Propropanol NPA (n-Propanol) is an aerobic solvent that is clear and transparent and typically smells of alcohol. As a form of Primary Alcohol, it has excellent power balance and solubility, is fully fusion with water and is soluble in most organic solvents. In industrial applications, NPA is an efficient option for improving product stability and processing performance.
In the electronics industry,NPA plays a crucial role, especially in high-precision production such as semi-conductor sealing, printing circuit board (PCB) assembly and photo panels manufacturingI don't know. NPA has a very low metal ion to PPT level, with a water level of PPM and meeting the Particle cleanliness requirement, usually as a formulation for high purity washing or photoresistor dilution, with core values balancing "solvability" with "dry speed".

Solvability
| Category | Dissolve the object | Solubility | Electronic/industrial applications |
| Water system | Water | Full fusion | Water can be mixed in any proportion and adapted to the water detergent. |
| Polar solvent | ethanol, isopropanol, acetone | Full fusion | An excellent formulation compatibility, which is often adjusted as a consolant. |
| Non-polar solvent | Fats and aromatics. | Partially to Full Dissolve | It is soluble with most of the organic solvents and helps to clear the complex oil pollution. |
| Natural resin | Worm and pine (Rosin) | Excellent. | The electron industry is used to dissolveWelding (Flux) In the pine fragrance. |
| Synthetic resin | Polyethyleneol i.e. formaldehyde (PVB) | Excellent. | Inks and coatings are commonly used to provide excellent membrane stabilization. |
| Neptunoids | Ethylene, nitrite | Good. | Increase the fluidity of the paint and prevent the whitening of the paint. |
| Grease | Vegetable oil, mineral oil | Good. | Industrial cleaning can effectively defaminate and remove metal surface oils. |
| Dust/paint | Multi-ethanol soluble dyes | Excellent. | Ensure that the ink formula is coloured and does not produce sanctuaries. |
Advantages
Relatively stable.Wave rate
The NPA is about 0.6 times faster than the IPA (isopropanol), which is a medium-speed-split solvent. A more stable evaporation process prevents surface temperature from falling and water condensing in the air from "water spots" or "painted membranes" on the surface of the base plate. In the case of automatic spraying or printing, NPA can keep wet for longer and provide a better levelling (Leveling) to make the coating more even.
Powerful penetration and cleansing
Low surface tension: NPA has a very low surface tension (approximately 23.8 mN/m) that can easily penetrate the micro-scale component cracks, dissolves thoroughly and removes hidden welding, saline or processed oil.
High solubility parameters: NPA has a higher solubility than ethanol for the cedar and synthetic resin that is common in the electron industry, ensuring that the cleaning base surface reachesIon contamination.The strict criteria.
Height Formula Compatibility
Good solubility: Perfectly mixed with water, ols, ethers, esters and a variety of carbon hydrate solvents are the preferred ingredients for adjusting high performance washing, photoretardants (EBR) and industrial ink.
Leather compatibility: especially membrane substances such as PVB (polyethylene vinyl vinyl vinyl) and Ethylene, which are suitable for solubility, can increase the adhesiveness and stability of paint.
Excellent chemical stability and solubility
It is fully soluble with most organic solvents, such as alcohol, ether, benzene, etc., making formulations more dynamic and chemically stable, easily stored and transported over long distances.
Safety and damage reduction
Safety: NPA flashpoints (about 23°C) are higher than ethanol and IPAs, and can effectively reduce fire and explosive risks in storage, transport and large-scale cycling systems, meeting the requirements of modern plants for safe production.
Reducing the waste of solvents: Natural damage in the open cleaning tanks is much lower than IPA because of the right speed of the process, which can effectively reduce the cost of raw materials acquisition and reduce emissions of VOCs.

Security & Save Proposal
Save Condition
- Environment Temperature Control: Should be stored in a cool, dry, well-ventilated fire warehouse. Distance from sources of fire, heat sources (e.g. direct sunlight or high temperature walls).
- Packaging requirements: Packagings must be kept intact and sealed to prevent water absorption (nPA is water-friendly) and solution. It is recommended to use carbon steel drums that are not coated with steel drums or that are protected against corruption.
- Ban on appliance isolation: Co-exist with stronger oxidizers (e.g., high acrylic acids, peroxides), acids and molybdenums are strictly prohibited in order to prevent a dramatic chemical reaction.
- (b) The storage area should be equipped with electrostatic and blast-proof lighting systems.
Operate environmental and operational advice
- Ventilation systems: Operating the environment with a local ventilator or a good overall ventilation to ensure that the NPA is below the legal standard in the air.
- Personal protection (PPE):
- Respiratory protection: If the environment is more dense, it should be equipped with an ethanol filter.
- Hand protection: suggest a Nitrile or chemical protective gloves.
- Eye protection: With chemical protection spray safety glasses.
- Safe Operating Standards
- It is strictly forbidden to smoke, eat or use open fire on the ground.
- The speed of currents should be controlled when filled or dumped, and it should do so to prevent static accumulation from sparkling.
- The operation should be followed by a thorough hand-washing and replacement of contaminated clothing.
Transport advice
- Transport regulations: IMDG, IATA, and national road transport security laws.
- UN Number: UN 1274
- Transport name: n-propanol (n-PROPANOL)
- Packing type: II (medium-risk)
- Vehicle requirements: Transport vehicles should be equipped with visible dangerous brands, fire-fighting equipment (e.g. dry powder or soluble foam fire extinguishers) and links.
- In the summer, transport should avoid high temperatures (recommended for morning or evening) and be careful of sunscreening.
