We are pleased to announce the introduction of a new solvent-based varnish
Hi-Therm BC-370. At a time when everyone is facing VOC issues with EPA, this product may offer some long term and short term solutions without moving to higher cost resin system.
In stricter states such as California and in areas of high population there are always pressures to lower VOC's. Typical VOC levels of solvent -based products are 4.5 pounds per gallon. We are finding current pressures at repair facilities to hit somewhere under 3.5 pounds per gallon. We have been able to accomplish this goal with BC-370. While meeting the VOC requirements, it also helps avoid the high expense of removal and disposal of solvent-based materials.
At the OEM level this can also be of significant help in states where facilities are permitted only so much emission on a total pound basis. Without a change in production, BC-370 offers an approximate 22% reduction in VOC emissions as compared to most typical dip and bake varnishes. This can also be a good answer to accounts that do not want to change from solvent-based technology, but have a need to increase production and ultimately VOC emissions.
Even if BC-370 is only an interim answer to an emissions issue, it can be a very valuable short-term step. This step can afford your customers enough time to fully analyze all the issues before changing to a longer term low VOC resin that may need to have VOC's under 1 pound per gallon.
On the performance side, this product will give you the same results as other typical Dolph baking varnishes. Average viscosity will be around 250cps. You will get film builds around 2mil per side and dry dielectric performance is 4000 volts/ mil to ASTM D115. Typical cure times are 1-2 hours at 325°F and 2-4 hours at 275°F.
