What is RTV sealant

Silicone rubber is an artificial elastomer or a material that has both liquid and rubber characteristics. According to different curing forms, silicone rubber can be divided into four main types: RTV (room temperature vulcanization); HTV (high temperature vulcanization); HCR (high concentration rubber); LSR (liquid silicone rubber).

What is RTV Sealant

RTV sealant is a type of silicone that cures at room temperature. The word RTV stands for Room temperature Vulcanizing. This type of sealant cures when exposed to room temperature immediately. An RTV sealant is highly preferred because its adhesive, holds its shape, and is a water repellent. Unlike natural rubbers that get easily deformed and are sticky, RTV sealants are very stable. RTV is available in textures ranging from 15 shores to 40 shores. It can stick two surfaces together while it provides a cushion at the same time.

Application & Types of RTV Sealant

RTV Gasket

A gasket helps to prevent leakage when it’s used to join two objects. RTV sealant is mostly used as a gasket compound. RTV forms a tough and flexible rubber once exposed to room temperature. This helps it to resist aging, weathering, and extreme temperatures without cracking or hardening. Common characteristics of RTV sealant include high-temperature resistance, ease to dismantle, high flexibility, oil resistance, and universal seal. RTV gasket can be used to fix doors of high-temperature equipment such as oven doors or fit heavy-duty applications such as towing, and other automobile uses.


One of the most critical components in any gearbox system is the shaft seal. This easily underestimated gearbox component is essential for long-term leak-free operation. RTV sealant does not contain harmful strong orders, and it features a light adhesive characteristic. Fast-drying can be achieved in 15 minutes. It is the first choice for gear sealing.

In addition to the above two applications, RTV silicone rubber also has a wide range of applications and can be used to seal a variety of components, including value covers, oil pans, transmission pans and water pumps. In industrial applications, RTV sealant can replace various rubber pads, asbestos pads, cork pads and paper pads.
