Bis-A Resins
High Chemical & Thermal Resistance.
When standard polyester resins aren’t enough, our Bisphenol-A (Bis-A) modified resins provide exceptional durability, chemical resistance, and thermal performance for the most demanding environments.
For the Harshest Environments
Bis-A resins are specialty unsaturated polyester resins modified with Bisphenol-A (bis-A). This molecular backbone provides enhanced resistance to corrosive chemicals, heat, and solvents, while retaining the versatility of UPR processing.
They are the go-to choice for chemical processing equipment, industrial applications, and structural composites where exposure to harsh environments is inevitable.
At Happy Composites, we deliver ISO 9001:2015 certified Bis-A resins to U.S. buyers with full compliance and logistics, ensuring you get performance and peace of mind.
