Water solubility: Typically has good water solubility and is capable of dissolving in water
at certain
temperatures to form transparent or translucent solutions.
Film-forming: It's is easy to form films, which usually have high tensile strength, abrasion
resistance
and transparency.
Adhesion:It has good adhesive properties, especially when bonded to hydrophilic materials
such as paper,
wood, etc.
Chemical stability: Generally have good chemical stability and are resistant to some common
chemicals.
Thermal Stability: It is stable over a range of temperatures, but excessive temperatures may
cause it to
decompose or lose some of its properties.
Insulation: It has good insulating
properties, making it
promising for a wide range of electrical and electronic applications.
In the textile industry, used as an additive, such as spinning liquid and textile slurry, to
improve the
strength and quality of textiles; it can also be used as a dispersant in the printing and
dyeing process
to improve the uniform dispersion of pigments and printing and dyeing effects;
In the paper industry, used for surface coating, bonding, and improving the strength of
paper;
In the coating industry, used to increase the adhesion and durability of coatings;
In the construction industry, it plays a significant role as an additive in cement, gypsum,
and concrete,
elevating the adhesive strength, toughness, and durability of the materials, thereby
enhancing the overall
quality of construction;
In the chemical industry, used as an emulsifier, dispersant, adhesive and binder to improve
the stability
and viscosity of chemical products. It can also be used in agriculture, daily medicine and
cosmetics.
Packaging: It is usually sealed and packaged in paper bags. The weights are 20 kg/bag,25 kg/bag,500 kg/bag, and 1000kg/bag. Storage: The recommended storage environment is dry, well-ventilated, with a temperature of 10~30℃, and the storage time should not exceed 12 months. Keep away from heat sources, moisture, or sunlight to prevent adsorption and deterioration. Avoid storing it with volatile chemicals to prevent adsorption and deterioration.
Correct Operation: When using it, ensure that correct operating methods and safety measures
are followed,
which includes properly measuring, mixing, and storing products to prevent any possible
chemical reactions
or accidental exposure.
Avoid inhalation and contact: Although these products themselves are not toxic, prolonged
inhalation of
their dust or direct contact with them may cause respiratory or skin irritation. Therefore,
appropriate
protective equipment such as gloves, masks, and goggles should be worn when operating.
Storage Conditions: Proper storage is also key to ensuring their safety. Please store it in
a dry,
ventilated place away from direct sunlight and high temperatures. In addition, ensure that
the product
packaging is intact and protected from moisture and contamination.
