WACKER TN SILICONE RELEASE AGENT is a medium-viscosity modified functional silicone release agent in Wacker’s TN series, designed for thermal molding of rubber, plastics and low-melting nonferrous metals. It combines the advantages of silicone and mineral oils, good film-forming, low dosage, easy post-painting and printing of workpieces after release.
High efficiency & cost-saving - Excellent release effect with a small amount, reducing unit processing cost
Uniform film-forming & wide adaptability - Good film-forming performance, suitable for thermal molding molds of rubber, plastic and other materials
Good post-processing adaptability - Workpieces can be directly painted, printed and bonded after release without additional treatment
Good thermal stability & temperature resistance - Resistant to high temperature of thermal molding, stable performance and not easy to decompose
Good system compatibility & easy to add - Suitable for most molding systems, easy to disperse and add, no effect on product molding accuracy
Thermal molding of rubber products - Hot compression molding of rubber such as tires and seals, improving release efficiency and workpiece accuracy
Plastic product processing - Injection molding of engineering and general plastics, ensuring the surface integrity of workpieces
Low-melting metal molding - Die casting of low-melting nonferrous metals such as zinc and aluminum, reducing the risk of adhesion between mold and workpiece
Composite material molding - Hot press molding of fiber reinforced composite materials, suitable for multi-material composite molds
Precision parts release - Molding of precision parts such as electronic accessories, ensuring complete release of fine structures

Q1: What is the primary function of WACKER TN SILICONE RELEASE AGENT Silicone Oil?
A: It is a silicone-based release agent designed to facilitate clean and efficient demolding of cured or thermoset materials—particularly in rubber, polyurethane, and composite manufacturing—by forming a durable, low-surface-energy barrier between the mold surface and the substrate.
Q2: Is this product suitable for food-contact applications?
A: WACKER TN is not pre-qualified for direct food-contact use. Its suitability for such applications depends on final formulation, processing conditions, regulatory review by the end-user, and compliance with applicable regional food safety requirements—including migration assessments where relevant.
Q3: How is it typically applied in industrial settings?
A: It can be applied neat or diluted in compatible solvents (e.g., aliphatic or aromatic hydrocarbons), via spray, roll-coating, or wiping—depending on mold geometry and production scale. Application methods are selected to ensure uniform, thin-film coverage without pooling or residue buildup.
Q4: Can it be used with high-temperature molds?
A: Yes—silicone oils like WACKER TN generally retain release performance across elevated mold temperatures typical in vulcanization and resin curing processes, though prolonged exposure above 200 °C may affect film integrity depending on cycle time and atmosphere.
Q5: Does it require curing or post-application heating to become effective?
A: No—WACKER TN functions as a ready-to-use release agent; its effectiveness relies on physical film formation rather than chemical crosslinking. Solvent-diluted versions require only brief flash-off before molding, with no thermal cure step needed.
