Renia Hardener C 100ml Bottle

Renia Hardener C – 100ml Bottle.

Professional Crosslinking Agent for PU and Contact Cements.

Renia Hardener C is a high-performance crosslinking additive formulated to significantly enhance the bond strength, temperature resistance, and durability of Renia polyurethane (PU) and polychloroprene (neoprene/contact) adhesives. This hardener is a must-have for professional leatherworkers, shoemakers, and manufacturers working with high-stress, high-performance leather bonding applications.

When mixed into compatible adhesives, Hardener C initiates a chemical crosslinking reaction that dramatically boosts adhesion—especially on oily, synthetic, or rubberized surfaces.

Key Features:

• Crosslinking Booster: Strengthens adhesive bonds by chemically linking adhesive molecules.
• Enhanced Heat & Water Resistance: Increases resistance to high temperatures and water exposure.
• Improved Long-Term Durability: Reduces risk of delamination or adhesive failure over time.
• Ideal for Demanding Applications: Recommended for high-wear leather goods, technical footwear, synthetic materials, and bonding oily leathers.

Specifications:

• Volume: 100ml (approx. 3.4 fl oz).
• Color: Clear, low-viscosity fluid.
• Mixing Ratio: Typically 3–5% by weight of adhesive.
• Shelf Life: Use mixed adhesive within a few hours, as pot life is reduced after addition.
• Packaging: Sealed glass bottle with resealable cap.

Application Instructions:

• Mixing: Add 3–5% Renia Hardener C to your chosen PU or contact adhesive (e.g., Renia Colle de Cologne, Renia Syntic Total, etc.).
• Stir Well: Mix thoroughly to ensure uniform distribution of the hardener in the adhesive.
• Use Promptly: After mixing, apply the adhesive within its reduced pot life (usually 4–8 hours depending on conditions).
• Apply Normally: Spread adhesive on both surfaces, allow appropriate open time, then bond under pressure.
• Note: Always mix only the amount of adhesive you plan to use immediately, as hardener reduces shelf life significantly once combined.

Ideal For:

• Leather and synthetic shoe soles.
• Technical gear or outdoor leather goods.
• Belts, straps, bags, and items exposed to heat or moisture.
• Bonding rubber, oily leather, or high-flexibility synthetic materials.

Renia Hardener C transforms standard adhesives into high-performance bonding systems. For professionals who demand exceptional strength, resistance, and reliability in their leatherwork, this hardener is an essential upgrade to your adhesive toolkit.
