Bismaleimide triazine (BT) resin is a high-performance resin based on bismaleimide (BMI) and cyanate (CE) with very good thermal stability, moisture resistance, low dielectric constant, and low dielectric loss properties. It is one of many thermoset resins used in printed circuit boards (PCBs) and is often used as a substrate for the chips used in PCB mobile phones.
In a wide range of applications, BT substrates with functional surfaces can provide numerous performance advantages. Alfa Chemistry provides BT substrates with unique functionalized surface coating services. With our wide and straightforward surface modification procedures, you can change the surface attributes of practically any BT material-related product. Working with us gives you the assurance that you'll be able to change the surface of your product with ease!
Alfa Chemistry provides a comprehensive range of polymer surface coating methods to its customers, which may be used to functionalize the surface of BT materials of all types in order to improve their varied surface qualities. The following are some of our surface modification technology possibilities, however, they are not exhaustive. Please contact us for more technical information.
All of these nanoscale coatings are chemically stable, optically transparent, and extremely long-lasting.
Case 1: Fire-Resistant Nanocoating
Alfa Chemistry has created an ultra-efficient fire-resistant nanocoating based on carboxymethyl chitosan (CCS) and modified montmorillonite, which was inspired by pearl layers (MMT). The nanocoatings have well-aligned pearl-layered layered microstructures, which display high transparency and a distinct pearl-layered iridescence. By dip coating or spraying the nanocoatings onto multiple huge polymer substrates, they provide super-efficient fire safety. All coated substrates were self-extinguishing in combustion tests. Their heat and smoke emissions were also greatly lowered at the same time. Furthermore, they contain no organic solvents, halogens, or phosphorus, making them environmentally friendly.
