Matrix resin hydraulic banjo fittings anti-static coating performance

The substrate formed of a resin skeleton, anti-static coating is the carrier of the electrically conductive filler. When the molecular weight of the matrix resin is too small

, The skeleton strength of the coating after film formation decreased, thereby affecting the physical properties of the coating; molecule is too large, the coating
The decrease in toughness, brittleness increases, usually the molecular weight of the matrix resin is preferably 5 ^ -7 000. When the surface of the matrix resin
Small, tension, is conducive to the resin wetting and dispersion of the filler particles, so that the indirect contact of the conductive particles to increase the total number
Add, so that the highest electrical conductivity of the coating is also increased. The matrix resin type conductivity of the coating has a very
The effect of a commonly used matrix resin for polyurethane acrylate, vinegar, an epoxy resin, etc.. In the selection of the matrix resin
Should be considered in the coating, drying method, was coated on the type of matrix resin in addition to enable the preparation of anti-
Electrostatic coating having a general coating properties, such as film-forming property, adhesion, durability, etc., should also electrically conductive filler
Has a certain affinity and wettability.
