If you are comparing a product labeled “502 glue” with another labeled “super glue,” begin with the documents for the two actual products. The names on a quotation do not give you enough information to decide whether the products are equivalent for your application.
Identify the exact products
Ask for the manufacturer, product code, technical data sheet and safety data sheet for each offer. Confirm the adhesive chemistry from those documents. Our cyanoacrylate adhesive guide provides a starting point for enquiries about CA products.
Do not replace a product in an established range simply because a supplier considers the name familiar. The comparison should refer to an identifiable grade and sample.
Compare the specifications that affect your task
- Intended materials and application guidance.
- Viscosity and dispensing behavior.
- Fixture and full-cure information for stated conditions.
- Appearance and any relevant service limitations.
- Storage conditions and unopened shelf life.
Ask the supplier to explain any missing information. If a figure is provided without a test method or condition, clarify how it should be used in your evaluation. A faster-looking demonstration does not by itself establish better suitability for the finished joint.
Compare the complete pack
Check net content, container, nozzle, cap and the retail presentation. Similar-looking bottles may carry different fills or instructions. Align the quantity and packaging specification before comparing wholesale prices.
Zhouyi’s 3g, 20g and 50g enquiry pages describe pack options. If your purchasing brief specifically requires a 502-labeled product, ask our team to confirm current availability and the exact grade before ordering.
Evaluate representative samples
Test both proposed products on the same intended materials and follow each product’s instructions. Record the preparation, application and assessment timing. Agree the acceptance criteria before making a substitution in a retail or production program.
Make the quotation precise
Send your current product reference, application, pack size and quantity to Yiwu Zhouyi New Materials Co., Ltd. For branded packaging, review our OEM and private label service. The aim is a documented product match, with any differences understood before purchase.
