What is polyamide curing agent 3115?
Polyamide curing agent 3115 is a high molecular weight epoxy resin curing agent with the following characteristics and application fields:
-* * Characteristics**
-High viscosity: Its viscosity is ≥ 100000pps at 25 ℃, appearing as a light yellow or orange red transparent viscous liquid.
-* * Excellent Performance * *: It has excellent water resistance, corrosion resistance, bonding performance, good wettability to color and substrate, and excellent chemical resistance.
-* * Longer applicable period * *: After mixing with epoxy resin, it has a longer applicable period and can meet certain construction operation time requirements.
-Low comprehensive cost: Stable price, good compatibility with resin, no need for curing, can reduce usage costs and operational difficulties.
-* * Technical indicators**
-Amine value: 200-220mgKOH/g.
-Density: 0.97 ± 0.01 at 25 ℃.
-Chromaticity: Orange red.
-* * Active hydrogen equivalent * *: 175.
-Recommended dosage: For liquid epoxy resin (EEW=190), the recommended dosage per 100 parts of epoxy resin is 100: （80 - 100）。
-* * Application Fields**
-Ship anti-corrosion coating: It can provide good anti-corrosion protection for ships and resist the erosion of seawater, sea breeze, etc.
-Pipeline anti-corrosion: It can be used for anti-corrosion coating on the surface of pipelines to extend their service life.
-* * Bonding, joint filling, grouting, etc. * *: It has good bonding performance and can be used for bonding, joint filling, and grouting operations of various materials, such as repairing and sealing building structures.
