Fluoropolymer coating systems
The NC-400 nano coating dipping machine is an entry level dip coating system designed for processing nano coatings such as fluoropolymers.
The fluoropolymer coatings are normally blended with high cost fluorinated solvents for safety, reduction in transport costs and the environment. However, these solvents are highly volatile and can be lost from the system.
The nano coat system prevents these significant losses and allow coating of low and medium volume products in a safe, cost-effective way.
NC 400 nano coat system
The NC-400 dipping machine has the following features:
- Dip tank and basket system. A dipping tank and basket system for easy submersion of the product for conformal coating.
- Refrigerated system. A refrigerated sump for control and capture of the nano coating and the fluorinated solvents.
- Filtration. Integrated pumping and filter system for control of the quality of the nano coating.
- Unique refrigeration. Unique solid state refrigeration system to reduce evaporation losses.
- Built in redundancy. The solid state system tolerates failure of part of the cooling array and can continue working, saving both lost production time and expensive coating materials.
- Minimal losses. Built in dual cooling coils in the hold zone above the sump to further minimise losses due to the normal evaporation of the carrier solvent as the coated objects dry outside the machine.
- Manual or automated dipping. The dipping operation can be completed manually by the operator or optional automated dipping.
- Full compatibility. The NC-400 works with almost all current fluoro-polymer coating materials and fluorinated solvents from a variety of manufacturers.
