TBL-8789 series is a highly transparent, high-strength, low-viscosity two-component addition-type room temperature vulcanized fumed type RTV2 silicone rubber, using imported fumed high-specificity white carbon black.

After the two components are mixed, the viscosity is moderate, vacuum degassing is possible, and the storage time at room temperature is long. The material shrinkage rate is extremely small during curing. The product can be prepared into various highly transparent products through manual or machine mixing of the two components, vacuum degassing, and molding.

Features and Benefits

• Low viscosity, excellent bubbling removal

• High transparent

• Excellent tear -resistant strength

• Low linear shrinkage

• Temperature -resistant -50℃~200℃

• Platinum vulcanization is environmentally friendly and non -toxic, and passed the FDA certification

• Curing conditions can be selected, which can be cured at room temperature or high temperature

Application

• Jewelry molds

• Transparent insoles 

• Room temperature pacifiers, medical cathers

Instructions:

• Manual operation: Prepare the materials of components A and B, accurately weigh the two components A and B with a mass ratio or volume ratio of 1:1, stir the A and B components evenly by hand or machine, and place them in a vacuum. The bubbles are released in the box, and the bubbles can be released for 3 to 5 minutes, and then poured into the electronic components that need to be sealed, and cured at room temperature or by baking.

• Machine operation: Put the A and B components into the A and B cylinders of the two-component filling machine respectively, and then adjust the machine parameters to ensure the quality of the A and B components discharged from the machine or The volume ratio is 1:1, then turn on the machine, mix components A and B to the mixing head and stir evenly, inject them into the electronic components to be potted, and cure at room temperature or heating.

Precautions

This product is an addition type silicone rubber with platinum vulcanization system. The following substances will affect or hinder the curing of the product:

• Compounds containing heavy metal ions such as tin (Sn2+), lead (Pb2+), mercury (Hg2+);

In recent years, liquid silicone rubber has become a popular choice for keypads and other items in high-risk areas such as hospitals. This material comes in various forms such as sheets, rolls, slabs and pastes. Because it has the added benefit of being able to stretch, liquid silicone rubber is able to bond with hollow plastic parts such as air-compression valves and air ducts to provide a secure, flexible, and lightweight support. It also has many other uses in industries where stability is critical, such as those involving the construction and transportation of ships, trains, and trucks.

 As liquid silicone rubber ages, it changes from a solid to a semi-solid state. This means that while it still provides an effective barrier to abrasion, it can now also be used to fill in holes and cracks. For instance, if a road is being repaired, the road-repair contractor can put down a sheet of liquid silicone rubber and fill in the area by driving over it with a piece of equipment. The thickness and pliability of this product allows it to mold itself to any shape. By carefully thinning out the liquid silicone rubber, it can then be applied to a variety of other items including air compressors, pipe fittings, and pipes or tubing to provide a wide range of filling options.

When selecting liquid silicone rubber, it is important to determine the level of elasticity required for the application in question. As it is solid, it will not expand unless stretching. This makes it ideal for use in a variety of key lock applications where a thin, flexible layer is desired such as in automobile windshields where it provides excellent structural support. It is also used to fill in voids between holes in the vehicle as well as in the engine compartment. Liquid rubber is also often used to fill in scratches on cars and boats.

The benefits of liquid silicone rubber for keypad printing are fairly self-explanatory; it is extremely durable and elastic, and it is both cost effective and flexible. Because it is able to expand to fill in gaps, it does not damage the surface to which it adheres. As long as the correct amount of silicone is used, it will prevent surface damage to itself as well as prevent the spread of mold. This can help make it an excellent choice for key pad printing where aesthetic appearance is secondary to functionality.

Of course, like all rubber products, liquid silicone rubber for keypad printing will not remain smooth and supple forever. Eventually, the expanded polymer will begin to strain and warp. When this occurs, it is important that you remove the rubber from the keypad in question before it begins to degrade. If you attempt to force the substance, it will result in cracking and a release of harmful bubbles that contain high levels of adhesive.

Fortunately, this is an uncommon problem with liquid-filled keypads. More often, the material will simply crumple when pressed. If you find that your keypad material is beginning to tear at the edges, it may be time to replace it with another type of keypad material. In many cases, you can find replacement keypads online at affordable prices.
