MMAs
Methyl Methacrylate Adhesives
Strong, reliable, and versatile structural bonding. SAF & FIT adhesives deliver proven MMA performance—with immediate availability across Canada.
The SAF & FIT Advantage
Engineered with patented methacrylate technology, Bostik’s SAF & FIT adhesives combine strength, flexibility, and durability in a single solution. They bond metals, plastics, and composites with confidence—delivering long-lasting performance in demanding industrial applications.
Build for Demanding Projects
- Exceptional flexibility (up to 400% elongation)
- High durability with resistance to chemicals and fatigue
- Fast curing—open times from 1 to 90 minutes
- Reliable bonding across dissimilar materials
Key Benefits at a Glance
Wide Service Temperature range
Usage between -40°C to 150°C, while keeping mechanical properties.
Non-sag, application on vertical surface
Remains in position when applied on vertical or overhead surfaces
Permanent toughness and high elongation
Very high elongation and impact resistance even after ageing
Wide range of open and curing time
Selection to fit application and process requirements
What are the differences between SAF & FIT and Standard Methyl Methacrylate Adhesives?
High Flow & Thixotropy
Formulated with high thixotropic properties, SAF and FIT range offer no sagging, excellent shaping, and less quantity used for gap filling.
This combination of High Flow and Thixotropic benefits improves:
- Workability
- Process efficiency
- Cost-in-use
Impact Resistance
This video shows the differences between SAF and FIT MMA and Standard MMA through impact resistance lab test.
Strong impact resistance improves:
- Durability
- Aesthetics
- Safety
Elongation & Flexibility
SAF ranges have exceptional elongation properties more than 8 times higher than standard MMA while keeping high bonding strength. Through flexibility test, SAF & FIT demonstrate high flexibility that helps to avoid read-through and absorb differential expansion/contraction of the substrates.
This combination of elongation and flexibility benefits improves:
- Aesthetics
- Process efficiency
- Durability
Visual Monitoring of the Reactivity
SAF & FIT enables fast and visual mixing control with black hardener, and polymerization mixing control with white hardener. They also offer short handling time while having a long open time.
Reactivity property improves:
- Workability
- Higher Production speed
- Cost-in-use
Advantages of MMA Structural Adhesives Compared to Other Technologies
Mechanical Fasteners
- Greater durability—MMAs spread stress evenly, unlike fasteners
- Less labour—intensive (increased productivity)
- Lower weight
- Corrosion-free
- Gap filling
- Better aesthetics
Welding
- Lower cost—no post-finishing required
- Versatile bonding—works with dissimilar materials and reduces labour
- Corrosion-free
- Lower weight
- Gap filling
- Better aesthetics
Polyurethanes
- High bond strength and good impact resistance
- Large gap fills, less sensitive to the environment
- Good chemical and environmental resistance
- Fast cure speed
- Minimal health risks (non-isocyanate)
