Basic Definition
Raw Tire Outside Release paint: Spray liquid on outside soft raw tires, keep rubber away from metal molds during tire baking.
Tire Mold Release Agent: Good & Bad Sides
✅ Good Points (Great for Big Tire Orders)
Save spray & worker cost: One spray works for 5-20 baked tire runs. No need to spray every raw tire, cut chemical cost and working time.
Tires look nice: It makes a thin even coat on molds, no liquid drops or thick buildup. Finished tires have clear words, clean tire patterns, no white fog or oil marks. Easy to stick labels or paint tires later.
Molds stay clean longer: The coat keeps hot rubber off molds. Less dirty buildup on molds, you do not need to clean or polish molds often.
Less bubble tires: Works well for snow tires and deep groove tires. Air comes out easily while baking, reduce broken bubble tires.
Easy work flow: No extra spray machine or drying machine needed. Workers spray directly on baking machines, save tire moving time.
❌ Disadvantages
Old rough molds or super sticky rubber may stick a little after long time working.
Workers need to keep molds hot enough when spraying for the first time.
Raw Tire Outside Release Paint: Good & Bad Sides
✅ Good Points (Great for Small Factories & Special Tires)
No tire sticking at all: Spray sticks tight on raw tires. Perfect for super sticky rubber, old broken molds, no stuck tires at all.
Super easy to use: No need to adjust mold heat. Just spray on soft raw tires, new workers can operate it fast.
Fit all tire orders: Good for small orders, test tire making, old retread tires and special shape tires. Works with all tire baking machines.
Use right after spraying: Put sprayed raw tires into molds directly, no waiting time to dry.
❌ Disadvantages
Cost more money: Must spray every single raw tire. Use more spray liquid, need extra workers for spraying work.
Makes tires look bad easily: Uneven spray or liquid drops leave white fog, dark spots and blurry tire logos, lower tire selling value.
Molds get dirty very fast: This spray moves to mold inner walls quickly, builds thick dirt. Factories need to stop production and clean molds very often.
Cannot stock sprayed tires long: Spray coat will fade or rub off during storage, tires will stick to molds when baking later.
