Slab dip coatings applied to uncured rubber compounds to prevent them from sticking to themselves, other stock, or processing equipment during storage and handling.
Overview
Anti-tack agents are coatings applied to uncured rubber compounds to keep slabs, strips, and extrudates from sticking to themselves, each other, or processing equipment during storage and handling. Without one, tacky stock blocks together into an unusable mass, builds up on rollers and festoon equipment, and shows up downstream as blisters and dusting. A properly matched anti-tack does more than stop sticking; it’s built for a specific compound and cure system (sulfur, peroxide, resin, or metal oxide), stays uniformly dispersed without settling or foaming, dries quickly, and leaves no residue that interferes with rubber-to-rubber or rubber-to-metal bonding. Getting the anti-tack right, and running it at the correct solids level on properly maintained equipment, has a direct impact on production efficiency, product quality, and cost, making it one of the smaller but more consequential decisions on a rubber processing line.
Why PolyDip
Most anti-tack problems trace back to one issue: a generic product being asked to do a job it wasn’t designed for. PolyDip takes a different approach; a targeted anti-tack matched to your specific compound, cure system, and downstream finishing requirements, engineered to form a uniform, stable dispersion that won’t settle, foam, or dust.
A 2-Step Approach
Anti-tack performance isn’t only about the chemistry in the drum; it’s about how that chemistry interacts with your equipment and process conditions.
That’s why ARP Materials takes a two-part approach:
- The right product for your line. We match PolyDip formulations to the compounds you’re processing and the downstream finishing steps that follow; not a one-size-fits-all dip.
- Equipment optimization. We work directly with your team on the production floor, checking agitator function and placement, air knife positioning, festoon fan operation, and tank mixing, to make sure the equipment applying the anti-tack is set up to succeed.
For higher-volume operations, ask about the Automated Dilution System, offered at no cost, which maintains proper active solids levels directly in the process tank, bringing consistency to your dip without tying up plant personnel.
PRODUCT BENEFITS
- Lower depletion rate — PolyDip’s uniform dispersion resists settling, so more of every liter actually treats your compound instead of ending up as sludge at the bottom of your process tank
- Clean-running equipment — minimal foam and buildup on agitators, belts, bars, and chains means less downtime for cleaning
- Fewer blisters and wet-stock complaints — properly formulated dispersions dry faster and more uniformly through the festoon
- Compatibility across cure systems — sulfur, peroxide, resin, metal oxide, and sulfur-donor systems are all covered across the PolyDip line
