UV Curable Coatings
UV CURABLE COATINGS
ADVANTAGES
1. Much faster than thermal processes - UV Coatings cure in a matter of seconds, rather than minutes or hours.
2. Faster start-ups and shut-downs and lower energy consumption - UV Lamps turn on and off almost instantaneously. There is virtually no energy or time lost waiting for the oven to come up to temperature in order to start or resume production, and stand-by modes are not necessary.
3. Improved productivity - Because UV coatings cure in a matter of seconds, higher line speeds are possible.
4. Less contamination - Lower reject rates - No air movement to exhaust byproducts of combustion is necessary in UV curing systems. This reduces the chance of air-borne contamination of the coating.
5. Reduces or eliminates VOC emissions and solid waste disposal - Many UV coatings are 100% solids and contain no solvents: thus VOC emissions can be eliminated.
6. Less space required - Due to the speed of cure, UV systems require less floor space.
7. Superior finishes - UV curable coatings can offer improved performance and visual properties.
8. Less thermal, noise, and air pollution - Less thermal pollution of the workplace and less noise pollution from fans, burner regulators, etc. due to low heat requirement.
9. Can be used on temperature-sensitive substrates - Substrates such as wood and plastic, and fully assembled products that may contain gaskets and/or fluids, can be safely coated with UV curable coatings.
UV Coating on Head Lamps
Plastic to be use : PC, BMC, PBT & ABS
*PC – Polycarbonate
*BMC – Bulk Molding compound (Thermoset plastic)
*PBT - Polybutylene terephthalate (Thermoset plastic)
*ABS - Acrylonitrile Butadiene Styrene
> In Two wheeler vehicles headlight made with PC plastics.
> Four wheeler and heavy vehicles headlight made with temperature resist plastic like BMC & PBT and ABS in rear cases.
The earliest headlamps made with metal components but due to high cost and heavy weight it replace with diff. plastic and chrome plating replace with vacuum metalizing.
Advantage of UV vacuum metalizing :
> High reflectivity or Finish like mirror
> Cost effective
> Fast productivity
> Alkali, acid & salt resistance
UV Coatings for Hard Coat
Plastic to be use : PC
*PC – Polycarbonate
Advantages :
> Scratch resistance and long durability
> Better resistance from UV degradation over period of time
> Clear and better light transparency
Application by:
> Spray
> Flow or shower
> Dipping
Curing method :
> Radiation curing (UV Lamps)
> Thermal curing (Oven)
UV LED CURABLE COATING
GMM research and developed LED curable coating first in India.
At the same time, LED curing technology has become more efficient in delivering higher energy to the media, thus driving environmentally clean, energy efficient and compact size units with increased throughput and process flexibility.
We are the one who supplying successfully LED curable coatings on plastic substrate like on helmet to India’s biggest helmet brand owned by Vega
