Application guidance, handling & ordering details
Product Series / Model: SQ-61 / SQ-62 / SQ-63 / SQ-65 / SQ-66 / SQ-67 / SQ-68
Select polyurethane adhesive for shoes around both materials in the joint and the footwear assembly process. Our solvent-based PU range includes separate SQ grades; the catalogue identifies specific material uses for SQ-69 and RN addition for selected grades. Tell us whether you need an initial bonding trial, technical documents or a production quotation so the team can review the appropriate product route.
Product options and suitable applications
| Series / category | Product type | Selection note |
|---|---|---|
| SQ-61 / SQ-62 | General PU adhesive grades | Source explicitly identifies RN addition for these rows. |
| SQ-65 / SQ-66 | PU adhesive grades | Confirm the current product document and process. |
| SQ-63 / SQ-67 / SQ-68 family | PU adhesive grades | Source describes hydrolysis-related performance qualitatively. |
| SQ-69 | PU adhesive | Source lists PVC, TPR and nylon bonding contexts. |
What matters in a trial
- Supply both materials and their surface preparation. The adhesive and treatment agent should be evaluated as part of the same bond.
- Do not generalize an RN addition instruction to every product in the table. Some rows specify it; others do not.
- Where the catalogue uses qualitative performance language, ask for the relevant test conditions. This website does not convert those descriptions into numeric guarantees.
Technical data and documents
Request the current TDS and SDS for the exact model. Published catalogue properties depend on the product category and evaluation conditions; where the source does not establish a unit or complete test method, contact our technical team.
| Information | How to obtain it |
|---|---|
| Viscosity, application settings and conditioning | Contact our technical team for the exact grade. |
| Pretreatment and compatible products | Confirm against your actual substrate and process. |
| Testing information | Provide the required test method and acceptance criteria. |
Prepare your sample request
Include the substrate name and finish, printing or assembly process, current product and the problem you need to solve. A material offcut and a photograph of the finished construction help us distinguish appearance requirements from interface or flex failures.
Frequently asked questions
Is RN required for every SQ adhesive?
The source identifies it for specific grades. Request the exact current mixing instruction for the selected model.
What should a bonding sample request include?
Both substrates, any existing primer, assembly steps, current failure and target test.

Evaluate it on your own material
Send the material type, surface finish, current process and required test. Our technical team can help identify a trial candidate and the appropriate TDS / SDS.
Selecting PU adhesive for footwear manufacturing
Use this page to review solvent-based polyurethane adhesive options for a footwear production joint. Material names alone do not select the grade: describe both bonding surfaces, their finishes and the assembly steps.
When a joint separates, photograph both exposed faces and state whether the issue appears during assembly, after conditioning or in the required test. Keep the current adhesive and preparation records with your sample. A photo alone does not establish bond strength or the cause of failure.
Request technical data, trial guidance or a quotation
Send the material pair, current adhesive or selected model, production process, target test and estimated quantity. For distribution, also describe your factory customers’ applications. Our team in China will confirm the suitable product documents and trial arrangements.
Request the current TDS and SDS for the exact grade and any compatible components. Adhesive sample availability, packaging, minimum order quantity, production lead time, freight and payment terms are confirmed separately; ink purchasing conditions should not be assumed for adhesives. Prices are provided by quotation rather than published as a fixed price list.
