Applying PVC glue or adhesives on vertical materials can sometimes be a challenge due to gravity, PVC adhesives tend to flow out. This not only stains the base material but also leads to waste of the glue, Improving its thixotropic properties can effectively solve the problem:
- Take three equal portions of PVC glue
- one portion is left untreated
- while adding 0.5% and 1% of HIFULL® HL-200 respectively into the other two portions
- Disperse them for 20 minutes with a high-speed disperser at 1000rpm
- All PVC glues are thoroughly dispersed
To simulate the construction situation and observe the flow ability of the glue, we pour the three PVC glue samples out
when coming to a standstill, the PVC glue without fumed silica forms the largest disc shape. The one added 0.5% of HIFULL® HL-200 is smaller and the 1% one is the smallest.
Desired thixotropic properties of PVC glue can be achieved by controlling the added percentage of fumed silica. To accurately assess their thixotropic value, we use a Brookfield viscometer to measure the three samples.
Result shows that the PVC glue added 1% HIFULL® fumed silica has the largest thixotropic value. As the required thixotropic properties of PVC glue are related to practical usage, please check with our technical person to add a percentage of fumed silica based on your specific application needs.
