Construction Sealant Advancements

As cited in ASI Magazine, recent construction growth is fueling sealant demand. This is due in large part to the following:

  • Infrastructure improvements in developing countries
  • Increasing urbanization

Yet construction sealants themselves are also at the forefront in terms of development and advancements. This is further fueling their market segment’s growth.

Let’s take a closer look at some of these specific developments and advancements in recent years. get modafinil prescription uk https://www.methanol.org/

Improved Weatherability

A construction sealant’s weatherability is defined by its degree of resistance when exposed to elements such as:

  • Heat
  • Cold
  • Solar radiation
  • Moisture

In recent years, formulators have faced pressures to ensure construction sealants have weatherability for 20+ years. To meet these demands, they have started developing new products and reliable test methods to evaluate formulas and test for service life.

In order to develop these new, high weatherability construction sealants, formulators have re-examined the following influencers:

  • Raw material composition
  • Polymer chemistry
  • Titanium dioxide
  • Plasticizers
  • Stabilizers

Doing so has helped them manufacture new construction sealants with improved weatherability.

Increased Sustainability

In response to government and societal pressures, construction sealant formulators have made sustainability improvements to products in recent years as well. For example, sealants now contain little to no volatile organic compounds (VOCs) and have virtually no  odor.

VOC reduction in construction sealants has been made possible due to certain advancements in the chemical industry. These have included:

  • Changes to existing formulations: Some types of formulations have been in existence for several decades. Now, manufacturers are able to revisit the formulation and reduce the amount of solvents used within it, which contribute to VOCs.
  • New hybrid formulations: These new formulations allow for high performance without the use of solvents.

Improved Adhesion

Formulators have also focused on improving construction sealant adhesion in recent years. This has stemmed in large part from the following factors:

  • End-users want a better product with increased adhesion and over a longer life cycle.
  • Increased competition
  • New regulations

As a result, manufacturers have made changes in sealant formulation that improves adhesion to traditional building materials. These include:

  • Masonry surfaces
  • Brick
  • Most woods
  • Metals such as anodized aluminum, galvanized metals and steel

They have also designed construction sealants that offer adhesion to more difficult to bond building materials, such as Kynar® resin-based coatings and PVC boards. Formulators have also overcome challenges to improve adhesion even when reducing solvents.
