1215 Two-part Potting & Encapsulating Sealant is a low viscosity, two-part silicone encapsulant. It has good flowability, does not produce small molecules during curing, and has excellent thermal and insulating properties, no corrosion to various substrates, and meets the requirements of the EU ROHS. Suitable for potting and encapsulating power supplies, sensors, electronic components, circuit boards and solar photovoltaic junction boxes, etc.
FEATURES & BENEFITS: • Good flowability, low viscosity • Room temperature or heat accelerated cure • Good thermal conductivity • Good insulation and flame resistance • Good waterproof, moisture and weathering resistance • Passed UL certification
APPLICATIONS: 1215 Two-part Potting & Encapsulating Sealant is suitable for general potting and encapsulating for power supplies, inverters, ballasts, connectors, sensors, LED lighting components, solar photovoltaic junction boxes.
QUALITY ASSURANCE: 1215 Two-part Potting & Encapsulating Sealan has passed ISO9001/ISO14001 management system certification and passed QC080000 hazardous substance process management system certification, and strictly in accordance with ISO9001 quality system requirements for production and control of product quality.
MIXING RATIO: The ratio of Part A to Part B is 1:1 (volume ratio)
PACKAGING INFORMATION: Part A and Part B are separately packaged Part A: 25 kg plastic drum packaging Part B: 25 kg plastic drum packaging
COLOUR: Part A: white or dark gray fluid Part B: white fluid
USABLE LIFE AND STORAGE: The product should be stored in a cool, dry place at or below 27 °C. It has a usable life of 9 months from the date of production.
COMPATIBILITY: Certain materials, chemicals, curing agents and plasticizers can inhibit the cure of addition cure gels. Most notable of these include: organotin and other organometallic compounds, silicone rubber containing organotin catalyst, sulfur, polysulfides, polysulfones or other sulfur containing materials, unsaturated hydrocarbon plasticizers, and some solder flux residues. If a substrate or material is questionable with respect to potentially causing inhibition of cure, it is recommended that a small scale compatibility test be run to ascertain suitability in a given application. The presence of liquid or uncured product at the interface between the questionable substrate and the cured gel indicates incompatibility and inhibition of cure.
HOW TO USE: • Preparation Part A and Part B inevitably precipitate during transportation and storage. In order to ensure the use effect, Part A and Part B need to be thoroughly stirred in the respective containers before mixing, and the mixture is kept as stable as possible. Prevent excessive air ingress.
• Mixing and De-Airing These products are supplied in a 1 to 1 mix ratio, which is very robust in manufacturing environments and allows for some process and dispense equipment variation. In most cases de-airing is not required.
• Curing The curing reaction begins at the beginning of the mixing process. At room temperature, Part A and Part B are uniformly mixed to have a certain operable time, during which the viscosity of the mixture gradually increases, followed by gel and finally into an elastomer. The operable time is sensitive to the ambient temperature. The amount of encapsulant and the time of potting should be controlled according to actual needs to avoid waste.
• Repairability When it is necessary to rework defective parts, 1215 Two-part Potting & Encapsulating Sealant can be selectively and selectively removed. After the repair is completed, the part to be repaired can be refilled.
PRECAUTIONS: • Before using, please read the safety data sheet of this product for the safe use of the product. • Avoid contact with eyes before curing. If contact with eyes, rinse with plenty of water and consult a doctor. • Pay attention to ventilation in the construction and curing areas • Uncured products should avoid contact with children
