Introduction of silica gel for resin process model :

Silica gel for resin craft models is a two-component silica gel, room temperature vulcanized silica gel, or liquid silicone rubber. It is a kind of silica gel specially used for resin craft models among Hongyejie's many mold silica gels. It is not only very suitable for resin craft models. , It is also suitable for mold opening of other products, some customers call it hand-made model silicone.

Silica gel for resin craft models Application fields :                 Silica gel
for resin craft models is widely used in various craft model mold products , such as resin crafts, cartoon character models, handmade model toys, artillery craft model toys, car models, military gift models, PC transparent Pieces, marine shell art, handicraft model making, resin handicraft model and other silicone mold making.

Features of silica gel for resin craft model :

1. It has the advantages of high temperature resistance, good tensile force, good tear strength, no deformation, etc., and can be used repeatedly for many times.

2. The shrinkage rate can reach 2/1000. If the addition type silica gel is used, the shrinkage rate is less than one of the shallow powder;

3. The hardness, viscosity, operating time and curing time of the silica gel can be adjusted according to the needs of customers, and the silica gel can be customized for you.

Hongye silica gel - resin process model with silica gel HY-620 parameters:

Remarks : The above parameters are only the parameters of this model HY-620, and the parameters of other models are not shown; if you have special needs, please contact our company; after curing, the hardness, viscosity, and operating time can be specially adjusted and provided according to customer needs.

Instructions for the use of silica gel for resin craft models :

Component A is a flowable liquid, and component B is a curing agent (vulcanizing agent), which can be quickly formed after mixing the two . Add 2%-3% of the curing agent at room temperature, and it can be operated within 30 minutes, 2-5 It will take shape in hours. For large-scale products, such as splitting molds, it is necessary to use mold glue with high hardness ; on the contrary, for complex patterns and fine and tiny molds, such as perfusion molds, soft mold glue is used for molds.

(Note: The company's products do not recommend 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.)

For the reaction of different ratios of silica gel and curing agent, please refer to:

1. When the amount of curing agent is 1%, the colloid will still flow in 2.5 hours, and it can be demolded 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 demolded in 2 to 3 hours.

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

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

Precautions for silica gel for resin process model :

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 handicraft silicone mold to achieve the best use effect, please store the mold for at least 24 hours before use.
