What is Interfill 830 Standard Part B and why choose it
Interfill 830 Standard Part B is the curing agent for the low-density Interfill 830 epoxy fairing filler system from International Náutica. It is designed for professional use and is mixed with Interfill 830 Base (YAA867) to create a fairing compound for profiling above and below the waterline on steel, aluminium and composite hulls.
When combined with Interfill 830 Base, the system provides a lightweight, easy-to-sand, impact-resistant and moisture-resistant epoxy filler that can be applied in thick layers for efficient fairing on large surfaces.

FAQ
1. What is Interfill 830 Standard Part B used for?
Interfill 830 Standard Part B (YAA868) is the curing agent that must be mixed with Interfill 830 Base (YAA867) to create the Interfill 830 epoxy fairing filler used for profiling and fairing marine hulls.
2. What is the correct mixing ratio with Interfill 830 Base?
The Interfill 830 system is mixed at 1:1 by volume (base to curing agent) as supplied. Mix thoroughly to a uniform colour before application.
3. On which substrates can the mixed Interfill 830 system be used?
When used as specified, the Interfill 830 system can be applied over cured epoxy primers and fillers on steel, aluminium, rigid wood and GRP/composite substrates that are clean, dry and correctly prepared.
4. How thick can I apply the mixed filler in a single coat?
The recommended maximum wet film thickness for the mixed Interfill 830 system is 20,000 microns (approximately 2 cm) per coat using a trowel or batten.
5. What is the pot life and sanding/overcoating time?
Pot life, sanding and overcoating intervals depend on temperature and are defined for the mixed Interfill 830 system, not for Part B alone. Consultar ficha técnica del fabricante.
6. Do I need a specific primer under Interfill 830?
Yes. Steel and aluminium should be primed with suitable epoxy primers such as Intergard 269 or Interprime 820. Bare rigid wood substrates should be primed with Interprime 820. GRP/composite should be prepared and primed as specified in the system guidelines.
7. Can I use Part B with other epoxy fillers or bases?
No. Interfill 830 Standard Part B is designed for use only with Interfill 830 Base (YAA867) at the specified ratio.
8. Is Interfill 830 Standard Part B suitable for consumer use?
No. The curing agent and the Interfill 830 system are intended for professional use only.
Section 14 – Transport information
According to the safety data provided for Interfill 830 Curing Agent (YAA868):
- ADR/RID: Not dangerous for transport.
- IMDG: Non hazardous.
- ICAO/IATA: Non hazardous.
The product should nevertheless be transported in securely closed original containers, kept upright, and protected from damage and extreme temperatures. Avoid release to drains, watercourses or soil in case of accidental spillage.
Section 8 – Individual protection measures
Personal protective equipment and exposure control recommendations for handling Interfill 830 Standard Part B (YAA868) are as follows:
- Ventilation and engineering controls: Provide adequate general and, where practical, local exhaust ventilation to keep airborne concentrations below occupational exposure limits.
- Respiratory protection: If exposure may exceed limits, use approved respiratory protection. When applying by spray, use a mask with combined organic vapour and particulate filters (for example, A2-P2 type) or air-fed respiratory equipment in confined spaces. For brush or roller application, use an organic vapour filter (A2) where needed.
- Hand protection: Wear nitrile gloves during mixing and application. Gloves should comply with relevant standards and be replaced regularly or immediately if damaged.
- Eye and face protection: Use suitable eye protection such as chemical splash goggles, and where splashing is likely, a face shield.
- Skin and body protection: Wear protective clothing covering arms and legs to prevent skin contact. No skin should be left exposed.
- Hygiene measures: Do not eat, drink or smoke in application areas. Wash hands, forearms and face thoroughly after handling and before breaks. Remove contaminated clothing and protective equipment before entering eating areas and wash them before reuse.
