MOSCOW (MRC) -- Dow introduces first solventless silicone conformal coating with UV and moisture dual cure for high-volume electronics manufacturing, said the company.
Dow introduced today at IPC APEX EXPO 2020 new DOWSIL™ CC-8030 UV and Moisture Dual Cure Conformal Coating, the industry’s first solventless silicone conformal coating with an ultraviolet (UV) and moisture dual cure system for high throughputs. This new environmentally responsible silicone technology promotes sustainability, health and safety while reducing processing costs through automated spraying and fast, energy-efficient UV curing. Other silicones support UV curing, but none are conformal coatings with a low enough viscosity for spray coating and with a secondary moisture cure for shadowed areas. The new DOWSIL™ product also offers more reliable protection against stress and thermal cycling versus competitive materials.
Brian J. Chislea, senior electronics application engineer at Dow, will discuss the new DOWSIL™ CC-8030 UV and Moisture Dual Cure Conformal Coating during two poster sessions at IPC APEX EXPO. The first session is scheduled for today, Tuesday, Feb. 4, from 10:00 to 10:30 a.m. Pacific Standard Time (PST). The second is scheduled for Wednesday, Feb. 5, from 4:30 to 5:00 p.m. PST.
"Dow has long been an innovative leader and developer of leading-edge conformal coating technologies that address our customers’ most pressing needs,” said Chislea. “DOWSIL™ CC-8030 Coating is an excellent example of this. “By listening closely to our customers, we responded with this first-of-its-kind material that can help electronics manufacturers meet their sustainability and productivity goals, and more."
DOWSIL™ CC-8030 UV and Moisture Dual Cure Conformal Coating is an environmentally progressive solution for protecting rigid printed circuit boards (PCBs), sensitive electronic components and fine-pitch designs from environments with airborne contaminants. This high-performance silicone conformal coating is formulated without benzene, toluene, ethylbenzene or xylene (BTEX) solvents. The new DOWSIL™ Conformal Coating also has a low modulus for delicate components and high elongation for reliable protection against stress. To provide an even greater level of PCB protection, DOWSIL™ CC-8030 UV and Moisture Dual Cure Conformal Coating can be applied in multiple layers. Compared to leading acrylated urethane UV cure coatings, the new silicone-based Dow technology provides superior protection against thermal cycling.
As MRC informed earlier, Dow Chemical, the world's petrochemical major, has put order controls in place for vinyl acetate monomer (VAM). The letter dated January 8 said, effective immediately, volumes will be based on previous monthly averages of purchased volumes, or limited to monthly maximum volumes specified in contracts. The letter does not provide details about how long the order control will be in place.
VAM is the main feedstock for the production of ethylene-vinyl-acetate (EVA).
According to MRC's DataScope report, November EVA imports to Russia dropped by 8,9% year on year to 3,440 tonnes from 3,780 tonnes in November 2018, and overall imports of this grade of ethylene copolymer into the Russian Federation decreased in January-November 2019 by 18,9% year on year to 35,95 tonnes (44,330 tonnes in the first eleven months of 2018).
The Dow Chemical Company is an American multinational chemical corporation headquartered in Midland, Michigan, United States. Dow is a large producer of plastics, including polystyrene (PS), polyurethane, polyethylene, polypropylene, and synthetic rubber.
