BRB Silicones showcases BRB SF 1802 at SEPAWA 2023
19 September 2023

BRB SF 1802 is a low viscosity amino alkyl functional polydimethylsiloxane. It is a curable and non-reactive amino silicone which, compared to its reactive counterparts, exhibits increased storage stability. BRB SF 1802 is designed for use in Car Care applications; however, it can also be used in Home Care formulations.

In Car Care application, BRB SF 1802 is used in paint protection formulations to provide hydrophobicity, high gloss and good durability. BRB SF 1802 can be also combined with reactive silicones to formulate glass sealants. Due to its low viscosity and low surface tension, BRB SF 1802 is very easy to apply and wipes off effortlessly, without smearing.

When compared to standard silicone oils, BRB SF 1802 exhibits an excellent affinity to various substrates. This characteristic is the main reason of the increased durability of amino silicone-based coatings. As BRB SF 1802 leaves the treated surface very smooth, it makes it difficult for dirt to stick to it and a simple pressured rinse with water is usually sufficient to remove most of the contaminants.
