FAQS
When water is added to the dry mix mortar, the VAE copolymer powder becomes a dispersion and forms a film upon drying. This film promotes elasticity and adhesion. ADHES® Redispersible polymer powders are classified into highly flexibility with low adhesion, rigid with high adhesion, neutral with standard adhesion(both adhesion and flexibility). Water is added to some powders to impart hydrophobic characteristics to the material.
Vinyl Acetate-Ethylene Polymers (VAE) --These powders blend the flexibility of ethylene and the adhesion of vinyl acetate, leading to many economic and ecological benefits without affecting performance.
They offer several benefits, including excellent cohesion, flexibility, good low-temperature film and variable glass transition temperature. They also show great adhesion to certain substrates like plastics and wood.
Ethylene-vinyl acetate-acrylate terpolymer-- These polymer powder show very good adhesion properties. Its film has good flexibility, strong plasticity, strong wear resistance and deformation ability.
Styrene-acrylate copolymer--The polymer powder has extremely strong anti-saponification ability. It has good adhesion to various substrates such as polystyrene foam board, mineral wool board, etc.
Redispersible polymer powders have numerous applications across various industries. They are widely used in:
· Construction adhesives
· C1 C2 Tile adhesives
· Joint mortars
· External wall putty
· Building binders
· Filling compositions like concrete repair joints, crack isolation membranes, and waterproofing membrane applications.
The glass-transition temperature refers to the temperature at which polymers will be converted from an elastic state to a glassy state, expressed by Tg. When the temperature is higher than Tg, the material is rubber-like in behavior and generates the elastic deformation under load; when the temperature is lower than Tg, the material is glass-like in behavior and prone to brittle failure. Usually if Tg is high, the hardness after film formation is also high, rigidity good and heat resistance is good; otherwise, if Tg is low, the hardness after film formation decreases, but the elasticity and flexibility are good.
In preparation of dry-mixed mortar, redispersible polymer powders of different Tg values should be selected according to the purpose, operating environment and base material of mortar. For example, in the preparation of tile adhesives and crack-resistant plastering mortar, two main factors should usually be considered. One is high adhesion; the other is sufficient flexibility and capacity of deformation resistance. Therefore, select the polymer powder with low Tg, low temperature and good flexibility.
