A broad catalogue viscosity range is not a specification for the lot you intend to buy. Connect the selected viscosity grade to the measurement method and the downstream formulation so quotations can be compared on a meaningful basis.
Evaluation scope
The JY-107 page describes a silicone material that cures with a crosslinking agent and catalyst. It should not automatically be treated as a ready-to-use cartridge sealant or as a complete electronics encapsulant. Establish the supplied grade and formulation responsibilities before evaluating a cured system based on this material.

Keep these variables in the record
| Item | What to record |
|---|---|
| Supply form | Confirm whether the material is a base or a complete system. |
| Formulation | Identify the approved components and their responsibilities. |
| Geometry | Define joint or specimen thickness and exposure. |
| Qualification | Evaluate the cured formulation, not only the base fluid. |
Trial and review plan
- State the target grade and intended formulation route. Ask the supplier to provide the relevant viscosity range, measurement temperature and method for that grade.
- Compare the sample and COA using compatible test conditions. Avoid treating values reported in different units or by different methods as automatically interchangeable.
- Evaluate processability in the approved formulation and retain reference material. Define when an incoming deviation requires review rather than changing the formulation to compensate.
How to use the results
Specify what you need to control, not the widest range found on a catalogue page. Viscosity supports material identification and handling decisions but cannot by itself predict the cured system's strength, adhesion or service performance.
Information to include in an RFQ
Explain whether you need a silicone base or a ready-formulated system. Provide the intended substrate and cured-property requirements, and request the current specification and safety documents. Cure chemistry, formulation compatibility and end-use qualification must be agreed with the supplier and your technical team.
Frequently asked questions
Can a viscosity value be compared without its test temperature?
It is an incomplete comparison. Request the temperature and method, and resolve unit or method differences before deciding that two supplied grades are equivalent.
Are these proposed checks certified results for this grade?
No. This article describes evaluation and procurement questions, not completed customer trials. Request current grade-specific documents and appropriate test evidence. The acceptance criteria must fit the actual formulation, process or assembly being qualified.
