Re-dispersible Emulsion
The Re-dispersible emulsion is an emulsion obtained by specific emulsion polymerization
and stabilization, which consists of polymer emulsion, protective colloid, defoamer,
antifreeze, preservative filler, etc. It is fluid and can be used directly as an
additive. The Re-dispersible emulsion can be re-dispersed in water after drying to form
a stable emulsion dispersion system. The Re-dispersible emulsion has good adhesion,
water resistance, weather resistance, and workability, so it is widely used in interior
and exterior wall coatings, dry mortar, waterproof materials, and other fields. Adding
it to various building materials can improve the performance of the materials and
increase construction efficiency.
What are the properties of Re-dispersible Emulsion?
Redispersibility: After drying, it is easily re-dispersed in water to form a stable
emulsion system, which can be mixed with other materials to form a uniform and
consistent mixture.
High bonding power: Emulsions have strong adhesive properties that enable them to adhere
effectively to a wide range of surfaces and substrates, helping to enhance the adhesion
and cohesion of coatings, adhesives, and other construction materials.
Durability and Weatherability: Redispersible emulsions improve the durability and
wearability of coatings and building materials, preventing them from cracking, peeling,
and fading.
Flexible and deformable: The emulsion's polymer structure is flexible and deformable,
helping to reduce stress and cracking and improving the material's overall
performance.
Compatibility: Dispersible emulsions are compatible with a wide range of materials,
including cement, fillers, pigments, and other additives.
Environmentally friendly: Emulsions are often formulated with environmentally friendly
ingredients and contain no harmful substances. It also helps to reduce waste during the
manufacturing process.
What is Re-dispersible Emulsion used for?
Construction: Re-dispersible emulsion can be used as an additive to enhance the bond
strength, water resistance, weatherability, and durability of mortar, concrete, and
other construction materials.
Coatings and Adhesives: As a key ingredient in coatings and adhesives, Re-dispersible
emulsion enhances the adhesion and hiding power of coatings and improves the bonding
strength and durability of adhesives to meet better the needs of various applications,
such as indoor and outdoor wall decorations, and wood bonding.
Fibre products: Re-dispersible emulsion can also be used in the manufacture of fiber
products, such as textiles and nonwovens. By adding emulsion, the softness, elasticity,
and durability of fiber products can be improved, and their usability enhanced.
Other fields: In addition, Re-dispersible emulsion also has a wide range of applications
in paper coating, leather treatment, ink manufacturing and other fields due to its good
compatibility and processability.
How is Re-dispersible Emulsion produced?
Mix monomers such as ethylene, vinyl acetate, and acrylic esters with emulsifiers, water,
and initiators, and then the emulsion is polymerized at specific temperatures and
pressures. By controlling the polymerization conditions (e.g., temperature, pressure,
stirring speed, etc.), the monomers are gradually converted into polymers, and a stable
suspension of emulsion particles is formed. After the polymerization is completed, the
emulsion is post-treated, including pH adjustment, neutralization, removal of unreacted
monomers and oligomers, the addition of stabilizers and functional additives, etc., in
order to improve the stability of the emulsion and the performance of the final product.
How is Re-dispersible Emulsion packaged and stored ?
Packaging: Use packaging materials with good sealing and moisture-proof properties, such
as plastic drums, metal drums, aluminum foil bags, etc., to prevent the entry of outside
air and moisture.
Storage: The Re-dispersible emulsion should be stored in a dry, cool, and
well-ventilated place, avoiding direct sunlight and a high-temperature
environment.
Avoid its contact with dust and harmful substances to avoid chemical reactions.
Re-dispersible emulsions stored for a long time should be checked regularly for
condition. If the package is broken, the emulsion color changes, there is a strange
smell, etc., it should be dealt with in time to avoid use.
What are the safety precautions for the use of Re-dispersible Emulsion?
Re-dispersible emulsion itself is a non-toxic, odorless, non-polluting, and
environmentally friendly product, but can pose potential health risks if toxic
substances are added during the manufacturing process or if proper safety practices are
not followed during use.
Wear appropriate protective equipment such as gloves and glasses when using lotion to
avoid skin contact and inhalation.
In case of inadvertent contact with skin or eyes, flush immediately with water and seek
medical help.
