JTB-400PF is a hydroxypropyl methylcellulose ether (HPMC).
JTB-4W/10W/20W are hydroxypropyl methylcellulose ethers (HPMC) that are classified into 4W, 10W, and 20W based on their viscosity.
This product functions as a thickener, suspender, thixotropic agent , and water-retaining agent in low-viscosity fluid mortar systems . It possesses the following characteristics and advantages.
For Production:
• Its specific particle size allows it to dissolve quickly and prevents clumping.
For Formulation:
• Stable performance and compatible with all conventional inorganic binders
For Construction:
• It can improve water retention and prevent sagging in self-leveling mortar, and will not form architectural ripples when the coating is thick.
This product is suitable for various fluid mortars and cement concretes, especially for surface cement-based self-leveling mortars and gypsum self-leveling mortars, and is suitable for water
retention, thickening, and suspension modification.
The recommended dosage of this product in various systems is 0.1 to 3.0‰ of the cementitious material. The optimal dosage needs to be determined through testing.
This product is packaged in paper bags, 25kg/bag (larger bags can also be provided upon special requirements).
This product is recommended to be stored in an environment of 0~30℃ and used within 12 months; there is a risk of clumping.
