{"product_id":"fast-drying-copper-paste","title":"Fast-drying copper paste","description":"\u003cp\u003eProduct Name Fast-drying copper paste Product Overview Room-temperature fast-drying copper paste is a liquid conductive functional material prepared with high-purity spherical\/flaky copper powder as conductive filler, environmentally friendly room-temperature curing resin and special additives. It is a self-drying conductive material without high-temperature baking or UV curing assistance. With an exclusive formula suitable for manual coating and dilution spraying, it is not applicable to screen printing processes. The paste can form films and conduct electricity rapidly at room temperature, featuring excellent adhesion, stable conductivity and good oxidation resistance after film formation.

It achieves surface drying and stable conductive pathways within 10 minutes at room temperature, greatly shortening the preparation cycle and meeting the needs of high-temperature intolerant substrates and rapid experiments. • Precise and controllable process adaptability: The original paste is suitable for manual blade coating, dot coating and brush coating. It can be used for spraying after being diluted with special thinner to form uniform and flat coatings. Incompatible with screen printing, effectively avoiding screen clogging, printing leakage and uneven film formation. • Stable and reliable conductive performance: High-filling high-purity copper conductive system ensures uniform resistance and continuous conductivity after film formation. Equipped with special passivation additives, it inhibits copper layer oxidation and maintains low conductive attenuation during long-term use. • Wide substrate compatibility: Applicable to high-temperature intolerant and easily deformed substrates such as plastics, glass, ceramics, paper substrates, flexible films and conventional circuit boards, without high-temperature thermal damage, deformation or yellowing. Simple operation and high cost performance: No professional curing equipment or complex processes are required. It can be constructed manually at room temperature with high fault tolerance and low loss, suitable for small-batch laboratory R\u0026amp;D and simple industrial conductive coating repair. Application Fields • Electronic circuit repair: Broken circuit repair of PCB boards, local restoration of conductive circuits, conductive reinforcement of component pins, and renovation of old circuits. • Laboratory scientific research preparation: Conductive coating for electrochemical experimental substrates, conductive layers of flexible electrodes, conductive modification of various high-temperature intolerant substrates, and rapid conductive treatment of experimental samples. • Anti-static and electromagnetic protection: Anti-static coatings for plastic shells, insulating plates and instrument casings, and auxiliary conductive coatings for electromagnetic shielding of simple equipment. • Mold and light industrial devices: Conductive reinforcement of molds, conductive modification of small insulating devices, conductive coatings of crafts, and preparation of non-standard simple conductive structures. • Rapid prototype development: Temporary conductive circuits for scientific research prototypes, rapid prototyping of experimental devices, and trial production of small-batch non-standard conductive parts. Related Information • Storage environment: Store in a sealed, cool, dry, ventilated and dark indoor environment with temperature of 5–30°C and relative humidity ≤60%. Avoid direct sunlight, high-temperature baking and humid water accumulation to prevent accelerated drying and failure of the paste. • Isolated storage: Keep away from strong oxidants, acid-base corrosive substances and flammable and explosive organic solvents. Store separately and do not mix with screen-printable silver paste and carbon paste to avoid cross-contamination causing abnormal film formation and conductivity. • Application specification: This product is only suitable for coating and dilution spraying, strictly prohibited for screen printing, pad printing and other printing processes. Stir well before use after opening, and only dilute with special supporting thinner, do not mix with random solvents. • Sealing requirements: Tighten the cap and seal completely immediately after each use to prevent surface drying, crusting, stratification and precipitation caused by air exposure. Slight precipitation after long-term static placement is normal, and the paste can be used normally after uniform stirring.• Shelf life specification: The shelf life is 12 months under original sealed and dark room-temperature storage. It is recommended to use up within 1 month after opening to ensure optimal conductivity and film-forming performance. • Operation safety instructions: Keep the operating environment ventilated and away from open flames and high-temperature heat sources. Wear gloves and masks during construction to avoid long-term skin contact and inhalation of dust and solvents. Please e-mail for the detailed characterization data.
