N-Propanol is a common solvent in industry and daily life.It is volatile and combustible and can be mixed uniformly with water and a variety of solvents.It is often used as an auxiliary ingredient in cleaning circuit boards, diluting paint and cosmetics.
The main product characteristics of it is as below
Excellent coupling ability
It is not only completely miscible with water, but also miscible with most organic solvents, making it an excellent coupling solvent that can be used to adjust the solubility of aqueous systems or improve the hydrophilicity of oily systems.
Moderate evaporation rate
Boiling point higher than ethanol and lower than butanol. The moderate evaporation rate is beneficial for construction leveling and improves construction efficiency.
Good permeability
The surface tension is about 23.7mN/m(20℃) , much lower than water (72.8mN/m), what can help quickly wet and penetrate complex surfaces and micro gaps, improving efficiency and uniformity in cleaning and coating.
Low viscosity
The viscosity is about 2.3mPa·s (20℃) , similar as ethanol, and shows excellent fluidity. In the formula, it can effectively reduce the overall viscosity of the system, improve spraying and leveling performance, and is easy to pump and mix
Application
Coatings and inks
As a solvent or co solvent, it is used in gravure printing inks, coatings, and other fields to improve resin solubility, adjust drying speed, and leveling properties.
Industrial and Electronic Cleaning
Used to prepare cleaning agents for precision instruments, metal components, and circuit boards (PCBs), utilizing their ability to dissolve grease and rosin flux, with low residue after volatilization.
Chemical synthesis and pharmaceuticals
As solvents or extractants in organic synthesis reactions, as well as solvents in the pharmaceutical industry, it is necessary to strictly control the residues in the final product.
Daily chemicals
As a solvent or coupling agent, it's widely used in cosmetics, personal care products, and household cleaning agents
Package & Storage
Package
160-200kg drum, 1000kg IBC drum
Storage
Stored in a cool, ventilated warehouse, must keep the temperature under 30 ℃.
Stay away from fire and heating.
Keep drum sealed. It should be stored separately from oxidants, acids, halogens, and edible chemicals, and avoid mixing storage.
FAQ
Q: Why is it often used as a solvent for printer ink?
A: Because n-Propanol dissolves the pigment quickly, the volatilization rate is moderate.This can ensure that the printing pattern is clear and not stained, so it is often used in the high speed printing process of newspapers and magazines.
Q: What can it do in leather care agents?
A:Propanol-1 can quickly penetrate the leather fiber, help nourishing ingredients evenly distributed, while inhibiting mold growth, prolonging the service life of leather goods.
Q: Does it corrode the metal?
A: It is not corrosive to ordinary metals (iron, aluminum, stainless steel).However, long-term contact with copper products may cause discoloration of the surface. It is recommended to dry it after use.
Q: What role can it play in the paint?
A: As a film-forming additive, it can adjust the drying speed of paint, make wall paint easier to flow and reduce brush marks. It is commonly used in indoor latex paint formula.
Q: Will glass cleaner containing propanol fog up the mirror?
A: No, its rapid evaporation characteristics can reduce water vapor residue, and the added anti-static components can delay dust attachment, keep the mirror clear for a longer time.
