What is ENVIROLINE 2405 PART A INDIVISIBLE KIT and why choose it?
ENVIROLINE 2405 PART A INDIVISIBLE KIT is the base component of Enviroline 2405, an ultra high solids, two-component hybrid epoxy lining system cured with polycyclamine technology. Designed for single-leg (single pump) application, it delivers high corrosion protection with rapid cure in a single-coat scheme. Enviroline 2405 is engineered for the internals of steel storage tanks, pipes and pressure vessels handling crude oil up to 150°C (302°F), and is also suitable for rail cars used to store and transport liquid and dry foodstuffs in compliance with United States FDA regulations.
With 96% volume solids and very low VOC, the system combines high build, excellent chemical resistance and fast return to service, reducing downtime and application costs in demanding industrial environments.

FAQ – ENVIROLINE 2405 PART A INDIVISIBLE KIT
-
Is Enviroline 2405 a single-coat or multi-coat system?
Enviroline 2405 is specifically designed as a single-coat lining system applied at 400–750 microns DFT. Stripe coats and touch-up/repair are applied within defined wet-on-wet or surface preparation guidelines.
-
On which substrates can I use ENVIROLINE 2405 PART A with its curing agent?
The system is intended for correctly prepared carbon steel substrates used in tanks, pipes and vessels. It is normally applied directly to steel and is not usually topcoated.

Section 8 – Individual protection measures
The following personal protection guidance is taken from Section 8 of the Safety Data Sheet for ENVIROLINE 2405 LIGHT GREY PART A and applies during handling, mixing and application by professional users.
Engineering controls and hygiene
- Use process enclosures, local exhaust ventilation or other engineering controls to keep airborne concentrations below any recommended or statutory limits.
- Wash hands, forearms and face thoroughly after handling, before eating, drinking or smoking and at the end of the work period.
- Contaminated work clothing should not leave the workplace and must be washed before reuse.
- Ensure eyewash stations and safety showers are located close to the work area.
Eye and face protection
- Wear safety eyewear complying with an approved standard when a risk assessment indicates potential exposure to liquid splashes, mists, gases or dusts.
- As a minimum, use chemical splash goggles; where a higher level of protection is required, use a face shield or full-face respirator.
Hand protection
- Use chemical-resistant, impervious gloves complying with EN374 or equivalent whenever handling the product.
- For prolonged or frequently repeated contact, use gloves of protection class 6 (breakthrough time >480 minutes), recommended materials: Viton or nitrile with minimum thickness ≥ 0.38 mm.
- For brief contact, use gloves of protection class 2 or higher (breakthrough time >30 minutes), recommended material: nitrile with minimum thickness ≥ 0.12 mm.
- Replace gloves regularly and immediately if damaged. The user must verify that the selected glove type is suitable for the specific working conditions.
Body and skin protection
- Select protective clothing based on the specific task and risks, and have it approved by a safety specialist before use.
- Use appropriate protective footwear and any additional skin protection measures required by the work conditions.
Respiratory protection
- Select a respirator that meets the appropriate standard or certification, based on the hazard and potential exposure.
- Respirators must be used within a formal respiratory protection program to ensure correct fit and training.
- Dry sanding, flame cutting or welding of the dry paint film can generate hazardous dusts and fumes. Wet sanding/flatting is preferred wherever possible.
- If local exhaust ventilation cannot adequately control exposure, wear a respirator conforming to EN140 fitted with a type A/P2 filter or better.
Environmental exposure controls
- Check emissions from ventilation and process equipment to ensure compliance with environmental legislation.
- Where necessary, install fume scrubbers, filters or make engineering modifications to reduce emissions to acceptable levels.
