features description of silicone rubber for type mould:

RTV Silicone Rubber for car tire mold is white or red flowing liquid with general  hardness of 22-50A°after curing. Molding silicon rubber is a kind elastic  silicon rubber mold which features with resistance to deformation, high- temperature, acid-alkali and expansion as well as high reproduction times, good tensile strength, tear strength and elongation.

advantage ofsilicone rubber for type mould:

 Two-part silicon rubber: flowable liquid silicon and curing agent.

 Cures at room temperature within 4-5 hours.

 An exceptional fluidity and good operability, easy to demold.

operations of  silicone rubber for type mould:

(1)  Take out a certain amount of liquid silicone base (part A)from the container;

(2). Take out a certain amount of liquid silicone base (part B) from the container and mix with part A.

(3). The two components of silicone rubber must be mixed homogeneously, otherwise, it will be partly cured and solidified

(4). Deaerate in a vacuum cupboard to achieve bubble free vulcanization;

(5). Pouring the deaerated mixture over the highest point of the model to form castingmould;

(6). Demolding after the liquid silicone solidified thoroughly.

(7). The mixed liquid silicone rubber will solidified in 3-4 hours under room temperature 

FAQs of silicone rubber for type mould:

what should you do for imcomplete curing after the mold is finished?

Two causes lead to this problem:

a. Inexact mixing ratio, not to weigh following the standard ;

b. The mixture of the silicone and catalyst is not mixed evenly.

You should avoid this kind of problem ,otherwise there will be a waste of silicone mold.
