Chemicals, Company News

ReAgent is an industry-leading chemical manufacturer with the experience and skill set to create bespoke chemical coatings for a range of businesses worldwide. There many different types of chemical coatings that can be manufactured, and today we’re looking at the top 5.

A chemical coating is any formulation that is applied to a material in order to change or enhance certain properties, whether it’s water repellency, flame retardancy or durability. They can also be applied to a huge range of surfaces, including fabric, steel, glass and wood.

Different Types of Chemical Coatings

Chemical coatings can be used in a huge range of applications to reduce costs, increase efficiency gains and improve the performance of a product. At ReAgent, we’re lucky to be involved in the manufacture and distribution of a variety of different chemical coatings.

  1. Fabric Coatings for Revolutionary Airbags

Chemical coatings are used on fabrics to achieve many different characteristics. Coated fabrics are used in a huge range of industries, including aerospace, geotextile and HVAC applications. At ReAgent, we manufacture chemical coatings for the automotive industry.

ReAgent manufactures the fabric coatings for one of the biggest market leaders in automotive safety. This blue chip automotive company supplies specialist airbags that save up to 25,000 lives every year.

The airbags are made by weaving together raw materials before coating the product with a bespoke chemical blend that replaces the traditional silicone-based airbag coatings. There are several benefits to this kind of fabric coating:

  • It keeps all the gases inside the airbag
  • This keeps the airbag inflated for longer
  • It is of a lower coat weight than silicone
  • It is water-based, making it more user-friendly

ReAgent is involved in the manufacture of this bespoke chemical coating, producing up to 1,680 tonnes per year. Our 40+ years of experience and quality-approved manufacturing processes all ensure that these chemical coatings meet the stringent standards and safety requirements of our client.

  1. Polyurethane Coatings

There are many chemical coatings that use polyurethane. A high-resistance, flexible compound that can be used in a variety of industries, polyurethane is a polymer comprised of organic units and carbamate links. Polyurethane is also very resilient, can be applied to many different substrates and can be altered to achieve desired characteristics, e.g. hydrophobicity

ReAgent works with a chemical giant to help repack their polyurethane resin bound system known as Elastopave®. This innovative formulation is mixed with aggregate to create a unique paving solution that can be used on car parks, pool sides, stone carpets and even factory floors.

Elastopave® is slowly revolutionising infrastructure all around the world by:

  • Providing a highly durable alternative to tarmac or asphalt
  • Being light-fast and UV stable so that it won’t degrade over time
  • Being manufactured to a 1K polymer system instead of a 2K one
  • Being water-permeable, allowing water to migrate through it instead of gather on top of it

When used in chemical coatings or resin bound systems, polyurethane formulations provide many advantages in the form of product longevity, efficiency gains and overall cost reductions.

  1. Glass Coatings for Medical Training

Chemical coatings are often added to glass products to protect them from damage. Polyurethane makes another appearance here in the form of dispersions, which are used on the glass because of their scratch-resistant and shatter-resistant properties. This is particularly useful in laboratories where glass containers are often used for storage.

ReAgent supplies glass ampoules and vials to medical training programmes across the UK. For medical applications, it is important that the whole dose contained inside the ampoule can be administered without any of the product being left behind.

Silicone-based chemical coatings are the perfect solution to this problem. This type of coating provides a non-stick lining so that all the contents inside the container can easily slide out without leaving any residue. This not only improves efficiency whilst safeguarding against product shortages, but it is also a simple way to save money.

  1. Acrylic Coatings

When a piece of architecture needs a boost in aesthetic, acrylic surface coatings are a great way to enhance colour and even texture. The application of acrylic coatings is fast, convenient and provides a professional finish on a huge range of surfaces.

ReAgent works with a specialist paving company to create a bespoke acrylic coating that not only enhances the appearance of outdoor patios but also protects them against algae, weeds and oil stains.

  1. Sol-Gel Coatings

In the moulded parts industry, moulds are used to shape a variety of dynamic seals. The current method of manufacture is very inefficient; with moulds having to be continually washed and replaced, this industry sector experiences massive efficiency losses.

But the SoftSlide Project is tackling this issue by developing a semi-permanent mould release coating known as Sol-Gel. This is an innovative formulation that will be applied to moulds in order to:

  • Reduce surface tension
  • Maximise release properties
  • Improve texture transfer to the seal
  • Prevent them from bonding to moulded seal surfaces
  • Improve the overall longevity and durability of the moulds
  • Increase the number of cycles a mould can go through before cleaning or replacement

The SoftSlide Project is a European consortium dedicated to bringing about a new dynamic seal generation, and ReAgent is partners with it. Our role is to scale-up the production of Sol-Gel coatings, and we are currently in the process of gearing up to 100L batch sizes.

This revolutionary chemical coating will bring about a number of benefits to the industry:

  • Energy savings will be expected to reach €3315m per annum
  • The sales revenue of the European dynamic seal market will increase by 30%

This project shows just how effective chemical coatings can be in terms of efficiency, durability and the overall value of a product.
