Description:
PLASTICRETE P-CAST A02 is a water based acrylic resin that reacts with the special filler forming a solid mass. The system hardens at room temperature and in a short time the material reaches mechanical properties much higher than the normal gypsum based products. 50% of the final mechanical performances are obtained after 15 hours at 20°C only. The cured product has a limited porosity and low water absorption. The Plasticrete can be additivated with iron oxide based pigments, with aluminium powders or inert fillers to obtain the preferred finishing effect. The addition of fillers reduces proportionally the mechanical properties of the material.
Application:
For small or large size architectural elements, flame resistant, low or high density, sculptures reproduction. It is possible to obtain materials that look like natural stones or metals through the addition of the correct fillers.
Processing method:
Mass casting or as an alternative, for stratification of glass fabrics or if additivated with glass chopped strands, for brushing up to the desired thickness. Room temperature curing.
Instructions:
- Weigh the liquid (resin), after rehomogenization, in a clean vessel.
- Add the filler in the correct ratio and mix slowly with a mixing whisk to facilitate the powder dispersion.
- Wait 1 minute before starting the mixing, manually or mechanically at medium speed (1000-2000 rpm) with whisk or elicolidal spindle for 2 minutes until a complete homogenized material is obtained. We suggest to filter the material on a large hole size filter (1 - 2mm) to separate eventual residual lumps above all if the casting is directly on the figure.
The mixture can be:
- cast directly on the shape;
- applied in several layers by brushing if it is additivated with the following % : liquid P-CAST A02 50 parts + powder P-FILLER ART 100 parts + glass chopped strand 6 parts to obtain fibrous pastes with different consistency;
- used to impregnate large filling glass fabric (our D5 glass cloth) until the desired thickness is obtained.
Increasing the amount of resin to 55 parts for 100 parts of filler it is possible to lower the viscosity, extend the working time but also increase the time necessary for complete drying. Where as, the lowering of the amount of resin to 45 parts for 100 parts of filler increases the viscosity, reduces the working time, speeds up the complete drying of the product and gives a less porous material, particularly suitable for external applications.
If the product is applied by stratification it is advisable to apply as a surface layer using as a thickening agent Plasticrete P-Tix
