                                                                    addition RTV silicon for molding

Main application of addition RTV silicon for molding :

• Rapid prototyping (urethane casting/silicone tooling/vacuum casting)
• Concrete moulding /cement products
• PU resin casting
• General Mouldmaking
• Superior manual mold design 

Description of addition RTV silicon for molding

RTV mold making addition silicone are generally named as two-part addition silicone rubber that vulcanises at room temperature.Part A is a flowable liquid, part B is the curing agent(platinum catalyst). It features an exceptional fluidity ,good operability,excellent physical properties and very low shrinkage. The mixing ratio between Part A and Part B can be 10:1 or 1:1.

Main properties of addition RTV silicon for molding

• almost nil shrinkage
• high chemical resistance to aggressive components of some types of resins
• good tear strength (this feature ensures higher resistance to wearing and shearing)
• high degree of precision in reproduction
• high dimensional stability over time and  non-deformability
• high resistance to high temperatures and ageing (resit to -60-200°C)
• excellent non-stick effect
• environmental, odorless and

E-620 silicone rubber standard datasheet(25°C)

Notice of addition RTV silicon for molding:

Addition silicone is forbidden to mix with organic compounds of condensation cure silicone rubber,otherwise, the silicone rubber will not cure, and also should not mix with organic compounds containing S, P, N as well as metallic salt of organic acids. It also will cause this product cure uncompletely or not cure.

Addition silicone molding process instructions:

Rapid prototyping for instance,a master model that usually originates from stereolithography or selective laser.If you make silicone molds in pouring way,please follow below steps:

Storage ,shelf life and handling precautions:

1. Shelf life can be twelve(12) months when stored at 25°C in tightly closed original packages.

2. Storage beyond the expired date does not necessarily mean that the product is no longer

usable. In this case , the properties required for the intended use must be checked for quality assurance reasons.

3,The curing agent may denature if the cap is left off after opening.Make sure to tightly seal the products prior to storage.Take particular care under conditions of high temperature or humidity.

4,If any of these products should come into contact with skin,wipe the exposed area with a cloth and then wash it thoroughly with soap.

5. This kind of product is non-dangerous product, which could be transported as general products.
