Professional Bonding: Switching from PU Adhesive to MS Polymer

With ACROBOND MS 38, ACROM offers a reliable alternative to traditional polyurethane (PU) adhesives, without compromising on performance.

While PU adhesives are recognised for their mechanical holding power, they present several constraints: long setting times, emission of harmful compounds, and safety training requirements for the use of diisocyanates. Conversely, MS Polymer adhesives like ACROBOND MS 38 offer cleaner application, faster polymerisation, and improved safety for the user.

Designed for professionals in construction and industry, this product allows for the replacement of two PU references with a single solution that is simpler to store, apply, and handle on a daily basis.

REACH Regulation: Changes for Polyurethane Adhesives

Since 24 August 2023, the use of products containing more than 0.1% of diisocyanates—such as polyurethane adhesives—has been restricted by REACH regulation. This restriction now imposes mandatory training for all professionals required to handle these substances.

Objective: To reduce health risks, particularly allergies and respiratory conditions caused by toxic vapours during application.

This new regulatory framework increases internal procedures, complicates procurement, and extends lead times on construction sites or in production.

ACROM anticipated this development by developing ACROBOND MS 38, which can be used without prior training. Simpler to implement and compliant with current standards, it offers a concrete response to safety and compliance requirements in the building, industry, and transport sectors.

Technology Optimised for Field Use

ACROBOND MS 38 does not merely replace PU 30 and PU 38 adhesives: it surpasses them on several key points.
 

Thanks to rapid skin formation (15 to 20 minutes compared to 40 to 45 min for a classic PU), immobilisation time is reduced, which accelerates production rates. Its high thixotropy allows for clean application, without sagging, even on vertical joints or ceilings. The formulation, free from shrinkage and bubbles, ensures a regular finish, a mark of quality in visible assemblies.

Resistant up to +100°C, it is suitable for both structural applications and demanding environments. It is paintable, just like PU adhesives. Finally, its elongation at break is adapted to moderate deformations, making it a reliable adhesive sealant for a wide range of uses in industry, finishing works, and construction.

In summary:

• Fast skin formation: 15 to 20 minutes versus 40 to 45 min for PUs.
• Clean and precise application: Thanks to high thixotropy.
• Formulation without shrinkage or bubbles: For a quality finish.
• Thermal resistance: Up to +100°C.
• Paintable: Just like PU products.
• Mechanical resistance: Adapted to the majority of industrial and construction uses.

A Compliant, All-in-One Solution

Adopting ACROBOND MS 38 means freeing yourself from the regulatory constraints imposed on polyurethane adhesives.

Formulated without isocyanates, this adhesive sealant requires no REACH training. This is an advantage for companies wishing to reduce administrative procedures, limit production interruptions, and protect the health of their applicators.

PU adhesives, despite their performance, present a significant constraint: the risk of causing skin and respiratory problems. By replacing them with an MS Polymer like ACROBOND MS 38, exposure to sensitising substances is eliminated, while maintaining a high level of performance.

Another field advantage: a single reference replaces two products (PU 30 and PU 38), which simplifies stock, orders, and application habits. A simpler, safer, more rational solution.

Health, Regulation: Towards a More Responsible Industry

Polyurethane adhesives have long been favoured for their strength and versatility. But their use now raises questions: presence of diisocyanates, restrictive labelling, mandatory REACH training... Not to mention the risks to the health of applicators, exposed to irritating vapours and long-term effects.

Faced with these challenges, MS Polymer adhesives—like ACROBOND MS 38—offer a safer and compliant alternative. They limit risks, simplify implementation, and align with a responsible approach.

The purchase cost is higher for an MS Polymer adhesive, but they allow for a reduction in hidden costs: training, protective equipment, risk management, site shutdowns. ACROM chooses sustainable chemistry, without compromising on performance.

To change is to anticipate. Choosing our ACROBOND MS 38 adhesive means participating in a greener industry that respects both users and their environment.
