Technical Specifications of Liquid Caustic Soda NaOH 45%

The table below summarizes the standard technical specifications of 45% liquid caustic soda distributed directly by Loc Thien Chemicals. The actual active ingredient concentration is transparently confirmed on the COA certificate accompanying each shipment.

When to Choose Liquid Caustic Soda NaOH 45% Instead of 32% or 48–50%?

Choosing the appropriate concentration of liquid caustic soda directly impacts transportation costs, storage tank capacity, and pump system lifespan. The 45% NaOH solution represents an optimal balance between pure alkali content and storage stability under real-world weather conditions.

Compared to 32% liquid caustic soda, the 45% solution helps businesses save storage tank volume and reduce transportation costs per unit of alkali. Compared to 48% NaOH or 50% sodium hydroxide solution, the 45% concentration has a lower freezing point, reducing pipe freezing in winter and ensuring smooth pump operation without requiring expensive heating systems.

Customers can refer to more detailed information in the Loc Thien NaOH catalog to select the most suitable concentration before finalizing orders.

What to Note During Dilution, Pumping, and Storage of NaOH 45%?

NaOH 45% is a highly corrosive alkali chemical that generates significant heat when dissolved in water. The mandatory safety principle is to slowly add caustic soda to water, never pour water into concentrated caustic soda tanks to avoid dangerous chemical splashing.

Operators must wear full PPE, including safety goggles, thick rubber gloves, respirators, and rubber boots. Storage tanks should be made of FRP, PVC, HDPE, or stainless steel. In water treatment plants, NaOH 45% is often combined with 31% PAC solution to optimize pH for coagulation. To neutralize excess alkali, operators use chemicals from the industrial acids catalog to bring wastewater to safe standard levels.

What Industries and Purposes Use NaOH 45%?

Liquid caustic soda NaOH 45% is an essential industrial alkali material, playing a crucial role in the operational processes of many key manufacturing industries:

1. Wastewater Treatment and pH Neutralization (ETP / WTP):
NaOH 45% solution is dosed into reaction tanks to raise pH, neutralize acidic wastewater, and create an alkaline environment for heavy metal precipitation. Technical teams often combine liquid caustic soda with products from the water treatment chemicals catalog to accelerate coagulation. When sending RFQs, procurement departments should provide clear discharge flow rates, input pH, tank specifications, and Industrial Zone locations for suitable delivery plans.

2. Textile Dyeing and Fabric Finishing:
In textile dyeing plants, 45% liquid caustic soda is used to clean oils from fibers, mercerize fibers to increase durability and dye uptake. The stable 45% concentration helps dye baths maintain standard pH, avoiding color discrepancies between fabric batches. Businesses sourcing materials from the textile dyeing chemicals catalog should specify monthly consumption volumes and packaging requirements for the best bulk pricing policies.

3. Paper, Pulp, and Carton Packaging Production:
NaOH 45% participates in wood pulp cooking to separate cellulose fibers from lignin, while also bleaching recycled pulp and cleaning paper machine pipelines. When ordering from the paper & packaging chemicals catalog, procurement departments should request COA confirmation of batch concentration and agree on safe tank filling procedures.

4. Industrial Detergent and Soap Production:
45% liquid caustic soda performs saponification reactions with fats to produce industrial detergents, floor cleaning solutions, and degreasers. The 45% solution saves dissolution time and reduces localized heat generation in mixing tanks. When sending RFQs to the industrial chemicals catalog, businesses should clarify batch mixing scales and periodic delivery plans.

5. Metal Surface Cleaning and Electroplating:
In metalworking and electroplating, 45% NaOH solution is diluted into hot alkaline cleaning baths to remove lubricating oils and cutting fluids from parts before plating or powder coating, enhancing plating adhesion without damaging metal surfaces. Bulk customers should specify Industrial Zone locations, can, drum, or IBC tank requirements when requesting quotes.

6. Ion Exchange Resin Regeneration in RO Water Filtration:
Diluted NaOH 45% solution is used to rinse and regenerate anion exchange resins in RO water filtration systems, demineralizing boiler feedwater. The alkalization reaction removes accumulated acid groups, restoring resin ion exchange capacity. Procurement departments should determine resin volumes to select optimal packaging solutions.

7. CIP Pipeline Cleaning in Food and Seafood Processing Plants:
In seafood processing and food plants, 45% NaOH solution is used in closed-loop cleaning-in-place (CIP) processes to remove protein films and residual fats from pipelines and storage tanks. Loc Thien Chemicals distributes products meeting industrial standards with transparent COA certificates. When submitting RFQs, procurement departments should specify internal technical requirements for detailed consultations.

Frequently Asked Questions About Liquid Caustic Soda NaOH 45% (FAQ)

Does NaOH 45% Concentration Fluctuate with Environmental Temperature?

The concentration of 45% liquid caustic soda remains highly stable under standard storage conditions. When environmental temperatures drop significantly in winter, the solution may slightly thicken, but the active alkali concentration remains unchanged according to the COA certificate. Factories only need to ensure sealed storage tanks and properly insulated pump lines.

Does Loc Thien Chemicals Support Tanker Truck Delivery of NaOH 45% to Stations?

Loc Thien Chemicals owns specialized tanker trucks ranging from 10 to 30 tons, along with drum-carrying trucks, ready to deliver 45% liquid caustic soda directly to factory tanks nationwide. Drivers are professionally trained in chemical safety, ensuring completely sealed pumping operations, absolute safety, and on-time delivery as committed.

Is a Heating System Required for Storing Liquid Caustic Soda NaOH 45% in Winter?

Compared to 50% caustic soda solution, 45% liquid caustic soda has a significantly lower freezing point, reducing the risk of freezing or crystallization under normal weather conditions in Vietnam. Therefore, most plants do not need to invest in expensive heating coil systems for storage tanks, saving electricity and maintenance costs throughout operations.

What Information Do Businesses Need to Provide for Fastest Bulk NaOH 45% Quotes?

To receive accurate and competitive bulk NaOH 45% quotes from Loc Thien Chemicals, customers should provide estimated volume requirements, desired packaging (drums, IBC tanks, or tanker trucks), and delivery locations. The consulting team will prepare comprehensive cost plans including transportation fees and respond with RFQs within 2 working hours.
