Epoxy resinEPOLEAD PB4700
EPOLEAD EPOLEAD PB4700 Epoxidized polybutadiene
EPOLEAD PB series is an epoxidized polybutadiene that gives a coating film with rubber elasticity by using various curing agents such as phenol resin, acid anhydrides, polyamines, and cationic catalysts.
EPOLEAD PB series, which has a lower epoxy equivalent than conventional epoxidized polybutadienes, is characterized by its excellent compatibility with bisphenol A glycidyl ether type and cresol novolac type epoxy resins, and it can impart rubber elasticity to the coating.
EPOLEAD PB4700 is characterized by its lower viscosity and lower epoxy equivalent compared to EPOLEAD PB3600.
Characteristics
- Excellent properties of cured products (rubber elasticity, transparency, shock resistance, flex resistance)
- Excellent in compatibility with epoxy resins
- Low epoxy equivalent (Compared to conventional products)
Applications
- Materials for cationic curing resin (clear coating, ink, adhesive, stereolithography)
- Can coating (phenol resin curing)
- Cation electrodeposition paint, water-based paint (amine curing)
- Semiconductor sealing material (acid anhydride curing)
- Printed circuit board material
