R-8 Hot Melt Butyl Sealant for Glass

2. R-8 has a lower water vapor transmittance and better aging resistance, which provide effective guarantee for producing high quality hollow glass.

3. R-8 has higher cohesive strength, especially suitable for large plate hollowglass production.

  Hot melt Butyl Sealant Directions for use:
1. Article interval or grease, dust and other dirt on the glass, can reduce the sealing and bonding effect of all sealant, must be removed before use.

2. R-8 can use hot melt butyl extruder and also automatic gluing machine coating. The Construction environment temperature requires not less than 10 ℃.

3. Extrusion temperature is 110 ~ 130 ℃, glue mouth temperature should be higher than the plastic cylinder temperature, about 1 ~ 2 ℃. Please note: specific temperature is closely related to the heating efficiency of machines and the factors such as the accuracy that the temperature measurement shows.   

4. The user can adjust the temperature and the glue pressure according to the making conditions and the requirements of make hollow glass, to achieve the best effect of coating. We do not recommend use the pressure glue pump, because its pressure is low and difficult to adjust, is not conducive to operation.
