Cold liquid applied resins

You may not have heard of them but cold liquid applied resins or liquid plastics have proven themselves as reliable solutions in the construction industry for more than 50 years. Liquid applied resins consist of one or more components, which are applied on site as a liquid, and harden as a result of a chemical cross-linking reaction or a physical drying process.

Our range of versatile, high-quality cold liquid applied waterproofing systems for roofs, and waterproofing and surfacing systems for walkways, balconies, terraces and car parks are user-friendly and provide lasting protection in a simple to apply process. Although Triflex has been manufacturing cold liquid applied waterproofing, surfacing and protection systems for over 40 years, liquid plastics can still be considered new technology when compared to traditional and sheet-applied materials.

These traditional and sheet materials are often applied using gas torches, gas burners and hot air guns, with temperatures exceeding 1,000°C in some instances. Not only do these techniques involve significant health and safety risks to operatives and persons in the vicinity, they pose a real risk of fire to the structure. The use of hot works can result in materials smouldering and subsequently igniting even after the flame has been extinguished. Many insurers will not provide cover for damage as a result of hot work and even where hot works are allowed it can be difficult to enforce a fire watch for the recommended period cessation of hot works.

Issues with hot works are largely the reason for the exponential increase in waterproofing and surfacing contractors insurance premiums in recent years with many contractors have deciding that the future lies in cold liquid applied resins based on proven technology. The number of clients banning all hot works on their properties for Health and Safety reasons also continues to increase due to the consequences of fire and availability of cold applied alternatives.

Health and Safety

The first principle of Health and Safety is to remove or eliminate the hazard where possible through redesign or substitution of a substance.

Even when hot works are redesigned with ‘safe zones’ etc. a risk of fire still exists, but this can be eliminated by substitution of the product requiring hot works with a Triflex cold liquid applied system.

The technology

Highly advanced resin technology combined with tried-and-tested systems is the formula for our success. Triflex cold liquid applied waterproofing systems are just as effective on car parks, walkways, balconies and terraces as they are on simple to complex roofs. Triflex cold liquid applied waterproofing systems are based upon the most advanced polymer chemistry and are designed to deliver long-term security.

The most frequently used polymer liquid resins in the construction industry are based on polyurethane (PU), epoxy (EP), polyurea (PUA) and polymethyl methacrylate (PMMA). Triflex manufactures resins using all of these technologies, however, the majority of Triflex resins are based on advanced PMMA technology with the other resin technologies used for more specialist applications or to fulfil specific requirements.

One of the primary benefits of Triflex PMMA resins is their exceptional reactivity even at very low temperatures:

  • The rapid cure times allow areas to be treated quickly, minimising time on site
  • Access restrictions can be minimised as the materials achieve full mechanical properties exceptionally quickly, and all layers of Triflex systems can be trafficked shortly after installation
  • With extremely short ‘rain proof' times, weather windows can also be maximised
  • The installer can leave the site, confident that the areas completed are secure
  • With the ability to cure at low temperatures, Triflex projects can be carried out all-year-round and in the majority of climatic conditions, allowing the project to be completed when required

Triflex PMMA resins offer further benefits over other resin types, with better hydrolysis and alkali hydrolysis resistance (resistance to standing water and ponding water and alkaline cement water), higher levels of inter layer adhesion, and applicability at humidity levels of up to 95%. Triflex PMMA resins are also UV resistant and able to withstand severe chemical and mechanical loads. Clients and installers save both time and money with Triflex and at the same time obtain a solution of outstanding quality, offering long-term durability, integrity and security.
