1. Model Preparation Foundations The release agents are ready-to-use and can be painted or sprayed. For a safe release 2 - 3 layers are to be applied. 1.2 Non-absorbing surfaces Before application of a following layer the preceding one must be completely dry. 2. Front Layer (pouring technique) Properties Preparation of the foundations according Layer thickness depending on the case of RECKLI PUR Compound D 40 are twocomponent liquid resins curing nearly free Consumption: Approx. 1.4 kg/l volume of shrinkage.

4. Bonding Layers Foundation Working steps 4.1 flexible front layer The bonding layer's function is to form a strong firm bond between the cured, ela- stic front layer of RECKLI PUR Elastomer or RECKLI PUR Elastomer thix and the backing. The best bonding values are achieved, if glass fibres are added to and mixed with RECKLI Construction Resin EP or RECKLI Epoxy PB until there is a pasty consistency like sauerkraut. This pasty mass is manually applied onto the front layer, whereas the hands are to be protec- ted by rubber gloves. The backing material Epoxy PB approx. 30 - 35 minutes (200 g)...

7. Gypsum Release Agents for Block-moulds 7.1 RECKLI Gypsum Release Agent GTM 7.2 RECKLI Gypsum Release Agent GTM-VB Water-based, release agent with only little Like 7.1 with improved water absorption of affects to the environment. It is used for release between block-mould surfaces made of RECKLI PUR Elastomers, RECKLI silicone rubbers or RECKLI epoxy resins and liquid plaster of Paris. When this release agent is used, there is no swelling of the block-mould surfaces. The absorption capacity of the gypsum potter’s mould is hardly affected.
