Use Scenarios
STK improves uncured tack properties in tire manufacturing
Acetylene Tackifying Resin STK enhances unanalyzed surface adhesion in rubber formulation at the uncured stage, especially in tire manufacturing. Use of this resin enables layers of rubber to bond securely before vulcanization, supporting assembly integrity. In tire building operations, STK adds high unvulcanized adhesiveness that ensures components such as tread, carcass, and inner liner remain aligned during handling. This performance supports consistency in downstream vulcanization of rubber, ensuring that cured structure forms with minimal displacement or delamination before cure.
Conveyor belts and rubber dams benefit from STK’s uncured bonding performance
In conveyor belt and rubber dam production, Acetylene Tackifying Resin STK contributes high uncured stickiness that holds rubber layers firmly before vulcanization. This adhesion supports accurate placement of layers such as fabric plies or rubber sheets during assembly. When forming belts or dams, the use of STK ensures that components do not shift prior to curing, improving build quality. This functionality supports the process of vulcanized rubber creation, where correct alignment before curing leads to improved final mechanical integrity and reduced defects.
STK supports consistent bonding in rubber products requiring high unvulcanized adhesiveness
Rubber products that require secure temporary adhesion—such as multi‑layer assemblies, complex molded components, or bonded parts—use Acetylene Tackifying Resin STK to obtain high uncured adhesion. This tack assists in maintaining the relative positioning of parts during handling and pre‑vulcanization stages. The resin’s tackiness enables stable assembly of components destined to become vulcanized rubber, ensuring that once vulcanization occurs, the final product reflects intended alignment and structural form, without unwanted gaps, slippage, or irregularities.
