What are the fundamentals behind controlling modern adhesives and sealants in the application process?
Saint Clair Systems has dedicated 25+ years to the science of temperature and viscosity control. We’ve used our expertise to provide adhesive and sealer process solutions to manufacturers in a number of different industries and applications:

With over 3600 applications under our belt, we have the experience and expertise to streamline your processes and cut costs.
Tesla is in Fremont, CA, where temperatures can drop below 10°C and rise above 40°C. This created a problem with two of their sealant lines. Inconsistencies in dispense temperature created quality issues and a waste of material. Beads were too small when it was cold, and they were using 50% more material when it was too hot. Here's how we helped.

We reported increased stability in striation patterns when applying PVC to aluminum to create a woodgrain finish. We reported significant reductions in color match issues as a result of consistent film build
Steelscape reported reduced “ropiness” when applying Polyester to steel resulting in a finish that “looks sprayed rather than rolled, Steelscape reported 75% reduction in solvent pop due to reduced solvent addition. Steelscape reported 100% reduction in solvents added to primers and backers and 60% reduction in solvents added to finish coats. This was the easiest capital project implementations that we’ve ever done!
Our system provided the biggest bang for the buck of any capital project so far!
Reported solvent reductions between 80% - 100%
As part of our ongoing continuous improvement plan at Roush, we decided to take a more aggressive approach to our temperature control in the paint shop. The resulting quality improvement was immediately noted and helped drive our FTC (First Time Capability) up and sustain it where we needed it to be.
At Valspar, we formulate our paints to run under a variety of different conditions and process variables. One of the primary variables is the paint temperature, which can vary from 40°F to 100°F based on the conditions at the coil coating facility. This wide swing in temperature can play havoc with both paint viscosity and application setup. Having consistent and targeted paint temperature removes this process variable and its effects from the equation. Additionally, having consistent paint temperature ensures optimal (minimal) usage of expensive reducing solvents to attain the desired viscosity and applied paint film thickness.
“Being able to control the temperature within a narrow range as paint is being used can be very beneficial. The most obvious benefit is a reduced amount of solvent usage. This is not only more economical for the coater but also reduces the environmental impact and health risks to their employees. Reducing the amount of solvent added [provides] additional benefit to the performance of the paint being used. The two major benefits are: Reduced possibility of having solvent popping or blistering problems. The addition of too much solvent to certain paints or certain colors of paints may cause color shifts or gloss changes and by reducing the amount that needs to be added this can be avoided.”
