decorative mortar, polystyrene particle insulation mortar, cement-based powder coatings, gypsum-based products

IV. Application Method

1. Dry Powder Mixing (Recommended)

Thoroughly premix the polymer powder with cement, sand, fillers, HPMC and other additives mechanically for 3–5 minutes.

Add water as specified and mix at low speed for 3–5 minutes until a lump-free, uniform slurry is obtained.

Allow to mature for 5 minutes, then mix for another 1 minute before application.

2. Direct Water Dispersion (Small-scale Testing)

Slowly add polymer powder into room-temperature water under stirring to avoid agglomeration, until a uniform emulsion is formed.

3. Recommended Dosage (Percentage by weight of dry mix)

Interior wall putty: 1.5%–3.0%
Exterior wall putty: 3.5%–4.0%
Standard tile adhesive: 2.5%–3.0%
High-strength / flexible tile adhesive: 5.0%–6.0%
Insulation bonding / rendering mortar: 4.0%–5.0%
Self-leveling / repair mortar: 3.0%–5.0%

V. Safety & Protection

Toxicity: Non-toxic, odorless, non-corrosive; LD50 > 5000 mg/kg (oral, rat), meets environmental standards
Occupational protection: Wear dust mask, goggles and gloves during operation; avoid dust inhalation and contact with eyes and skin
Environmental impact: Non-bioaccumulative, wastewater degradable, not classified as hazardous waste

VI. Packaging, Storage & Transportation

Packaging: 25 kg/bag (paper-plastic composite bag with PE inner liner), sealed and moisture-proof
Storage: Store in cool, dry and ventilated area at 5–35℃, humidity <80%; protect from moisture, sunlight and high temperature
Shelf life: 12 months in unopened sealed package
Transportation: Non-hazardous chemical; protect from rain, moisture, direct sunlight and puncture by sharp objects

VII. Notes

Construction conditions: Ambient temperature ≥5℃ and ≤40℃, relative humidity <80%. Construction is prohibited below 5℃ as powder cannot form film normally.
Compatibility: Do not store or mix with strong acids or strong oxidants. Compatibility tests must be conducted before compounding with HPMC, water reducers or defoamers.
Slurry pot life: Use mixed slurry within 2 hours. Hardened slurry shall not be reused by adding water.
Curing requirements: Protect from rain, direct sunlight and frost within 24 hours after application to ensure full film formation.
Handling after opening: Use up as soon as possible after opening; reseal remaining product immediately to prevent moisture and caking.
