400 1:1 Most suitable for medium sized product Addition cure silicon rubber for artificial stone products advantages: Flexible, high and low temperature resistance, resistance to ultraviolet radiation, environmental protection, water repellent, good air permeability, good insulation, shrinking smaller Addition cure silicon rubber for artificial stone products points of attention: 1, prone to poisoning, can not mix with condensation, ionic compounds containing n, s-, p, organic matter and of sn, as, hg, ph., easy molding plastic poisoning, resulting in the phenomenon of not curing. 2, comparing with condensation cure silicone, addition cure silicone's adhesive properties to be worse. 3, addition cure silicone affect by temperature greatly when cured under room temperature. 4, addition cure silicone is easy to poisoning, please clean the tools which are used for condensation silicone rubber, so that it can avoid poisoning. Its fobidden to add the pigment or powder to addition cure silicone rubber arbitrarily, its easy to make the catalyst to be poisoning. 5, addition cure silicone rubebr has two-component, the component a and component b, please pay attention to clean the component a containers before using for the component b, and vice versa 6, in order to avoid the hardness change, we should mix the component a and component b according to its mixing ratio strictly, no atter its 1 : 1 or 10 : 1. 25kg/drum or 200kg/drum
