Define UV Curing Technology

Coatings, inks and adhesives that are cured using light as the catalyst. Liquid plastic that cures with light.

Chemistry & Formulation of UV/EB

What are the differences between Conventional and UV/EB?

UV Curing A True “Pollution Prevention”

Technology - No/low VOCs, HAPs, CO2

Not an end-of-pipe control technology

Energy is not used to process and/or transport and/or eliminate and/or destroy harmful emissions

UV/EB Reduced Transport Carbon Emissions

Truck Fuel Mileage: 5.7 mpg CO2 Emissions /gallon: 22.4 Pounds Average length of haul: 500 miles Fuel gallons/haul: 89.9 Emissions per haul: 2,014 lb CO2

Why Not UV In Mainstream Applications?

Issues to address 1 Major coatings companies not vested in UV Curing 2 Coatings chemists trained in conventional curing do not understand UV technology - Difficulty transitioning to UV - Liquid plastic – not a polymer - Solvents are reactive components

Why Not UV In Mainstream Applications?

3. Challenging problems - Light in versus light out for curing versus Durability - Pigmentation considerations - Handling of “non-drying” paint - Shadow cure

Opportunity in Lower Cost, Environmental Compliance

- Speed of cure translates into lower cost - Crosslinked coatings lead to high performance properties - Enabling technology - Environmental compliance – Priceless
