What is the composition of ceramic tile adhesive ?

The material composition of ceramic tile bonding mortar usually include following materials:
The cement: cement is the important material , the cement is the main composition of tile adhesive .
The redispersible polymer powder (RDP): 
Redispersible polymer powders are polymer emulsions which have been converted by a series of process such as high temperatures and pressures, spray drying and surface treatment to powdered thermoplastic resin materials. When mixed with water, these powdered organic binders can redisperse in water back into new emulsions with essentially identical properties to the original copolymer emulsions.
The VAE can improve the bonding strength of all the substrate,increase tensile strength ,reduce elastic modulus , increase water retention rate, improve workability, reduce permeability, etc.
The sand: sand is the important material in the construction materials , it as aggregate and adjust the consistency of bond mortar, so its particle size is very important;
The HPMC cellulose
Hydroxypropyl methylcellulose (HPMC) is a nonionic cellulose ether prepared by a series of chemical processing using natural polymer materials as raw materials.
Product properties:
1.Water Retention: The water retention will be enhanced, which is helpful with such problems as cement or gypsum construction material drying too fast and poor hardening or cracking due to insufficient hydration.
2.Operationality: It can enhance the plasticity of mortar and improve the coating efficiency in construction projects.
3.Adhesivity: It can make mortar attach to base material better since the plasticity of mortar is enhanced.
4.Slip Resistance: It can prevent slipping problem between mortar and the base material in construction project as a result of its thickening effect.
it as a thickener and bonding mortar to maintain water, and give bonding mortar workability good (mortar thin layer construction process thin, and easy to lose water in cement and water reaction, such as evaporation, or absorption of substrate and ceramic tile);
Other functional additives.
