Coating industry trends has driven increased use and interest to develop more efficient and durable thermal insulative coatings. The key areas for this expansion are to reduce corrosion under insulation, increase occupational safety and reduce energy loss. Key features of these water-based coatings are low thermal conductivity, high hydrophobicity and adhesion along with an emerging interest to have greater heat resistance and stability. This paper will introduce a new water-based silicone hybrid resin to accompany the two novel microporous composite granules; one with high thermal insulative efficiency and the other, a pure hydrophobic synthetic silica pearl shaped filler to optimize thermal insulation efficiency as well as offering mechanical stability and reduced cracking in these highly filled coatings. The new platform offers the formulator options to leverage all new technologies together or separately when a compatible binder is needed to increase thermal heat stability and flame-retardant performance. Coatings and formulating details will be highlighted with thermal degradation of binders, surface temperature comparison for “Safe Touch” coatings, thermal conductivity (Lambda - mW/mK), contact angle measurements along with fire retardance test and direct flame testing using various thermal insulation fillers.

Novel Composite Overlay for High Temperature Corrosive/Wear Applications

Product Number: 51324-20925-SG

Author: Gary Fisher

Publication Date: 2024

Synergistic erosion and corrosion at elevated temperatures is a prevalent condition in oil refining and power generation. Corrosion resistant alloys do not tend to be durable under wear conditions, whilst common wear-resistant solutions such as tungsten carbide-based coatings display poor resistance to oxidation and corrosion. This work details the development of a composite overlay, deposited by plasma transferred arc welding, that has been designed to exhibit high levels of wear protection coupled with resistance to oxidizing and carburizing environments. The performance of the composite is provided by the corrosion resistance of a MCrAlX-type alloy, which acts as a matrix for a homogenous distribution of chromium-based carbides. The protective oxide promoted by the matrix alloy, combined with a dense population of in-situ formed primary carbides act synergistically to provide resistance to high temperature corrosive/wear environments. The presentation details the alloy selection and development of the deposition process. The performance of the composite is assessed under abrasive wear, oxidizing and carburizing conditions, and gauged against commonly used corrosion resistant alloys.
