5.Attentions of rtv silicone rubber liquid for molding
(1). The curing speed of this product is closely related to the ambient temperature,high temperature fast curing, on the contrary, low temperature curing slow. Users can appropriately adjust the amount of curing agent to obtain the desired cure speed according to the ambient temperature level.
(2). If the copying original models are ceramic, 815 resin, ABS material, wood, metal and other materials, the original models surface need use a release agent or baking mold method then reperfusion mold for avoiding sticky mold nomenon.
(3). Two parts of this series of products should be stored separately sealed, placed in a cool place, avoid the sun and rain.
(4). If viscosity is increased or it has precipitation in silicone at storage period, can be used after mixing evenly, its performance unchanged.
(5). This product is non-dangerous goods, if skin the curing agent, can be cleaned with the suitable detergent and water; if splashed into the eyes, immediately wash with clean water at least 15 minutes, and consult a doctor.
