Characteristic:
1. Water-soluble, non-ionic cellulose cellulose ether
2. Odorless, tasteless, non-toxic, white powder
3. Dissolved in cold water, forming a clear or slightly solution
4. Properties of thickening, binding, dispersing, emulsifying, film-forming, suspension, adsorption, gel, surface activity, water retention and protective colloid.
1. Construction industry: As water and sediment slurry agent, retarder so that mortar with pump-delivery. In plaster, gypsum material, putty powder or other building materials as binders, to improve the smearing and prolong the operation of time. Used as paste tiles, marble, plastic decoration, paste enhancer, but also can reduce the amount of cement. The water retention properties of hydroxypropyl methyl cellulose make the slurry not crack after smearing and enhance the strength after hardening.
2. Paint industry: In the paint industry as thickener, dispersants, and stabilizers, in water or organic solvents have good miscibility. As a paint stripping agent.
3. Plastic: As forming release agent, softening agent, lubricant and so on.
4. Other: This product is also widely used in leather, paper products industry, fruit and vegetable preservation and textile industry.
Usage:
construction mortar, plaster mortar,
putty water-resistant putty,
interface agent,
exterior wall adhesive putty,
ceramic tile adhesive,
flashing compound,
self-levering material,
thickening agent.
