What is Polyamine Epoxy Hardener
APPLICATION
This product is suitable for industrial floor coatings, tank coatings, solvent-free coatings, concrete adhesives, etc. It is used in the formulation of compositions that cure at room temperature, such as
Benefits
• Low viscosity • Excellent surface appearance • Provides good mechanical performance • Good balance between hardness and flexibility
Security, Storage and Transport
Polyamine epoxy hardener is slightly hygroscopic and should be stored at room temperature in conditions where moisture will be excluded. the original containers were kept tightly closed. Under these conditions, the shelf life must be at least two years from the date of certification.
Properties of polyamine hardener
Polyamine hardener is a chemical substance used to cure or cure epoxy resins. These types of hardeners are obtained by reacting amines with acids and are generally divided into two categories: aliphatic polyamine hardeners and aromatic polyamine hardeners. After the polyamine hardener is added to the epoxy resin, a chemical reaction occurs between these two materials, which cures the resin. This reaction is exothermic and can increase the temperature of the resin and hardener mixture. The cure speed of polyamine hardeners varies depending on the type. Hardeners with high cure rates are suitable for applications that require fast cure. On the other hand, hardeners with low cure rates are used in cases where performance is preferred over cure speed (applications that require more cure time).
Polyamine hardener properties
The properties of polyamine hardener are as follows.
Polyamine hardeners have a sharp and irritating odor.
Polyamine hardeners come in different viscosities: some are liquids, some are solids.
These hardeners are poisonous and can cause irritation and allergy if in contact with skin, eyes or inhaled.
Polyamine hardener applications
Polyamine hardener is widely used in industry, including. Polyamine hardener is the most important material for curing epoxy resins. Epoxy resins are widely used in various industries such as glue, paint and coatings, composites, flooring and insulation. Polyamine hardener is also used in other applications such as water treatment, leather making and pharmaceuticals.
Storage conditions
Store polyamine hardener in original container and close the cap tightly. Store hardener at a temperature between 5 and 25 degrees Celsius. Prevent hardener from freezing. Do not use hardener after expiration date. Store hardener in a cool, dry and ventilated place. Avoid exposure to heat, direct sunlight or moisture.
Safety tips
Polyamine hardener can be toxic, corrosive and irritating, so care should be taken when working with it. Here are some important safety tips for polyamine hardeners. Wear gloves, eyewear and appropriate protective clothing. Avoid direct contact of the hardener with skin and eyes. Do not mix the hardener with other chemicals unless specifically instructed to do so. Mixing the wrong chemicals can lead to dangerous reactions. If the hardener comes into contact with your skin or eyes, wash the area immediately with plenty of water and seek medical attention if necessary. Store the hardener out of reach of children and animals. Use the hardener only in well-ventilated areas. Avoid eating, drinking or smoking while working with the hardener. Wash your hands thoroughly with soap and water after working with the hardener.
