描述

Introduction of Resin Craft Mold Silicone:

Resin craft mold silica gel, that is, special mold silica gel for resin crafts, is a kind of condensed liquid silicone rubber. Component A is a flowable liquid, and component B is a curing agent (vulcanizing agent). After the two are mixed, they can be quickly formed, and the operation is simple.

 

Industry use of resin handicraft mold silicone:

Suitable for the manufacture of silicone molds for all kinds of large, medium and small pieces, fine patterns or complex resin handicrafts, such as POLYSTER, EPOXY, Pu resin and other craft gifts, mold making of products with fine patterns , It can also be used for complex molds and precision mold manufacturing of lighting, candles, handmade soaps and other handicrafts.

 

Advantages of resin craft mold silicone:

①High temperature resistance, generally 180℃-300℃, if special reagents are added, it can withstand higher temperatures, because the unsaturated resin will release a lot of heat during the curing process, which is easy to damage the silicone mold. Therefore, the advantage of Hongye silicone is more Good high temperature resistance, which can greatly save production costs;

②The viscosity of the liquid silicone, the hardness after curing of the silicone, the operating time and curing time, the color, etc. can be adjusted according to customer requirements, and the silicone rubber can be customized for you;

③The shrinkage rate is low, the shrinkage rate of condensed silica gel is less than 0.3%, and the shrinkage rate of addition molded silica gel is less than 0.1%;

④The tensile force and tear resistance are better, and the silicone mold made is not deformed and more durable, so the number of mold turns is also higher.

Description of the operation method of resin handicraft mold silica gel:

If customers need to make large products, such as split molds, they must use high-hardness liquid mold silicone to mold: On the contrary, for complex patterns and fine and tiny molds, such as overmolds, 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).

 

The reaction of the ratio of silica gel and curing agent is as follows:

1. When the amount of curing agent is 1%, the colloid will still flow in 2.5 hours, and it can be demoulded in 6-8 hours.

2. When the amount of curing agent is 2%, the colloid will still flow in 50 minutes to 1 hour, and it can be demoulded in 2-3 hours.

3. When the amount of curing agent is 3%, the colloid will still flow in 28-30 minutes, and it can be demoulded in 1.5-2 hours.

4. When the amount of curing agent is 4%, the colloid will still flow in 10-15 minutes, and the mold can be demolded in 1 to 1.5 hours.
