Technology
Why replace powder coatings?
Powder coatings cause endless housekeeping concerns and foul machinery as they migrate around the plant. Users of our powder-free coatings report overall efficiency gains because they spend much less time cleaning plant floors and equipment. McLube’s liquid anti-tack coatings are also much more effective anti-stick coatings than traditional powders. Our liquid coatings form a clear, non-staining film on the rubber surface that provides more uniform anti-stick characteristics with help from our proprietary surfactant technology.
Common powder coatings like mica and talc are also a safety concern for employees due to the health risks related to prolonged inhalation of these substances. McLube’s water-based coatings deliver unparalleled anti-stick properties directly to the rubber without dispersing into the air or ventilation system and do not contain mica, talc, or heavy metals. Our liquid coatings also settle out from dip tanks much slower than stearates and slurry fillers because our active ingredients are easily emulsified into a liquid base. Slower settling means our products eliminate the need for some of the extra agitation equipment required to keep powder-based coatings like stearates and slurries dispersed. Contact McLube® for more information and assistance with replacing powdered coatings in your facility.
Performance
Curing and Molding
Uncured rubber is inherently soft and tacky. While these attributes are a nuisance to the rubber industry, the chemical structures that cause “stickiness” make curing steps like vulcanization possible. McLube® anti-tack coatings will prevent uncured rubber slabs from adhering to one another without chemically altering the uncured rubber or interfering with finishing steps. There is no need to remove our anti-tack coatings before curing or molding elastomers. Our coatings will harmlessly melt or compound into rubbers during molding at higher temperatures and may also facilitate release for some applications without affecting the physical or chemical properties of the elastomer.
