Inside Tire Paint

McLube® offers mineral-filled inside tire paints for bladders that generally do not have integral grooves to facilitate air bleed. All of our filled inside tire paints are water-based and inherently VOC-free. We currently offer low-fill (LF), medium-fill (MF), and high-fill (HF) inside tire paints as well as custom fills to suit customer needs. McLube’s filled inside tire paints possess thixotropic properties that ensure the coating will not run off the applied surface for consistent, uniform release characteristics. McLube® offers single-release filled inside tire paints as well as more durable options that will provide multiple releases per application.

McLube® also offers water-based unfilled inside tire paints for bladders that have integral venting grooves to facilitate air bleed between the tire and bladder during the cure process. McLube’s line of unfilled inside tire paints includes silicone-free options, ready-to-use products, and concentrates intended for inhouse dilution with standard tap water. These products will provide the ideal degree of slip to aid release and create a more aesthetically pleasing inner tire when compared to filled inside tire paints. These products may be tailored to single-release applications or enhanced for improved durability and multiple releases per application.

Single-release inside tire paints are ideal for producing tires with deep contours that tend to trap more air. Single-release tire paints are typically non-reactive coatings, do not transfer to the bladder, and thus do not impart a releasing film on the bladder that will offer multiple releases per application. Some customers may be able to achieve several releases before application is necessary, but generally frequent application is required to maintain sufficient slip for these applications. Single-release inside tire paints are typically used to produce high-performance and low-profile specialty tires.

These semi-permanent inside tire paints are ideal for high-volume tire production where decreasing costs and improving process efficiency are crucial objectives. These coatings are designed to transfer to the bladder after the first tire is cured and removed. Active ingredients in these coatings will form a durable, bonded release film on the bladder that provide up to 15 releases per application depending on individual process conditions and tire type. McLube’s experienced Technical Representatives and Formulation Chemists will work with the customer to provide a multiple-release ITP that achieves all of your process efficiency goals.
