Dow have announced three grades of Betamate structural adhesives have passed the European Standard EN45545-2 for railway vehicles.
Betamate 2700 A/B, Betamate 7120-1F and Betamate 7170 were tested and satisfied the hazard level (HL) requirements for EN45545-2.
Tests included applying the adhesives in conjunction with steel, testing for window assemblies, interior and exterior surfaces, floor structures and other general interior and exterior bonding applications.
The three Betamate adhesives are suitable for railway vehicle manufacturing where applications range from bonding windows and surfaces inside and outside, bonding trim components, floor panels and coverings as well as general applications.
Betamate 2700 A/B
- High viscosity
- Rapid curing; cures independently of moisture
- Very good, non-sagging
BETAMATE 2700 meets the hazard level requirements for R22 and R23 (interior and exterior sealing).
- High strength, permanently flexible adhesive joints
- Medium viscosity, low modulus adhesive
- Excellent UV stability
- Generous working time
BETAMATE 7120-1F meets all three HL requirements for R1 and R7 (interior and exterior applications) and for R10, R22 and R23.
Betamate 7170 Quick Fix
One component, polyurethane structural adhesive and sealant
- Quick fix (warm applied)
- High viscosity
- High Strength
- Permanent elastic adhesive joints with accelerated hardening
- Excellent paint adhesion
- Low conduction
BETAMATE 7170 satisfies the requirements of all three hazard levels for R1, R7 and R10 for structural bonding including R22 and R23 for interior and exterior sealing.
