Addition Cure Silicone Rubber for Rapid Prototyping

HY- E642 Addition Molding Silicone

Description of Addition Cure Silicone Rubber for Rapid Prototyping:

HY- E series addition molding silicone is generally named two-components silicone rubber, Part A and part B. It features an exceptional fluidity and good operability. The mixing ratio is 1:1 (10:1),mainly be suitable for making molds application.

Applicationsof Addition Cure Silicone Rubber for Rapid Prototyping:

HY- E series addition molding silicone could be mainly used for making concrete stones, wax molds, PU molds, resin molds, gypsum casting, candle molding and chocolate , candy and any other FDA food product mold making,prototyping etc.

Advantages  of Addition Cure Silicone Rubber for Rapid Prototyping:

*low shrinkage (less than 0.1% )

*high tensile and tear strength with high copy times

*easy for operation (mixing ratio at 1:1 /10:1)

*very good flow and easy for pouring operation

*Fast and non-shrink cure at room temperature which can be accelerated considerably by the application of heat

*Outstanding resistance to concrete

Technique Data Sheet of HY-E642 addition cure silicone for rapid prototyping:

(Note: Other hardness is adjustable)

Operation instruction of HY-E Series molding silicone for rapid prototyping:

1. Pls clear the model and tool totally before operation to prevent cure inhibition.

2.Weigh the two part correctly by electronic weight in two separate container .

3. Mixing the two part in 1:1/10:1 and stir part A and part B evenly in 2-3 minutes .

4.And get the mixture for vacuum-pumping for de-air the bubble in around 2-3 minutes . (If there is no vacuum machine, pls pour the mixture carefully and slowly down the side of the mold frame so that less bubbles caused)

5. Enclose the product (the original model) with four plastic plates or wooden plates.

6. Clean your products and brush a layer of release agent(detergent or soap water) on your product.

7. Pour the vacuumed mixture into the model frame from the side of the mold frame.

Warm Tips for Rapid Prototyping of Silicone Rubber:

As our E-series silicone is platinum cure silicone , which is very easy to cause cure inhibition , so pls do remember thoroughly clean the model and tool before operation . Besides , pls avoid the liquid E-series silicone contact or mix with the following material , otherwise the silicone won’t be cured:

1. Liquid condensation silicone ( condensation silicone not completely cured or organic tin compounds )

2 .Sulphur, sulfide and sulfur rubber materials.

3. Amine compounds as well as contains the amine materials.

4 .Pewter solder flux.

Shelf Life of Silicone Rubber for Rapid Prototyping:

8-10 months when stored under 24°C in original unopened packages.
