What does RTV stand for in silicone?
RTV is a type of liquid silicone rubber that vulcanizes at room temperature and is heat resistant up to 180°C. Room Temperature Vulcanizing means that the silicone solidifies at room temperature. There are two types of room temperature vulcanizing silicones: RTV-1 is a ready-to-use, one-component silicone.
The key difference between RTV and silicone is that RTV is a general term for room temperature vulcanizing silicone, whereas silicone is a polymer material having repeating units of siloxane. When considering the chemical structure, RTV silicone has crosslinks while normal silicone may or may not have cross-links.
RTV silicone (room-temperature-vulcanizing silicone) is a type of silicone rubber that cures at room temperature. It is available as a one-component product, or mixed from two-components (a base and curative).
Chemical structure
RTV-1 silicones are made of a mixture of polydimethylsiloxanes, crosslinking agents (creating 3-dimensional network), fillers, and auxiliaries. Crosslinking is triggered when the material comes into contact with atmospheric moisture and then proceeds to eliminate unwanted byproducts.
Return-to-vendor or RTV is a label that is given to products that are sent back by a customer or retailer, either to be returned for a refund or replacement, or to be repaired.

RTV Silicone Gasket can be used to replace most cut gaskets or any dressing. It's typically applied in sealing panels, window plates or on high-temperature equipment like oven doors.
Performance Of 100% RTV vs.
Pure silicone will have stronger adhesion, less shrinkage lower temperature application, and stronger resistance to weathering. If you are using your silicone in an oven or on a rooftop in Florida, 100% RTV will handle the heat much better.
Job Description. Checks damaged, deleted, and defective goods to Return-to-Vendor inventory in the computer. Obtains vendor return authorization for items and ships out.
RTV Silicones have a 40-year life span and a high degree of elongation; they are easy to dispense, even in cold temperatures, and are VOC compliant, with excellent UV and thermal stability properties.
What are the three types of silicones?
The various types of silicone rubbers include room temperature vulcanize, liquid silicone, fluorosilicone and high-consistency rubber.
Generally, silicone RTV mold making rubber does not stick to anything, and nothing will stick to it. The exception is that it will stick to itself, other silicones, silica, and glass.
Each type of RTV silicone, while fairly interchangeable, has its own characteristics that may make one better than another depending on the application. All RTVs can be used for the most common uses – valve covers, timing covers, oil pans, essentially the basic surfaces that need to keep the fluid in and the dirt out.
TYPICAL CURING PERFORMANCE
Permatex® Optimum Red RTV Silicone Gasket cures on exposure to moisture in the air. The product dries tack free in one hour and fully cures in 24 hours. Cure times will vary with temperature, humidity and gap.
Room temperature vulcanization (RTV) molding, often referred to as resin casting or silicon molding, is an affordable solution for prototyping, functional testing, product demonstrations and short–run production.
Managing Vendor Returns. This chapter provides an overview of the return to vendor (RTV) business process and discusses how to: Set up RTV processing options.
Momentive is part of a legacy that was first to make silicone adhesives available commercially, and it continues today to expand its diverse line of room temperature vulcanization (RTV) silicones, silicone-based pressure sensitive adhesives (PSAs) and adhesive formulations used in electronics applications.
What Is Return to Vendor? An established process, return to vendor refers to when a user or retailer arranges the return of goods to a vendor. A user, for instance, may initiate a return, sending the product to the retailer where they purchased it. The retailer then forwards the product back to the vendor.
11100 SERIES-PREMIUM 100% RTV Silicone Sealant is a high quality, single-component, 100% silicone sealant that is perfect for interior and exterior sealing and caulking. It adheres to metal, glass, marble, tile, ceramic, porcelain, painted surfaces, non-oily woods, and rubber.

What should RTV not be used on?
Please note that RTV is not to be used on the entire gasket; the gasket should be installed clean and dry. RTV should only be used on the corners of the gasket and/or stepped casting areas that have a gap.
"room temperature vulcanization" with good performance, excellent adhesion and flexibiliy with high modulus and good tensile strength. Fully waterproof, with a long lasting and powerful caulking formula which provides a tight weather-resistant elastic seal for glass, metal and ceramic surfaces.
RTV stands for room temperature vulcanizing. RTV silicone begins to cure immediately upon being exposed to air, as opposed to the curing agents in water-based sealants (for example, latex).
Unless a primer is required, you should apply the sealant to the prepared surface. Apply an even coat to all sides of the gasket.
Black RTV can flex, allowing it to retain its bonds between two different material types that will heat and cool at different speeds. Grey RTV has higher density when cured for higher vibration resistance and tight tolerance applications. Red RTV is for exhaust and high heat applications.
