Raw materials for can and packaging coatings — micron-thin films that survive forming and sterilisation.
Can coatings are applied at a few microns and then have to endure everything: deep drawing and seaming without cracking, sterilisation without discolouration, contact with the filling without migration. Stoving times of seconds on fast lines demand additives that deliver flow and air release instantly — and slip additives that let the can run through the filling line.
We supply BYK levelling, slip and air release additives, melamine and benzoguanamine crosslinkers from Prefere Melamines and polyester resins from Synres — with advice on the food-contact framework of the packaging sector.
Typical defects — and where the solution lies
Levelling has to happen in seconds
Design levelling additives for short stoving windows on fast lines. — Surface additives →
Cans do not run cleanly through the filling line
Adjust the slip of the exterior coating with wax additives. — Wax additives →
Crosslinking with food-contact requirements
Choose melamine and benzoguanamine crosslinkers for flexibility and sterilisation resistance. — Amino crosslinkers (melamine) →
Microfoam in films of a few micrometres
Air release for the thinnest wet films — bubbles that cannot escape become pores. — Defoamers →
