New product, buy Double epoxy anticorrosive powder coating (External) on China Suppliers Mobile

Product Details

Introduction: This double epoxy powder adopts many kinds of function of epoxy resin, curing agent, both bottom coating and other anti-corrosion epoxy powder coating have excellent anticorrosion performance, external coating stand out protective properties on the basis of corrosion, can be widely used in more stringent corrosion environment, especially especially traversing pipeline for mountains, rivers and hills region.

Feature:

1. Very good adhesion with the substrate and epoxy.

2. Strong permeability and corrosion resistance

3. The coating has excellent high temperature cathodic disbonding resistance.

4. High surface hardness, strong coating density, good ability to resist plant roots puncture
