Product Overview
Traditionally, green sand moulds have not generally been coated. However, the growing need for an effective coating solution to improve cast surface quality has led to the development of HARDCOTE SF800. Specifically designed for high-speed production lines commonly used in the manufacture of grey and ductile iron castings, this innovative product integrates seamlessly into the production environment, enabling the surface coating of moulds without compromising productivity.
Key Benefits
- Water based coating
- Non-hazardous
- Easy and fast application
- No need for drying – pouring within 10 minutes
- High refractoriness
- Great performance against mould erosion
- No metal penetration – improved casting quality
HARDCOTE SF800 green sand coatings provides an efficient, cost effective and environmentally responsible solution for improving the surface finish of green sand moulds. Unlike traditional refractory coatings which require drying after application or use solvents that evolve VOC’s, HARDCOTE SF800 is a newly developed water-based product. It is applied as a fine spray to the green sand mould surface and rapidly forms a protective layer that does not require drying and therefore does not disrupt the production process.
