Abstract:
A research program is underway with the main objective of promoting the change between vegetable and mineral oil-based release agents. The classification of these products would be clarified in terms of biodegradability and toxicity. The technical performance of the vegetable oil-based products (VERA) is investigated and advice provided within the construction industry on working procedures. These alternative products have important advantages in aspects such as working conditions, safety, environmental impact, economy, and technical production performance. Tests carried out to evaluate the technical performance of VERA are also described.
