1. Product Overview & Specifications

PACM (1,3-Bis(aminomethyl)cyclohexane) (CAS 1761-71-3) is a cycloaliphatic diamine epoxy curing agent with exceptional thermal stability and chemical resistance. Key parameters:

2. Applications & Use Cases

Primary Industries:

• Composite Materials: Aerospace/automotive structural parts requiring high Tg (180-220°C).
• Electronic Encapsulation: LED potting, semiconductor underfills (CTE < 60 ppm/°C).
• Adhesives: High-strength bonding for metals/plastics (lap shear strength >20 MPa).
• Coatings: Chemical-resistant tank linings (withstands pH 1-14).

4. Real-World Customer Case Studies

Case 1: Aerospace Composite Manufacturer

Client: AeroTech Solutions (France)
Challenge: Needed HDT >200°C for engine cowlings.
Solution: PACM-based system cured at 150°C/2h + 180°C/4h.
Result: Achieved Tg 215°C, 40% weight reduction vs aluminum.

Case 2: PCB Encapsulation Provider

Client: Shenzhen ElectroGuard Co. (China)
Challenge: Delamination in high-humidity environments.
Solution: PACM formulation with 0.5% silane additive.
Result: 0% failure after 1000h 85°C/85% RH testing.

5. Usage Guidelines

Mixing Ratio: 25-35 PHR (per hundred resin)
Cure Schedule:
