Anti-tack or anti-stick coatings are designed to reduce the adhesive condition (stickiness) of a given material. The rubber, hose, and wire and cable industries are the largest consumers of anti-tack products but virtually every industry uses some form of anti-sticking agent. Anti-sticking agents differ from lubricants in that they are designed to reduce the inherently adhesive qualities of a given compound while lubricants are designed to reduce friction between any two surfaces.
Success or failure of an anti-tack solution depends on its ability to “wet” the tacky surface on which the coating is applied. Wetting refers to a liquid’s ability to spread out and adhere to a given substrate. Adherence to the surface ensures the coating will be durable, long-lasting, and effective. McGee Industries has perfected wetting technology over the last fifty years and currently offers tailor-made anti-sticking solutions and liquid emulsions that are easily diluted and fairly priced.
Finding an anti-tack agent that will reliably wet your materials is crucial to product quality, cost savings, and running an optimized production facility. When selecting your anti-tack agent, generalized coatings should be avoided at all cost. McLube offers tailormade products designed for specific materials and processes. We recommend an anti-tack agent after careful consideration of the following:
Facility goals related to cleanliness, environmental impact, and employee health
Process requirements, including but not limited to foaming, sedimentation and machine circulation rates, application methods, and tooling lifespan.
Material compatibility with anti-tack ingredients
Visual/non-visual considerations: does it matter if the coating changes the look of the material?
Process aids like anti-sticking agents are often considered less impactful than compounding ingredients because they do not (and should not) chemically alter the process material. Too many manufacturers overlook the importance of selecting an appropriate process aid with varying consequences, including:
Production cost increases due to fouling, downtime, and extra cleaning steps
Poor quality products due to material contamination
Environmental hazards and decreases in plant safety
Most anti-tack coatings will fail under factory conditions unless they are properly selected and tested outside the lab. We provide free samples and on-site trial assistance to all customers, large or small. Contact McLube for assistance with anti-tack applications and specific product information.
McLube Technical Representatives have the industry-related knowledge and experience required to analyze your process and recommend an anti-tack coating that will optimize your operation and improve finished quality.
