How printing silicone rubber

1. Firstly,clean the mold with detergent, and dry up the mold by a piece of cloth or an air gun and then coat the mold with a layer of release agent.  2. The normal proportion between the pad printing silicon and the silicone oil depends on the requirements of the customers. If pattern with big area to be printed, a soft silicon pad is needed and the amount of silicone oil is increased. Contrarily, if a silicon pad with high hardness is needed, the silicone oil should be added less or not . The hardness of general pad printing silicone rubber is approximate of 15A°~-25 A°; if too much silicone oil is added, the silicon pad is so soft that the printing times is limited, the molecular weight of the silicon will be damaged by the silicone oil no matter how superior quality the silicon is, thereby bringing about abrasion intolerance, solvent intolerance and ageing.   3. General mixing proportion is as follows: add 30g silicone oil into 100g silicon with the hardness of the silicon pad being 20A°, which is suitable for the pad printing for alloy car and products with small patterns and contact areas. If a big pressure contact surface or a soft silicon pad is needed, the mixing proportion between the silicon and the silicone oil can be 100:30-100:50. But please note that the more amount of silicone oil added, the softer the silicon pad, which will reduce times of pad printing, abrasion resistance and solvent resistance. In addition, the times of pad printing will be correspondingly reduced which will cause increased cost and material waste.   4. The amount of the curing agent and the chemical reaction with the silicon is as follows: mix 100g silicon and 50g silicone oil sufficiently and evenly, then add the curing agent which is 2%-3% of the total weight of the silicon and the silicone oil, mixing for 2-3 minutes, and then deair to remove the air bubbles . The time of deairring generally does not exceed 10 minutes. If the deairing time is too long,it may cause fast curing of the silicon and impact the quality of silicon.

How to use Clear silicone sealant

Clear silicone sealant has been used for several years to close windows and doors after installation. It is just a good product to use when waterproofing an undertaking. It isn't challenging to use, and, using easy steps, you may find that you've be a pro. Remember, though, that silicone sealant bring various applications that require a definite, waterproof seal. Instructions 1. Insert the clear silicone sealant into the caulking gun. The caulking gun can be a round, metal cylinder that may get a tube of silicone sealant. It has a metal rod inside that pushes through the rear in the tube of silicone sealant and forces the sealant away from an advice on no more the silicone tube. By pressing a handle on no more the caulking gun, you'll be able to control the volume of silicone that is dispensed. 2. Silicone TubeTrim a smaller piece (about 2 inches long) off the plastic tip located after the sealant tube. The tube is approximately 1/8 inch wide in the very tip, plus it flares over to 1/2 inch at where it attaches to the cylinder of sealant. Begin with a tiny piece and then come up to the desired hole size as you need to. 3. Poke a protracted nail up through end of the tip and pierce the foil seal located in the tip possibly at the foot of the sealant tube.4. Press leading against the place to be sealed and gently squeeze the handle located near the top of the caulking gun. An individual will be finished with the applying, release the pressure in the caulking gun by disengaging the metal rod at the handle. Failure to do this will lead to sealant leakage. 5. Smooth the bead of silicone sealant out with your finger. Cleanup any excess silicone having a rag and paint thinner

Silicone is employed within the automotive field

In the automotive field , silicone grease is usually utilized as a lubricant for bake components since it is stable at high temperatures , is not water-soluble which is far less likely than othe lubricants to foul . Automotive spark plug wires tend to be insulated by multiple layers of silicone to stop sparks form jumping to asjacent sires , vausing misfires . Siliocne tubing is sometimes used in automotive intake systems (specifically engines with forced- induction ). Sheet silicone can be used to manufacture gaskets used in automotive engines , transmissions along with other applications . Automotive body manufacturing plants and paint shops must avoid the existence of all silicones , since they may cause "fish eyes " small , circular crates that can be found in the tip . Additionally , silicone compounds for example siliucone rubber are employed from the automotive industry for airbags as xoatings and sealants . The prime strength of silicone rubber causes it to be an ideal adhesive/sealant for hath impact airbags.

High temperature resistance

If you are manufacturing or designing a product that must retain its physical properties through heat, cold, or extreme shifts in temperature, rely on the proven performance of silicone from Hong Ye Technology. Silicone elastomers have a very wider operating temperature range than most organic elastomers. They: Will be more resistant against degradation %u2013 loosing physical property performance when exposed to high or low temperatures Do not become soft and irreversibly deform when afflicted by temperatures >100°C(>212°F) Retain their natural flexibility and attempt to perform at low temperatures that might cause most organic elastomers for being brittle Resist compression set at both low and high temperatures Maintain their properties longer at higher temperatures Meet a variety of global industry specifications and gratifaction tests Silicone elastomers could be tailored or custom compounded to meet a variety of temperature resistance requirements, including high heat, heat aging, fire resistance, and flame retardancy.
