epoxy hardener MD315

MD315 is a solvent-free epoxy hardener based on Cashew Nut Shell Liquid(CNSL) with outstanding anti-corrosion performance.

MD315 is a solvent-free phenalkamine epoxy hardener based on Cashew Nut Shell Liquid (CNSL). It can cure at room and low temperature (≤-5°C). Also it is moisture tolerant while curing and outstanding in anticorrosion performance, excellent in mechanical property, friendly to environment etc. In addition, it has high performance-cost ratio.It is an excellent substitute of polyamide epoxy hardener.

 

MD315 can be applied in fields of petroleum pipelines, mechanical equipments, storage tanks, steel structure, marine anticorrosion, industrial flooring etc:

1.various of heavy duty epoxy coatings;

2.industrial paintings;

3.epoxy flooring coatings;

4.composite materials;

5.adhesives etc.

Specifications as below:
