- New product.
No applicator.
EXPIRATION DATE 06/2025
Sikaflex®-554 is a flexible, one-component STP (silane terminated polymer) adhesive system, specially developed for bonding large components in industrial assembly.
It has good adhesion to a wide range of substrates with minimal pre-treatment. Sikaflex®-554 can be accelerated using Sika Booster technology and the PowerCure system.
ADVANTAGES
- ▪ Good adhesion to various types of substrates without the need to use a primer
- ▪ Very good resistance to atmospheric factors
- ▪ Compliant with DIN EN 45545-2 R1/R7 HL3
- ▪ Fast curing thanks to Sika Booster technology or PowerCure system
- ▪ Solvent, isocyanate, phthalate and PVC free
- ▪ Withstands dynamic loads
AREAS OF APPLICATION
Sikaflex®-554 is suitable for joints that will be subjected to dynamic loads.
Suitable substrate materials include metals, especially aluminium, metal backings, paints, steel sheet, ceramics and some plastics. Good adhesion to a wide range of substrates with minimal pre-treatment. Before using Sikaflex®-554 on materials susceptible to stress cracking, tests should be carried out on the original substrates.
Sikaflex®-554 is intended for professional use, adhesion and material compatibility tests with the current substrates and conditions should be carried out before application.
TREATMENT MECHANISM
Sikaflex®-554 cures by exposure to atmospheric moisture. If the ambient temperature is low, the water content in the air is also low, which slows down the curing reaction.
CHEMICAL RESISTANCE
Sikaflex®-554 is generally resistant to fresh water, sea water, diluted acids and diluted caustic solutions; temporarily resistant to fuels, mineral oils, vegetable and animal fats and oils.
Sikaflex®-554 is not resistant to organic acids, glycolic alcohol, concentrated mineral acids, caustic solutions and solvents.
