Product Description

Product Description

3296A/BS/BW is a fast-curing epoxy resin system, consisting of an epoxy resin part 3296A and a modified amine hardener part 3296BS and BW. It has the advantages of low viscosity, fast defoaming, fast curing, and can be adapted to the curing  requirements under different temperature environments. The final product is light and transparent, with good gloss and excellent performance. It is suitable for the repair and potting of parts.

Features

TYPICAL PROPERTIES OF SYSTEM COMPONETNS

3296A Liquid Epoxy Resin

Appearance Colorless transparent liquid

Viscosity(25ºC, cps)  2300-2800

Density(25ºC, g/cm³)  1.1-1.2

Epoxide equivalent(g/mol)  175-185

Shelf life(10ºC  sealed, month) 24

3296A liquid epoxy resin must be stored at room temperature.
The vessel should be kept sealed. If find crystallization or precipitation, it is recommended to heat the resin to 60-70°C and stir or shake it properly.

3296BS/BW/BF liquid amine curing agent must be stored at
room temperature. The vessel should be kept sealed. It is very sensitive to water and temperature. Storage in a high humidity environment will greatly affect the reactivity of the system material and the final performance.

The mixing ratio of the configuration must be strictly in accordance with the instructions. Add a small amount or a large amount of curing agent will not slow down or accelerate the reaction rate, but it can lead to an unchangeable incompletely cured state of the cured product. The resin and the curing agent must be completely mixed until there is no fibrous or turbid state in the mixed liquid, paying special attention to uneven mixing on the wall and the bottom of the vessel
