Single-component disinfectant HQ-2021

Single-component disinfectant HQ-2021

Product Introduction:

HQ-2021 is a water-based liquid broad-spectrum biocidal preservative based on monovalent salt isothiazolinone. It delivers remarkable inhibitory effect on common bacteria, fungi and algae in water, and can effectively prevent microbial contamination even at low dosage.

Application Fields:

Coatings & inks, adhesives & emulsions, water treatment systems, water-based putty, waterproof coatings, leather treatment solutions, paper sizing agents, daily chemicals and other industries.

Usage & Dosage:

The recommended dosage is 0.2–0.5%, subject to emulsion types and preservation requirements of finished products. Check the pH value of the system before use, and avoid residual reducing substances and nucleophilic substances in the system.

Details

Physical & Chemical Indexes:

Appearance: Light yellow transparent liquid with slight characteristic odor

pH (25℃, 1% aqueous solution): 2.0±4.0

Density (20℃, g/cm³): 1.10±0.10

Solubility (25℃): Soluble in water, insoluble in non-polar organic solvents such as benzene and toluene

Core Active Substances: Monovalent salt isothiazolinone (CMI, MI)

Performance Features:

It can effectively inhibit common bacteria, fungi and algae in water and prevent microbial contamination at low dosage;

Formaldehyde-free, zero VOC (volatile organic compounds), low irritation, readily biodegradable in the environment without cumulative pollution;

It hardly causes flocculation and is foam-free, which helps stabilize production processes and guarantee finished product quality;

Its core active ingredient monovalent salt isothiazolinone is an efficient mainstream biocide worldwide with favorable chemical stability and high bactericidal efficiency;

It has poorer stability compared with divalent salt isothiazolinone, sensitive to temperature and pH, carries higher risk of skin sensitization and weak anti-interference capacity.

 

Packaging, Storage & Transportation:

Packed in 25 KG / 1000 KG plastic drums. The shelf life is 24 months from the production date when stored in unopened original containers at a temperature ranging from 5℃ to 40℃.
