Bostik LADH1531AC is a neoprene solution contact adhesive designed for spray application onto a variety of substrates. It is suited for high-speed application where large, uniform, coverage is needed for quick bonding. Once applied, the laminate can be processed quickly, eliminating excess processing time for bond strength development.
FEATURES
- High water, oil, and heat resistance
- Sprayable
- Excellent green strength
APPLICATIONS
- Adhesive should be gently agitated prior to use. Gentle agitation consists of mixing the adhesive with a speed that allows a small vortex to be produced around the prop shaft that does not pull air into the adhesive
LADH1531AC is flammable. Take appropriate precautions when handling open containers. Containers should be grounded, equipment should be explosion proof and proper ventilation should be used.
- Substrates to be bonded should be clean and free from moisture, dirt, oil and other Exposure to oils and plasticizers at the bondline can cause degradation of the bond over time.
- The adhesive should be applied by conventional spray An orifice of at least 1.4 mm should be used for the fluid tip / needle. The air cap should have a minimum number of holes, to prevent clogging and make easier clean-up.
- For contact bonds, coat weight should be 2-5 g/ft² dry weight. This adhesive coat weight should be applied to both substrates
- Allow the material to dry properly prior to bonding. Forced drying with circulating air oven is recommended to eliminate the variability seen with drying at plant ambient Recommended drying is 80°C for 1 – 3 minutes. The optimum condition varies depending on oven choice, the amount of air flow over the part, and the amount of air exchange within the unit itself. The adhesive is flammable. Take appropriate cautions to handle material to prevent fires and explosions; use proper ventilation and grounding techniques with both liquid and vapors.
- Bonds can be made once the adhesive is Open time (from the point that the adhesive is dry until it is bonded) should be minimized for optimum bonding. Prolonged open time will allow the adhesive to collect contaminants from the environment.
- Position pieces Strong bond is made upon contact, limiting repositioning of the part. Use slip- sheets if necessary to assure proper alignment occurs.
- For contact bonds, press parts together for 10-15 seconds at 7 psi (0.5 kg/cm²). Press and dwell time are critical to contact bonding. Individual users should determine conditions appropriate to their specific Adhesive should have adequate green strength for handling immediately.
- Clean up of material can be done with Ethyl acetate, MEK, or Methylcyclohexane when the material is wet. If the adhesive is dried, MEK or Methylcyclohexane are better choices for cleaning.
