Description
Additional information

RENIA – Hardener C – Polyisocyanate Hardener & Crosslinking Agent

Renia Hardener C is an advanced polyisocyanate crosslinking agent developed in Germany by Renia GmbH. It is engineered to transform single-component contact adhesives into high-performance 2-component bonding systems.

By creating dense molecular crosslinks within the adhesive matrix, Härter C significantly enhances bond strength, elevates thermal stability beyond +120°C, and provides unmatched resistance against plasticizer migration, oil, fuel, grease, and moisture.

Key Highlights & Advantages:

Extreme Heat Resistance: Elevates the thermal limits of contact adhesives, preventing bond failure on sun-exposed automotive dashboards, headliners, and boat decks.
Blocks Plasticizer Migration: Essential for bonding oily leathers, rubber, and plasticized PVC (vinyl) — prevents the adhesive from softening, liquefying, or peeling over time.
Universal Compatibility: Fully compatible with all Renia solvent-based adhesives (Colle de Cologne, Multi-Colle, Syntic-TOTAL, Top-Fit, and ReGuMet).
Chemical & Moisture Immunity: Imparts superior resistance to fuel, engine oil, water, perspiration, and harsh weather exposure.
Amber Glass Protection: Packed in a light-blocking glass bottle with an airtight seal to preserve polyisocyanate reactivity.

Recommended Uses & Applications:

Automotive & Marine Trimming: High-heat bonding of leather or vinyl wraps on dashboards, door cards, marine upholstery, engine bay sound insulation, and campervan conversions.
PVC & Vinyl Assembly: Critical additive for PVC-to-PVC bonding and adhering soft marine-grade PVC vinyls without adhesive degradation.
Footwear & Orthopaedics: Heavy-duty sole bonding on natural rubber, oily pull-up leathers, and safety workboots subjected to heat and chemicals.
General Workshop: Any high-stress application requiring permanent bond integrity under extreme mechanical and environmental conditions.

Mixing Ratio & Application Guide:

1. Dosage: Add 5% to 10% of Renia Hardener C into the contact adhesive (e.g. 50 ml to 100 ml of hardener per 1 Litre of glue).

2. Mixing: Stir the mixture thoroughly for at least 30–60 seconds to ensure homogeneous crosslinker distribution.

3. Pot Life / Working Window:

• Once mixed, the 2-component adhesive remains usable for 4 to 6 hours.

• Note: Adding hardener reduces the open time of the adhesive by approximately 30–40%.

4. Application: Apply, dry, and press the mixed adhesive following the standard instructions of the base cement.

5. Curing: Initial green strength allows immediate processing. Full chemical crosslinking and maximum thermal resistance are achieved within 24 to 48 hours.
