Basic introduction of gypsum construction mold silica gel:

Gypsum construction mold silica gel is a kind of two-component silicone rubber and liquid silica gel. Component A is a flowable liquid, and component B is a liquid curing agent (vulcanizing agent). After the silica gel and the curing agent are mixed, it can be quickly formed. Gypsum construction products, condensed silica gel and addition molding silica gel are all suitable. The former is the most traditional industrial-grade silica gel, and the latter is the food-grade silica gel developed in recent years. It is environmentally friendly, non-toxic and tasteless, and is used more and more. Accepted by the industry, but the price will be a bit more expensive than the former. Therefore, whether you use condensed silicone rubber to turn molds or add-molded silicone rubber to turn molds, each has its own advantages and each has its own advantages.

The main application areas of gypsum construction mold silica gel:

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

Main performance characteristics of gypsum construction mold silica gel:

①The lower linear shrinkage rate makes the silicone mold not easy to deform;

②Because low-molecular by-products are not released during vulcanization, the vulcanization is synchronized from top to bottom and from the inside to the outside, which can be deeply vulcanized, and there is no re-sticking and degradation of the mold due to the by-product small molecules that are not cleaned up;

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

④Good elasticity, easy to demold, not easy to damage the original mold, more suitable for re-molding and copying products of various sizes, complex patterns and fine shapes.

Description of the operation method of gypsum construction mold silica gel:

Gypsum construction mold silica gel is a flowable liquid silicone rubber. Generally, the hardness of the product after curing is 10-40 degrees. If customers need to make large products, such as split molds, they must use high-hardness liquid mold silicone to make the mold: On the contrary, for complex patterns and fine and tiny molds, such as potting molds, soft liquid mold silicone must be used. Let’s make a model.

The amount of curing agent added can be determined according to the actual requirements of customers, requiring fast drying and quick mold release, correspondingly, more curing agent should be added. On the contrary, if you need to release the mold more slowly, add a little less curing agent (but the curing agent should not exceed 5% at most).

Precautions for gypsum construction mold silica gel:

1. The amount of curing agent added should be determined by the temperature, and the temperature will 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 results, please store the mold for at least 24 hours before using it.
