Silyl-Modified Polymers (SMP)

Silyl-modified polymers (SMPs) are silane-terminated polymers that contain silyl group (-SiR₃) in their chemical structure, where Silicon [Si] atom bonded to an organic group [alkyl or aryl] represented as R. These polymers are known for their versatile properties to provide for good bonding strength, durability and elasticity to accommodate applications in various industries. 

The range of products offered as SMP adhesives in our selection guide is solvent and isocyanate-free, without the need to add cleaners or primers during the preparation. Since they can withstand a wide range of temperature and humidity ratios, SMPs can be a great application for industries with high dynamic usage such as EV battery manufacturing.
These moisture cure adhesives can perform under harsh conditions on several substrates and are suitable for EV battery Cell assembly to provide a firm and durable waterproof seal that resists all kinds of vibration and shocks of the EV vehicle.

SMP Properties

Silyl-modified polymers (SMPs) excel in the fields of adhesives and sealants, showcasing their impressive ability to establish strong bonds. These versatile polymers create reliable connections with various surfaces, ensuring durability across a wide range of applications. Whether applied in industrial settings or everyday consumer products, SMPs stand out for their capacity to form adhesive bonds that withstand challenges in diverse environments. 

The inherent flexibility of Silyl-modified polymers introduces a dynamic quality to their applications. These polymers exhibit a level of flexibility particularly beneficial in scenarios involving constant movement or changing substrate conditions. This flexibility guarantees that SMP-based adhesives and sealants maintain their effectiveness, even in situations where rigidity could compromise performance.

The crosslinked network formed by the silyl groups in SMPs imparts impressive weather resistance. This characteristic makes SMP-based sealants and adhesives well-suited for outdoor applications where exposure to harsh environmental elements is a concern. The robust crosslinking not only enhances the durability of SMPs but also shields bonded surfaces from the detrimental effects of sunlight, moisture, and temperature fluctuations. As a result, SMPs contribute to the long-lasting and dependable performance of products intended for outdoor use, spanning from construction materials to automotive applications.

Polyurethane (PU)

Polyurethane (PU) adhesives derive their characteristics from the chemical group urethane present in the formulated or cured product. PUs exhibit a broad range of curing rates, processing flexibility, and mechanical properties, owing to the versatile nature of PU chemistry. Notably, they offer exceptional adhesion to substrates containing hydroxyl groups, such as wood, wood-derived materials, brickwork, concrete, certain plastics, and paints. However, substrates like glass, aluminum, and alkaline surfaces may require primers for optimal bonding, promoting adhesion while shielding the adhesive from negative substrate interactions.

Polyurethane (PU) Properties

One part PU adhesives have largely replaced 2-part polysulfide adhesives in the construction industry due to their ease of use and cost-effectiveness. PU adhesives typically offer continuous temperature resistance up to 90°C (194°F), suitable for diverse industrial, commercial, and residential applications. While some grades may experience color change and brittleness when exposed to prolonged UV light, certain formulations overcome this limitation. In their fully cured state, PU adhesives exhibit high resistance to water and aqueous salt solutions, even at elevated temperatures, but may be permanently damaged by strong bases and acids. The solvent content in many PU adhesives enhances flow characteristics, but a relatively high content (up to 15%) can lead to pronounced shrinkage during curing, potentially distorting final assemblies and internal stresses.

PU adhesives are well-suited for coating with 1C or 2C varnishes and paints containing solvents. Many 1C paints, also based on PU chemistry, are highly compatible with PU adhesives. The wet-on-wet method allows direct application of paint over uncured PU sealant, enabling simultaneous curing. However, 2C paints, highly resistant to moisture diffusion, can potentially slow the sealant's curing process. Unlike many other sealing systems, PU adhesives can be painted when fully cured, offering advantages in terms of paintability and cost-effectiveness for the transport industry, vehicle manufacturers, and repair shops.

In cases where the cure speed of 1C PU adhesives is inadequate, 2C products can be used. The base resin and isocyanate hardener are supplied separately, requiring thorough mixing for a homogeneous curing sealant. These properties make PU adhesives versatile and well-suited for various applications, including the automotive industry, where they play a critical role in safety and vehicle functionality.

Curing Process

The cure mechanism of a 1 part adhesive relies on atmospheric moisture to initiate the hydrolysis and condensation process. Curing commences upon exposure of the uncured polymer to atmospheric moisture, initially forming a skin on the surface before gradually progressing inward. The cure rate is directly influenced by environmental relative humidity and temperature. It's noteworthy that adhesive strength may continue to evolve for one to two weeks post-application, attributed to the 'outside–in' curing process. Faster cure speeds can be attained by introducing additional moisture and elevating the temperature.

1-Component curing process

  • Step 1: After dispensing, the adhesive undergoes exposure to atmospheric moisture.
  • Step 2: Moisture permeates the uncured adhesive, progressing from the external to the internal layers.
  • Step 3: Hydrolysis is initiated by moisture contact, followed by condensation.
  • Step 4: Alcohol is released as a by-product during condensation.
  • Step 5: Crosslinking initiates promptly following condensation.


A 2-part adhesive employs a moisture-curing mechanism similar to that of a 1-part adhesive; however, in contrast to Single-part systems, Dual systems undergo curing independently of atmospheric moisture. This distinction results in 2C systems consistently showcasing faster curing rates than their 1C counterparts, accompanied by a more extensive depth of cure. Adhesives demonstrate inherent stability both in the presence of moisture without catalysts and with catalysts in the absence of moisture. Yet, when catalyzed systems come into contact with moisture, they swiftly initiate the gelling process through hydrolysis, subsequently progressing into a condensation cure.

2-component curing process

  • Step 1: Combine Components A and B before applying the adhesive.
  • Step 2: Initiate hydrolysis and condensation within the system.
  • Step 3: Release alcohol as a by-product during condensation.
  • Step 4: Commence crosslinking immediately after condensation.
