In the field of silica gel, there is a kind of hand-feeling oil, which is mainly used for some products to achieve the desired hand and coated on the product. It is also called silica matting oil and silica matt oil. In fact, many products of silicone type require spray one. The layer feels oil, and the purpose of spraying the oil is basically the same.
The advantages of feel oil:
First, it can increase the smoothness of the surface of the silicone product, feel the delicate touch, and eliminate the feeling of the silicone after the molding.
Second, the silica gel product is easy to electrostaticize during the rubber mixing and molding process, so that it is easy to adsorb dust, and it can reduce static electricity after spraying a layer of hand oil.
Third, the feel of the oil has a friction-resistant effect, with wear resistance, is the longer life of the silicone product.
Classification of hand oil:
Surface effect: 1, frosted hand oil;
2, matte hand oil;
3, glossy touch oil.
Wear resistance: normal type and high wear type;
Curing temperature: high temperature curing and low temperature curing;
Construction process: Injecting oil and silk screen feel oil.
The following is a detailed introduction to the practical application of high and low temperature curing hand oil
The low temperature type feel oil has a curing temperature of 80-120 degrees and a baking time of no more than 30 minutes. The main target product is P+R product. Because the temperature of the plastic+silicone product is relatively low, the plastic will be deformed when it exceeds 120 degrees. Therefore, only choose low temperature feel oil;
High-temperature hand-applied oil is widely used, and the curing temperature is generally 180-200 degrees, and the time is 10-20 minutes.
