Addition cured silicon rubber for cement decorations
Addition cured silicon rubber for cement decorations Applications:
It mainly use for making molds for resin, gypsum and cement product with medium size.
Addition cured silicon rubber for cement decorations Typical Datasheet :
Item No | Color | Hardness (A°) | Viscosity (CS) | Tensile-strength( kgf /cm2 ) | Tear-strength (kgf /cm2 ) | Elongation-break(%) | Mixing Ratio of silicone and catalyst | Application(most for resin, gypsum and cement product to make moulds) |
E635 | Translucent | 35±2 | 8000±2000 | ≥60 | ≥13 | ≥400 | 1:1 | Most suitable for medium sized product |
Addition cured silicon rubber for cement decorations Advantages:
Flexible, high and low temperature resistance, resistance to ultraviolet radiation, environmental protection, water repellent, good air permeability, good insulation, shrinking smaller
Addition cured silicon rubber for cement decorations 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.
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.
Addition cured silicon rubber for cement decorations Package and storage :
1. 20kg or 200kg /drum.
2. It is a kind of non-dangerous goods, and it should be stored at a cool and dry place, please keep it from sun and rain.
