We use the same great RTV silicone that is sold under well known brands for twice the price. 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. It can be used as an adhesive for bonding surfaces together. It is the #1 choice by manufacturers for the assembly of their products when there is no margin for error. It is superior for all types of sealing, bonding and makes a tough and durable adhesive.

Our Project 1 Silicone Sealants do a wonderful job on 99% of all applications but when you have an application that requires superior adhesion and all around extended performance you need our Premium Industrial 100% RTV Silicone Adhesive/Sealant.

Use as a direct replacement for:
Dap 08641, Dow Corning 732, GE 100 Series and more.

TT-S00230C (COM-NBS) Class A MIL-A-46106B Amend. 3, Type 1. Canadian 19-GP-9MA Type 1. Meets ASTM C920, Class 25.

11100 Series Premium Industrial Silicone is supplied in a 10.1oz (300ml) caulking cartridge, 5 gallon pails, and 55 gallon drums.

Warranty and Shelf Life:
Each application should be pre-tested for suitability of this product for the intended use. When stored in the original, unopened container at temperatures less than 90 degrees F (32 degrees C), our Silicones are guaranteed for one year from date of purchase.


Important user note: Although this is our Premium Silicone Sealant it has an acetoxy curing system and will not adhere well and is not recommended for use on vinyl windows, vinyl doors, vinyl siding, vinyl or coated guttering applications, concrete, stone, brick or most masonry work. You will need our Project 1 Neutral Cure Silicone Sealant or one of our Polyurethane sealants for those tough jobs.

Important note: Paint will not adhere to silicone sealant but silicone sealant will adhere to most painted surfaces. Always paint first and then seal. Make sure the paint has had time to dry completely before applying silicone sealant.
