AS 40 is a translucent addition-crosslinking silicone rubber. Addition polymerization systems are of the highest quality. They offer excellent dimensional stability, low shrinkage and superior chemical resistance. <\/span><\/p>

The choice of a polyaddition silicone is particularly recommended when the mold needs to withstand a high number of runs.<\/span><\/p>

Its high mechanical strength makes it particularly suitable for industrial-grade molds.<\/span><\/p>

Its base is non-toxic and mixes easily with the corresponding catalyst in a 1:1 ratio.<\/span><\/p>

This silicone can be used to make molds for casting polyester resin, epoxy, polyurethane, plaster, wax, etc., and low-melting metals.<\/span><\/p>

Their high resistance to alkaline constituents also makes them suitable for concrete casting.<\/span><\/p>

AS 40 hardens at room temperature; the higher the room temperature, the faster the setting time.<\/span><\/p>

All our silicones in the “AS” range can be thickened by adding our THIXO silicone polyaddition. The resulting paste texture can be applied to vertical elements with a spatula. <\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

In a clean, dry container, weigh out the quantity of silicone required and calculate a 1:1 addition of catalyst (e.g.: 100gr base + 100gr catalyst).<\/span><\/p>

Using a spatula, thoroughly mix the two components until a homogeneous paste is obtained; using a mechanical mixer, keep at low speed (300 to 500 rpm) for 2 to 3 min. and keep the mixer head in the silicone to limit the incorporation of air bubbles. <\/span><\/p>

After checking that the formwork is watertight, pour the silicone mixture onto the model to be reproduced.<\/span><\/p>

Aim for the lowest point and pour the silicone in a thin vein.<\/span><\/p>

The first coat can be applied directly with a brush, then the rest of the mold can be filled.<\/span><\/p>

Vacuum preparation is possible at a pressure of 0.85 bar for a maximum of 3′.<\/span><\/p>

Demoulding can take place after +\/- 6h of hardening at room temperature. The longer you wait before unmolding, the more time the silicone will have had to reach its optimum mechanical properties. In the case of a low-melting metal casting, post-firing is recommended. <\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
