Product Series / Model: SQ-61 / SQ-62 / SQ-63 / SQ-65 / SQ-66 / SQ-67 / SQ-68
The solvent-based PU adhesive table contains general and higher-performance grades. It also names material uses for SQ-69 and identifies RN addition for specific rows. These differences should be preserved when requesting a sample or comparing a trial.
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.
