Product Description

Product Description

TJ 2220 fast curing resin

This epoxy resin is a special fast-curing cold mounting material, which consists of two components--resin and curing agent, both
in liquid state; At room temperature (25°C), mix the resin and curing agent at a ratio of 2:1 (weight ratio), and it can be cured into a colorless to light yellow transparent hard material after 30-60 minutes. It has superior adhesion, very low shrinkage and low tackiness. It can penetrate into the openings and through holes of the sample, and can maintain the edge and support of the sample to the greatest extent. It is suitable for use as a microsection curing adhesive in the electronics industry, and is suitable for cold mounting sample preparation of various micro metallographic samples.
