Instructions for Use
Pre-processing – Clean and prepare the surface of the substrate to be bonded or coated, using a cleaning agent to remove rust, dust, oil, and other contaminants. It enables primerless adhesion to a wide range of materials, including glass, metals, and most commonly used industrial plastics.
Sizing – Cut the nozzle to the required size and load it into the caulking gun. Extrude the adhesive onto a thoroughly cleaned surface, ensuring even distribution. When bonding, simply bring the mating surfaces together and hold them in place. At room temperature and 55% relative humidity, the exposed adhesive will form a skin within approximately 15 minutes. Therefore, all processing steps must be completed before skinning occurs.
Curing – After the adhesive skin forms, curing continues from the surface inward; under ambient conditions—room temperature and 55% relative humidity—the adhesive will cure to a depth of approximately 2–3 mm within 24 hours. In very deep layers, particularly in areas where atmospheric moisture has limited access, full cure will require a longer time. At lower humidity levels, curing times are extended. When handling and packaging bonded components, users are advised to allow sufficient dwell time to ensure that the bond and seal remain unaffected. This duration depends on numerous factors and should be determined by the user for each specific application.
Note: After use, any unused adhesive should be tightly sealed and stored. When reusing, if a thin skin has formed at the seal, simply remove it; this will not affect normal use.
Usage Restrictions
Adhesion success rates are lower on low‑energy (surface) plastics such as polyethylene, polypropylene, and PTFE. Users should conduct preliminary tests for each specific application to achieve satisfactory results.
This product has not been tested or claimed to be suitable for medical or pharmaceutical use.
