NEW Two-part high performance acrylic adhesives: also suitable for galvanized surfaces Enhance productivity and performance Next generation two-part structural acrylic adhesives Low odour.

Faster.

Stronger.

Longer shelf-life without refrigeration.

Manufacturers around the world rely on acrylic adhesives to design and produce new products – and with good reason: acrylic adhesives bond well both to plastics and metals and achieve high structural strengths faster, often on oily or contaminated surfaces.
When developing a new generation of two-part acrylic adhesives, 3M researchers focused on solutions for a variety of challenges.

Faster cure DP 8805 NS reaches an overlap shear strength of 6.9 MPa in less than nine minutes – which is twice as fast as conventional acrylic adhesives.

Rate of strength build for structural adhesives Aluminum overlap shear bond; room temperature Higher impact resistance DP 8405 NS has over three times the impact strength of conventional acrylic adhesives.
This makes it ideal for many industrial applications, helping build stronger products for challenging applications.

Four of the adhesives feature a new low odour formulation to enhance work comfort even more.

18-month shelf life without refrigeration 3M’s new two-part structural acrylic adhesives do not require refrigeration, making them much easier to store.

They also have an 18-month shelf life.


3M™ Scotch-Weld™ two-part structural adhesives for use in EPX System On the fast track to bonding: two-part acrylic adhesives stand the burn-in test 3M’s next generation two-part acrylics feature defined open times, fast cure, almost odourless formulation and extreme heat resistance.
This qualifies them particularly well for use in metal structures that have to be bonded before powder coating – a common practice and a decisive factor for fast, reliable and above all cost efficient bonding in vehicle, machinery and plant engineering.

The tough and durable DP 8405 NS as well as the low-odour DP 8805 NS and DP 8810 NS have been subjected to burn-in tests on aluminum and rolling steel.

3M’s laboratory tests simulated the typical powder coating line with a cycle time of approx.
30 minutes at 200°C as well as cathodic dip coating with similar exposition values.

Tests were carried out on P2 etched aluminum and oiled rolling steel – that is on substrates which are commonly used in finishing processes.

After curing times of 30 minutes, as well as after two and four hours at 23°C, the adhesive joints were exposed to high temperatures.

The results showed that the strength of the adhesives remains high, even when exposed to heat and high loads.
Thus the temperature range of 40°C to 100°C is absolutely no problem for long-term stable adhesion – the tested products even withstand temperatures of up to 200°C with tensile shear strengths of between 1.6 MPa and 1.8 MPa.

3M™ Scotch-Weld™ two-part structural adhesives for use in EPX System Two-part acrylic adhesives in use: faster processing – better products Shortening cycle times in the manufacturing process and improving product quality – these are challenges faced by many companies.
Two-part acrylic adhesives are increasingly becoming the first choice when implementing new projects in numerous markets and applications.

The new generation of acrylic adhesives has been winning over customers across the board since 2014.

Now 3M is expanding this range.

Adhesives expert Antonio Pagliuca provides information about the new products.

Dr Pagliuca, why is 3M expanding its range of two-part acrylic adhesives by three new products?

New to our range is a specialist product suitable for metal surfaces and two products with extended curing times.
With these variations we are responding to feedback from the market, giving our customers an even better possibility to choose the best product for their applications.

At the same time, the proven advantages – low odour and high temperature resistance – remain unchanged.

Metal as high-surface energy materials are easier to bond than many plastics.

What is so special about the new two-part high-performance acrylic adhesives?

DP 8407 NS has been especially optimized as an adhesive for metals.
The product is oil tolerant, elastic and contains a corrosion inhibitor.

DP 8407 NS is therefore suitable not only for use on coated metals and unalloyed steels but also for bonding galvanized surfaces.

Bonding these materials with conventional may cause corrosion and adhesion issues.

Which users do you primarily want to appeal to with this product?

The topic of lightweight construction plays a major role throughout the metalworking industry.
DP 8407 NS is interesting here as this high-performance acrylic adhesive enables fast and efficient bonding of metal to metal – and also of metals to other materials.

Conventional, non-lightweight construction compatible bonding processes such as welding or riveting can be perfectly replaced by using adhesives.
