Addition silicone rubber for artificial stone molding

1,Description of Addition silicone rubber for artificial stone molding

Addition silicone rubber for artificial stone molding is very suitable for making silicon stone mold.

It is featured with extremely low shrinkage, good fluidity and resistance to many kinds of chemicals; This material do not release any by-product with low molecular weight during its curing process, and it's cured from top to bottom and from the inside and outside simultaneously, namely, deep curing. The E sereise platinum cured silicone will not have the problem of degradation, sticky mold surface caused by the existence of by-product of small molecules under certain conditions, (such as closed environment, high temperature). Known from our customer's feedback, it is very convenient to make cement molds, and it is a high-quality silicone for construction industries. Further more, it can be applied to make multiple piece molds for products with complex design.

2,Advantage of Addition silicone rubber for artificial stone molding

Addition silicone rubber for artificial stone molding is also featured with low shrinkage and nearly nil viscosity, good fluidity; Without releasing any by-product with low molecular weight, and it's cured from top to bottom, from the inside and outside simultaneously. It is suitable for the products with medium size or big size.

3,Applications of Addition silicone rubber for artificial stone molding

Addition silicone rubber for artificial stone molding can be used in the field of construction applications. Because the vulcanizing reactions of addition cure silicone is fundamentally different from tin cure silicone’s, it has some characteristics that the condensation cure type do not have, such as adjustable curing rate, being completely environmentally friendly, andso on. Therefore, our platinum cure silicone is particularly applicable for largestones molds, artificial stone molds, plaster and other architecture elements replication. The following is some detailed data about the performance of this model

4,Points of attention of Addition silicone rubber for artificial stone molding

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.

It’s fobidden to add the pigment or powder to addition cure silicone rubber arbitrarily,it’s 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 it’s 1 : 1 or 10 : 1.
