RTV terminology can hide an important purchasing distinction: a silicone base for formulation is not necessarily a complete material ready to cure in the customer's assembly. Resolve that distinction before comparing quotations or planning a production trial.
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
- Ask the supplier to identify the exact supplied form and which additional components, if any, are required. Request current documents rather than relying on a short catalogue label.
- Assign responsibility for formulation, process development and cured-product testing. Make sure the purchase specification describes the supplied material rather than an unverified finished-system property.
- Obtain a representative sample and evaluate it only within the agreed formulation and handling procedure. Keep the resulting test records tied to all component identities.
How to use the results
A lower raw-material price is not a like-for-like alternative to a complete qualified sealant. Compare the full technical scope and the work still required. Do not release a base material directly into production under instructions written for another product.
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
Does the name room-temperature-vulcanized rubber mean no other components are needed?
No. The JY-107 description refers to use with a crosslinking agent and catalyst. Confirm the exact supplied grade and approved system with the supplier before use.
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.
