Product positioning
R-5670 is a second-generation two-component water-based polyurethane adhesive used with blue R-60C hardener. Under a defined 25 mm strip test, typical peel strength after one minute is approximately 25 N, supporting faster interior lamination cycles.
Website data are typical under defined TDS or project conditions and are not an unconditional production guarantee.

R-5670 FAQ
Direct answers for technical buyers, process engineers and sourcing teams.
01Why is R-60C hardener required?
R-60C forms the two-component crosslinked system that supports final strength and durability. The published ratio is R-5670:R-60C = 100:5-8 by mass; select the final ratio against the required peel strength, current TDS and line validation.
02What does approximately 25 N/25 mm after one minute mean?
It is a typical peel result for a 25 mm test strip under defined materials and process conditions. It demonstrates rapid initial strength but is not a guaranteed minimum for every substrate.
03Which interior materials can be bonded?
Project testing includes PVC, ABS, PP, 3D Mesh, flocked fabric, nonwoven material and PHC board. Surface condition and pretreatment remain important.
04Can R-5670 bond untreated PP directly?
Low-surface-energy PP varies by resin grade, recycled content, release agent and contamination. Actual production material must be screened with pretreatment, peel and aging tests.
05How does R-5670 support faster cycle time?
Faster initial-strength development can reduce waiting, holding or transfer time. Actual savings depend on coat weight, drying, activation, pressure, environment and substrate combination.
06How long can the mixed adhesive be used?
After R-5670 and R-60C are mixed, use the blend within 8 hours at room temperature, 23°C. Actual sprayability can still vary with temperature, batch size and equipment conditions.
07Which tests are needed before launch?
Validate initial and final peel, failure mode, heat resistance, humidity aging, thermal cycling, creep, open time and process stability on real parts under the customer standard.
