CLEANER E

What is Bostik CLEANER E and why choose it?

Bostik CLEANER E (Simson Cleaner E) is a transparent, fast-evaporating preparation and cleaning agent based on ethyl acetate. It is specially designed for cleaning and degreasing substrates before bonding or sealing with specific Bostik SMP (Silyl Modified Polymer) adhesives and sealants, as well as for removing uncured sealant and adhesive residues from tools and surfaces. Thanks to its short drying time and high cleaning power, it helps ensure optimal adhesion and a clean, professional finish in marine, construction and industrial applications.

Main features

• Fast drying: very short drying time, typically around 5 minutes at +23 °C and 50% RH.
• Effective cleaning and degreasing: removes grease, contamination and uncured adhesive or sealant residues.
• Ideal pretreatment: improves preparation of substrates prior to bonding or sealing with compatible Bostik products.
• Versatile use: suitable for various substrates such as glass, metal and teakwood deck joints.
• Tool cleaner: cleans tools used for applying uncured MS Polymer/SMP, silicone, polysulphide and polyurethane products.
• Transparent formula: clear liquid for easy visual control during application.
• Ready-to-use: supplied as a single-component liquid, no mixing required.

Applications and use cases

Substrate cleaning and pretreatment

• Cleaning and degreasing of various substrates such as glass and metal before bonding or sealing with specific Bostik products.
• Pretreatment of teakwood deck joints prior to applying Simson Prep P within marine teak deck systems.
• Degreasing and cleaning glass substrates in glazing or marine applications.

Removal of uncured adhesives and sealants

• Cleaning tools and application equipment used for SMP/MS Polymer, silicone, polysulphide and polyurethane adhesives and sealants, as long as these are still uncured.
• Removal of uncured residues from substrates before final finishing.

Typical application method

• Firmly rub the substrate with a clean, colourless, lint-free white cloth or tissue soaked with CLEANER E.
• If the substrate is heavily contaminated, repeat the procedure as required.
• For teak deck pretreatment, Prep P can be applied immediately after using CLEANER E; for other applications, allow a drying time of about 5 minutes.
• It is recommended to carry out a preliminary trial on a small, inconspicuous area to check that the substrate is not affected by the cleaner.

FAQ

1. What is Bostik CLEANER E used for?

   Bostik CLEANER E is used to clean and degrease substrates such as glass, metal and teakwood joints and to remove uncured SMP/MS Polymer, silicone, polysulphide and polyurethane adhesives and sealants from substrates and tools.

2. How long should I wait before applying adhesives or sealants after using CLEANER E?

   Allow a typical drying time of around 5 minutes at +23 °C and 50% relative humidity. For teak deck pretreatment, the next product (for example Prep P) can be applied immediately after wiping, observing the recommendations of the corresponding product.

3. Can CLEANER E remove cured sealants or adhesives?

   No. CLEANER E is intended for cleaning and removal of uncured sealants and adhesives. Cured material must be removed by mechanical means.

4. On which substrates can I use CLEANER E?

   It is suitable for various substrates such as glass, metal and teakwood deck joints, as well as for cleaning tools. Always perform a small test in advance to verify that the substrate is not damaged.

5. Is CLEANER E flammable?

   Yes. CLEANER E is a highly flammable liquid and vapour (flash point around -4 °C) and can form explosive or flammable vapour–air mixtures during use. Keep away from heat, hot surfaces, sparks, open flames and any ignition sources. No smoking.

6. What hazards are associated with CLEANER E?

   According to classification, it is a highly flammable liquid that causes serious eye irritation and may cause drowsiness or dizziness. Repeated exposure may cause skin dryness or cracking.

7. How should CLEANER E be stored?

   Store only in the tightly closed original container, in a dry, well-ventilated place at temperatures between +5 °C and +25 °C, protected from direct sunlight, heat sources and frost, and away from combustible materials, strong acids and strong bases.

8. What is the shelf life of CLEANER E?

   When stored in its unopened original packaging under recommended conditions, the shelf life is up to 12 months from the date of manufacture.

9. Can I use CLEANER E indoors?

   Yes, but only with adequate ventilation or local exhaust, and using the recommended personal protective equipment to avoid inhalation of vapours.

10. What should I do if CLEANER E comes into contact with my eyes or skin?

    In case of eye contact, rinse cautiously with water for several minutes, remove contact lenses if present and easy to do, and continue rinsing; seek medical advice if irritation persists. In case of skin contact, wash immediately with soap and plenty of water and remove contaminated clothing.
