MetaLine Series 500 consists out of the following 4 elastomeric coating types:

• MetaLine 560, soft, 60 Shore A
• MetaLine 580, semi-soft, 80 Shore A
• MetaLine 590, semi-hard, 90 Shore A
• MetaLine 598, hard, 98 Shore A

The main field of application is the surface optimization of vibratory feeding devices like feederbowls in stepped, conical, or cylindrical designs. The coatings also support repair and surface protection against impact, shock, and wear.

Approvals from leading European automation, bowlfeeder, and robotic-gripper manufacturers.

Processing of MetaLine Series 500 is based on tools usually used for high-end paint spraying. After mixing, an airless spray system is used to apply the material in thin layers each 500 µm (20 mils) at the most. The required spray pressure amounts to approximately 120 bar (1,750 psi). For ultra-small applications a mastic gun might be used as well but is not recommended. The high dilution ratio and low gun output limit efficiency, while air-dispersion leads to porosity of the coating system.

The rubber-like surface reacts thermally and electrically insulating and can be machined by most processes. Temperature resistance up to 100 °C (212 °F) dry. Drug and food safety according to FDA and EU approval available.

MetaLine Series 500 offers intensive additivation possibilities to adapt coating characteristics:

• Hardness (durometer)
• Surface stiction
• Smoothness / surface texture
• Electrical conductivity / anti-static
• Color
• Film thickness
