Double Bond Chemical, a manufacturer of photoinitiators and oligomers recently increased its annual output in photoinitiator production, from 4,500 tons to 9,000 tons, and its annual output in oligomers production increased to 10,000 tons. DBC’s production line of UV curable oligomers in its Jiangsu factory in China has also expanded.

In traditional spray coating procedures, when the viscosity of paint and inks get high, additional processing before UV curing is a prerequisite, such as the adjunction of solvent. Products typically used to reduce the viscosity by increasing the dosage of monomers leads to monomer migration issues or the adjunction of solvent causing environmental issues.

DBC develops UV curable oligomers with higher molecular weight, low visicosity, such as products DM576, 1710, 1720, 1283C for use in coating mobile phones. These UV curable oligomer products featur low viscosity without monomer migration issue. Furthermore, DBC also improves the physical properties of its products, such as smell, skin irritation and cross linking issues, the company stated.

 Many of the physical property issues are terminated by DBC hydrogen bond technology in which obstruction within H-Bond is lowered and ideal viscosity is rendered. With advanced technology, the need for monomers is reduced to even none. The technology is expected to be applied in green standards of VOC, replacing traditional 3D spray coating materials in woodworking, furniture, bicycle and 3C sectors. DBC develops UV curable oligomers with 1,000 to 1,500 molecular weight and 1,000 to 3,000 viscosity CPS (under 25℃) that meet the need of its global customers.
