In tire manufacturing, low defect rates are an important factor in improving productivity. Defect rates tend to be high when tire producers use low performing release agents in tire curing. This occurs as these products are not protecting the bladder surface good enough. A performing release agent must insure the creation of a continuous protective release film on the bladder. This film represents a durable barrier between the bladder and the uncured tire. So, any sticking of the uncured rubber to the bladder surface is avoided. Further the durable film must insure a high slip level during the numerous release cycles. This is to insure perfect centering of the bladder inside the tire to promote optimum tire balance. An excellent slip performance also allows to avoid pinched and folded bladder defects. Furthermore, the performing release agent has to allow for lowest dirt build up on molds and spray equipment and should ease optical inspection of the final, cured tires in quality control.
All these advantages will as a whole allow to strongly reduce scrap and press down time in tire production thereby improving the operational results of the tire factory.
To find the best answers to these requirements our experts at ELKEM Silicones developed the durable and fully transparent LYNDCOAT® BR2205 and BR2105 multi release formulations.
They have been designed to allow for reduced usage volumes resulting in a thinner film, while still providing a durable and slip promoting release performance.
Due to the highly friction resistant components of the formulations, the thin, transparent film sticks to the bladder surface where it provides durable protection from chemical and mechanical aggression.
The highly slip providing ingredients will insure a long-lasting slip effect allowing for multiple release cycles for a single product application.
LYNDCOAT® BR2205 & BR2105 durable multi release agents ensure clean operations, which is critical for tire manufacturers seeking to reduce defect rates and optimize processes. They feature:
- No paint spills when applied
- Fast drying to a clean and transparent film
- Elimination of flake-off and mold pollution
- No stain on the tire
- Bladder protection
- Numerous release operations per application
- High and long-lasting slip level
LYNDCOAT® BR2205 & BR2105 work by forming a thin, protective release layer on the bladder surface. They so enable optimal operations with an increased bladder life cycle.
These durable multi release can be applied to the tire inner liner and will then transfer to the bladder surface during tire curing.
Alternatively, they can be applied directly to the bladder surface. Valid application methods :
- Air Spray
- Air Assisted Spray
- Air less Spray
- Spinning disk
- Spinning cone or bell
For an application with a brush we recommend to choose Lyndcoat® BR2205.
LYNDCOAT® BR2205 & BR2105 achieve high performance levels with reduced coat weight, helping manufacturers to generate significant cost savings.
Furthermore, manufacturers can count on the fully integrated supply chain of Bluestar Silicones and our worldwide production footprint. This means security of supply, on time delivery and availability of local technical support for our LYNDCOAT® range of cutting-edge release agents.
Compared to other commonly used products in the market, LYNDCOAT® BR2205 and BR2105 offer vast operational and cost-effective benefits for tire release, including:
- Improved quality results in tire manufacturing
