Processing
- VINNOL® E 18/38 is typically used in dissolved form.
- Ketones and esters are the solvents most commonly used for VINNOL® E 18/38, ketones being more efficient than esters. Various glycol esters (e.g. butyl glycol acetate) and glycol ethers can also be used as solvents, their suitability needs to be checked on a case by case basis. Alcohols and aliphatic hydrocarbons do not dissolve VINNOL® E 18/38. Aromatic hydrocarbons may be combined to a limited extent with true solvents.
- VINNOL® E 18/38 can be plasticized with monomeric and polymeric plasticizers, such as phthalates, adipates, sebacates, citrates, phosphates, epoxides and chlorinated paraffins.
- VINNOL® E 18/38 is fully compatible with all other VINNOL® surface coating resins. It also combines well with many acrylic polymers and ketone resins, as well as with some epoxides. Alkyd, nitrocellulose, polyvinyl acetate and polyvinyl butyral resins are typically incompatible with VINNOL® E 18/38. We recommend to always check the compatibility of VINNOL® E 18/38 with potential blending partners.
- VINNOL® E 18/38 shows high compatibility with pigments routinely used in the coatings industry. Care must be taken when using pigments containing zinc or cadmium because these catalyze the decomposition of VC copolymers at elevated temperatures. The same applies to iron-oxide pigments.
- Despite good inherent stability, it is necessary for some applications to stabilize coatings based on VINNOL® E 18/38 against heat and/or UV light. Epoxy compounds often suffice to stabilize these coatings against low thermal impact. Where higher temperatures are involved, it is advisable to use calcium/zinc or organotin stabilizers. Outdoor applications require the additional use of UV stabilizers along with thermal stabilizers optimized for these conditions.
- To avoid risk of discoloration, contact with iron should be avoided both during preparation of the solution and during subsequent storage of the product. VINNOL®-based surface-coating resins should be stored in coated containers.

- Properties
- VINNOL® E 18/38 is a thermoplastic, physically drying binder that forms a film when the solvent contained in the formulation has evaporated.
- Like all VC copolymers, VINNOL® E 18/38 is extremely tough, showing permanent flexibility, abrasion resistance, little tendency to swell in the presence of water and low gas permeability. It is also highly resistant to oil, grease, dilute aqueous acids, alkalis and saline solutions, as well as to aliphatic hydrocarbons, such as white spirit, and alcohols.

Storage & Handling
- Shelf Life
- 12 Months
- Storage Information
Store VINNOL® E 18/38 under dry conditions and at room temperature (below 25°C). Under these conditions, the product has a shelf life of at least 12 months, from the delivery date. If the material is kept beyond the recommended shelf life, it is not necessarily unusable, but the user should perform a quality control on the properties relevant to the application.
