plaster building mold silicone

Product serial number
Product description

Basic introduction of gypsum building mold silicone :

Gypsum building mold silicone is a kind of two-component silicone rubber and liquid silicone. Component A is a flowable liquid, and Component is a liquid curing agent (vulcanizing agent), which can be rapidly formed after the silicone and curing agent are mixed. Condensed silica gel and addition silica gel are very suitable for mold turning of gypsum building products. The former is the most traditional industrial-grade silica gel, while the latter is food-grade silica gel developed in recent years. It is environmentally friendly, non-toxic and tasteless, and is being used more and more accepted by the industry, but the price will be a little more expensive than the former. Therefore, whether it is using condensed silicone rubber to overturn the mold or the addition type silicone rubber to overturn the mold, each has its own advantages, and each can take its own advantages.


Main application fields of gypsum building mold silicone

Suitable for all kinds of gypsum handicrafts, gypsum decorative building materials, architectural decoration handicrafts, gypsum cement products, Roman columns, cultural stones, background walls, garden decorations, garden stone potted plants, stone carving figures and other architectural and garden handicrafts. It can be used for batch overmolding of resin, polyurethane, glass resin and other products .


Main performance characteristics of gypsum building mold silicone :

①Lower linear shrinkage rate, the silicone mold made is not easy to deform;

②Because no low-molecular by-products are released during vulcanization, they are synchronized from top to bottom and from inside to outside during vulcanization, which can be deeply vulcanized.

③It has better hydrolysis resistance, better strength and better fluidity.

④Good elasticity, easy to demould, not easy to damage the original mold, more suitable for replicating products of various sizes, complex patterns and fine shapes.

Instructions on the operation method of gypsum building mold silicone :

Gypsum building mold silica gel is a fluid liquid silicone rubber. Generally, the hardness of the product varies from 10 to 40 degrees after curing. If the customer needs to make large products, such as splitting molds, it is necessary to use liquid mold silicone with high hardness to make molds. On the contrary, for complex patterns and fine and tiny molds, such as filling molds, soft liquid mold silicone must be used. to make a model.

The amount of curing agent added can be determined according to the actual requirements of customers, requiring rapid drying and rapid mold release, and correspondingly more curing agent should be added. Conversely, if you need a slower demoulding, add a little less hardener (but no more than 5% hardener).

(Note: The company's products do not advocate adding silicone oil, special soft silicone molds  or complex patterns and precision small, you can add 5%-10% silicone oil to adjust the softness of the silicone mold for demoulding.)



The main technical performance parameters of Hongye Silicone -Mold Silicone HY are as follows:

Remarks The above parameters are only the parameters of this model HY-630, and the parameters of other models are not shown; if you have special requirements, please contact our company; after curing, the hardness, viscosity, and operating time can be specially adjusted and provided according to customer needs. 


Gypsum building mold silicone precautions :

1.  The amount of curing agent should be determined according to the temperature, and it should be reduced if the temperature is high. If the curing agent is used too much, the mold will become hard and brittle; if the curing agent is used too little, the operation time will be prolonged.

2. In order for your silicone mold to achieve the best use effect, please store the mold for at least 24 hours before use.
