HIGER BOND HB-1680 Flame-retardant electronic insulation yellow glue (component fixing glue / UL 94V-0)
Product Overview
HIGER BOND HB-1680 is a high-performance single-component self-extinguishing flame-retardant electronic yellow glue based on chloroprene rubber (Chloroprene Rubber). The appearance of this product is non-transparent yellow-white mucus with high consistency, specially developed to meet the high standards of flame retardant safety of equipment in the electronics, electrical appliances and motor industries.。
HB-1680 passed the U.S.UL 94V-0 flame retardant certification (File No. E117973), and fully complies with EU RoHS/WEEE environmental standards, and does not contain heavy metals such as lead and mercury and brominated flame retardants such as PBB and PBDE.. The product dries quickly and forms quickly (drying time to touch is about 3 minutes), combining excellent electrical insulation properties, anti-vibration buffering and mechanical shear strength, widely used in bonding and fixing components and anti-vibration and dust-proof insulation of various switching power supplies, adapters, monitors and home appliance motherboards。
Core advantages and features
Authoritative UL 94V-0 flame retardant certification:It has excellent self-extinguishing flame retardant properties and has passed UL Yellow Card certification (UL 94V-0, thickness 1.5mm / 2.0mm, File No. E117973), meeting the flame retardant safety and fire protection specifications of electronic and electrical equipment.。
Environmentally friendly halogen-free formula:It does not contain heavy metals, polybrominated biphenyl (PBB), polybrominated diphenyl ether (PBDE) and other harmful ingredients, and fully complies with the requirements of the EU RoHS / WEEE environmental protection directives。
Quick fingertip positioning:Drying time to the touch is only3 minutes, can effectively shorten the assembly line cycle and improve the efficiency of electronic assembly operations。
High solids and medium consistency:The solid content reaches52% ~ 54%, the consistency is30,000 ~ 45,000 cps, has good gap filling ability, good dispensing and molding properties, and is not prone to collapse。
Excellent electrical insulation:
Tested at 500V DC (after 250 hours at 25°C), the resistance and insulation are up to$4.1 \times 10^{13}\ \Omega\cdot\text{cm}$；
The dielectric breakdown strength reaches21 kV/mm(ASTM D149 standard)。
Strong shock-resistant adhesion:The shear strength can reach30 kg/cm², can firmly resist loosening damage to electronic components caused by mechanical vibration and drop impact.。

Typical application areas
Fixing large-size components on PCB board:Root dispensing fixation and anti-vibration buffering of heavy-duty components such as filter electrolytic capacitors, high-frequency transformers, and inductance coils in switching power supplies, inverters, and computer power supplies.。
Insulation and dustproof sealing of electronic and electrical components:Moisture-proof, dust-proof and insulating sealing around exposed terminals, electronic pins, sensor housings and connectors。
Prevent displacement of components during wave soldering:Before the wave soldering process, the plug-in components are pre-fixed by dispensing glue to prevent the components from tilting, moving or floating during the process transfer.
Multi-material universal structural bonding:Quickly fit and fix various metal, engineering plastics, rubber gaskets and other components in electronic and electrical structural parts.
Instructions for use and construction suggestions
Surface preparation:Make sure there is no dust, moisture, grease, dirt or any impurities attached to the surface. Glue before use pleaseBe sure to mix thoroughly。
Gluing operation:
Component positioning:It can be used with manual or pneumatic dispensing equipment to directly inject glue at the contact point between the component root and the circuit board.
Surface bonding:Use a brush or roller to apply a thin layer of glue to the surface of the material; If the surface is rough or uneven, please apply moderate pressure when painting to ensure that the glue completely fills and covers the gaps.。
Drying and fitting:After applying the glue, let it sit for a few minutes to wait for the surface to dry and harden., then put the two adhesive surfaces together and apply a certain amount of pressure to make them in close contact.。
Fully cured:Recommendations after bonding is completeLet sit for 24 hours, to achieve the best bonding quality and shear strength。
Safety and storage:
This product contains organic solvents. The construction site must have good ventilation and exhaust facilities to avoid prolonged inhalation of steam and contact with skin.。
Fireworks and sparks are strictly prohibited。
When not in use, please seal the lid tightly and store in a cool, dry and dark place.。
