GRAVICOL 2397-TC PUTTY WITH FIBER

What is GRAVICOL 2397-TC PUTTY WITH FIBER and why choose it

GRAVICOL 2397-TC PUTTY WITH FIBER by Laminados y complementos is a pre-accelerated bonding paste based on unsaturated polyester resin, reinforced with fibers. It is designed for structural and semi-structural bonding of composite parts, gap filling and surface sealing where a smooth, easy-to-apply paste with good mechanical strength and reduced shrinkage is required. Some of the information below is based on publicly available technical data and distributor descriptions and may not be fully up to date or complete.

Main features

• Semi-flexible bonding putty: Suitable for dynamic bonding applications where the bonded assembly is subject to vibration or slight movement.
• Reinforced with fibers: Contains fibers that improve mechanical strength and make it suitable for bonding joints with significant gaps between composite parts.
• Pre-accelerated polyester resin: Cures at room temperature (approx. 15–25 °C) when mixed with MEKP peroxide, making it ideal for workshop and shipyard environments.
• Very smooth, creamy consistency: Easy to apply and spread with a spatula over vertical and horizontal surfaces.
• Low shrinkage during cure: Helps maintain the dimensional stability of the bonded parts during the curing cycle.
• Good adhesion on composite substrates: Developed as a polyester adhesive for bonding and filling operations on composite laminates.
• Indicator version (TC): The TC grade includes a catalyst indicator to help visually control the mixing of paste and hardener (information inferred from manufacturer documentation and should be verified for each batch).

Technical specifications

The following technical data are summarized from distributor and manufacturer documentation and should be considered indicative, not a substitute for official product documentation.

• Chemical nature: Pre-accelerated bonding paste based on unsaturated polyester resin, reinforced with fibers.
• Appearance: Thixotropic adhesive paste / putty with fibers.
• Brand / range: Laminados y complementos – GRAVICOL series.
• Product function: Polyester adhesive for composites (bonding paste – fiber reinforced).
• Curing system: Room-temperature curing with MEKP (methyl ethyl ketone peroxide).
• Catalyst: MEK peroxide (MEKP).
• Typical catalyst dosage: Approx. 1–2 % MEKP by weight on base paste, with distributor information often referencing around 1 % by weight. Exact dosage must be adjusted according to ambient temperature, mass and working time requirements and verified in the current technical documentation.
• Recommended application temperature: Designed for workshop conditions around 15–25 °C (value indicative from manufacturer documentation and not individually verified for this listing).
• Packaging / capacity: Container of approx. 25 kg (value taken from distributor description and subject to possible changes by the supplier).

Applications and use cases

According to available manufacturer and distributor information, GRAVICOL 2397-TC PUTTY WITH FIBER is suitable for a wide range of bonding and filling operations on composite parts:

• Bonding of composite components: Intended for bonding operations on polyester and other compatible composite laminates in marine, industrial and general composite fabrication.
• Gap filling and surface filling: Suitable for filling gaps between mating parts and correcting surface irregularities before subsequent laminating or finishing operations.
• Sealing operations: Can be used as a sealing putty in areas where a fiber-reinforced bonding paste is required.
• Laminating aid: May be used as an aid to lamination to build up local thickness or achieve smoother transitions between laminate sections (information derived from manufacturer technical descriptions and should be contrasted with current instructions for use).
• Dynamic bonding applications: Described as a semi-flexible bonding putty for applications where the assembly may be subject to dynamic loads, vibrations or small deformations.

For all applications, substrates should be properly prepared (sanding, cleaning and degreasing) following the most recent official instructions for the product.

FAQ – GRAVICOL 2397-TC PUTTY WITH FIBER

1. What type of product is GRAVICOL 2397-TC PUTTY WITH FIBER?

   It is a fiber-reinforced bonding paste based on unsaturated polyester resin, designed for bonding, gap filling and sealing operations on composite parts.

2. How is the product cured?

   The paste cures at room temperature after adding MEKP (methyl ethyl ketone peroxide) hardener. The typical indicated dosage is around 1–2 % MEKP by weight on the base paste, but the exact amount must always follow the most recent official instructions.

3. What is the consistency of the paste?

   It has a very smooth, creamy consistency with thixotropic behavior, which makes it easy to apply with a spatula even on vertical surfaces, according to distributor descriptions.

4. On which substrates can it be used?

   Available documentation describes it as a polyester adhesive for composite laminates. Before use on any specific substrate or in contact with foodstuffs, the suitability and any regulatory requirements must be checked in the official product documentation.

5. What is the usual packaging size?

   Distributors commonly list GRAVICOL 2397-TC PUTTY WITH FIBER in containers of around 25 kg. This may vary by market or supplier.

6. Can it be used for very thick bonding lines?

   Some public descriptions refer to its suitability for joints with significant gaps, while also noting limitations for very thick bonding applications. The maximum bond line thickness and any restrictions should be confirmed against the latest technical instructions.

7. Is the information here a substitute for the official technical data sheet?

   No. The data provided are a summarized, unverified overview based on publicly available sources and may not reflect the latest version of the product. This description does not replace the official technical and safety documentation supplied with the product.

8. Does the product contain a catalyst indicator?

   The TC grade is described in manufacturer information as containing a catalyst indicator, but this point has not been individually verified for every packaging configuration and should be confirmed in current product documentation.
