AI-Powered supplier vetting

SummaryThe supplier is a Shenzhen-based limited company focused on electronic and industrial adhesives, with stated R&D, standardized production, testing, and technical-service capabilities. It offers ODM and OEM services and supports prototyping, small-batch trials, and large-scale delivery. However, the supplier reports no available SDK, no new products in the past year, no overseas showroom, agents, branches, or offline trade-show participation, and only five employees. Quality assurance and related procedures are stated, but several procedures lack written records or completed assessment records. Financial-related entries identify years but provide no assessable financial results. Customer cases are not explicitly documented, although OEM service for well-known brands is claimed.

Supplier typeThe supplier is a limited company with five employees and no stated parent-group affiliation. Its business focuses on R&D, production, sales, and technical services for electronic and industrial adhesives, supported by a production base and laboratory in Shenzhen.

R&D capabilityThe supplier describes independent R&D, formula innovation, process improvement, application development, a professional R&D laboratory, and rapid prototyping support. However, it reports no available SDK and no new products during the past year, creating a documented limitation despite its broader R&D claims.

Production capacityThe supplier states that it operates standardized production lines and a modern production base with testing instruments and quality management systems. It also claims support for small-batch trial production and large-scale delivery, which is direct evidence of production capability.

Customization capabilityThe supplier explicitly provides ODM services and supports rapid prototyping, small-batch trial production, process optimization, and mass-production applications. These capabilities directly support customized adhesive development and production.

Product Q&A

Q:What is the mixing ratio of CY-8800 A/B?

The mixing ratio by weight is A (curing agent) : B (base resin) = 30 : 100. Strict weight proportion mixing is required with dedicated dispensing equipment, vacuum defoaming is recommended to eliminate bubbles.

Q:What curing options are available for this PU potting resin?

Two curing modes: 1. Room temperature curing at 25, fully cured in 24 hours, gel time 360 mins; 2. Heat accelerated curing: 60 for 60 mins or 80 for 30 mins for mass production efficiency.

Q:What are the core advantages of CY-8800 compared with common potting glue?

It is solvent-free eco formula with RoHS & halogen-free compliance; high thermal conductivity and super insulation over 24kv/mm breakdown voltage; ultra-low water absorption (0.5% for 30-day immersion); wide temperature resistance -40~120; elastic cured layer for shock absorption, perfect for outdoor & automotive electronics.

Q:What products can CY-8800 A/B be used for potting protection?

Main applications include LED driver power supplies, small transformers, power adapters, new energy storage control modules, automotive circuit boards, sensors, CCTV & communication outdoor power modules.

Q:How to store the raw materials and what is the shelf life? Any safety notes?

Sealed storage at 5~30 cool ventilated warehouse, shelf life 6 months. Keep away from direct sunlight, heat & open flame. Wear goggles, rubber gloves and organic vapor respirator during operation. In case of skin/eye contact, rinse with plenty of clean water immediately and seek medical help if discomfort persists.
