Emulsion acrylic- styrene copolymer polytex - 321

Product Describtion

Due to its excellent wetting properties, Polytex- 321 is widely used for production of interior/ exterior paints and construction mortar. The final dried film provides great adhesion on different types of surfaces such as plaster, cement and concrete.

Compatibility

Polymers: Polytex-321 is miscible with a wide range of nonionic and anionic aqueous polymers. It should be noted that most of the time dried film of the polymer blend has a cloudy appearance

Thickeners: Polytex-321 is compatible with Acrylic Acid-based, Polyvinyl alcohol ,Cellulose ethers and Poly urethane thickeners.

HP 800: polytex- 321 is compatible with HP- 800 additive. HP-800, formulated and manufactured in PolymerIran company, is a core- shell latex. Uniform particle size distribution of this additive results in uniform leveling and flow properties while the hard styrene shell improves the mechanical properties.

Plasticizers: Polytex-321 is compatible with Glycol ethers, Phethalate ester and Benzoate types.

Coalescence Agents: Polytex-321 is compatible with different types of Coalescence agents, such as Texanol, 402 solvent, Diethylene glycol monobutyl ether.

Fillers: Polytex- 321 is compatible with amorphous and crystalline carbonate, silica, clay, lithopone, talk, etc. Addition of Sodium polyphosphate will improve pigment wetting properties of the resin.

Explanations

While using Polytex-321, according to the usage, the film formation temperature can be decreased by coalescence agents and by using thickeners reach to the suitable viscosity. Using anti foam to the level of 0.1 to 0.3% when using this is necessary and in order to prevent of microorganisms attacks suitable preserver should be used. Using of glycols leads to resistance against freezing increases but altogether the film formation temperature will not decrease noticeably.

Storage

12 month from production date under standard conditions and away from direct sunlight and heat.

Safety tips

Material safety datasheets are available from PolymerIran company. While working with chemicals common safety measures must be observed. Skin, eye and mucous membrane irritation in prolonged contact with the acrylic polymer. Workplace should be sufficiently well-ventilated and protective clothes and goggles should be used.
