THE CHALLENGE

Extraction systems for resins, epoxy resin and styrene

Resins consist in different organic materials and are viscous to different extents depending on their temperature and age. Natural resin is a viscous liquid exuded by plants. It is typically sticky, not water-soluble and mostly used for producing paints and varnishes, adhesives, flame retardants and plastics.

Especially in industry, natural resins have widely been replaced by synthetic resins today. In the construction sector, resins play an important role as binders for wood-based materials and epoxy resins or polyester resins in varnishes and plasters.

Characteristics of resins

Most synthetic resins consist of two main components when processed. Mixing these two components (resin and hardener) results in a reactive resin compound and forms an infusible plastic (thermosetting resin) after curing. Resins which harden without emitting volatile components are preferred by the industry.

In most cases, resins are produced or can be obtained as an emulsion or suspension. Generally, resins can also be used as solutions, but this use is becoming less and less popular, because the required solvents are volatile organic compounds.

Hazards from resins

Irritations to the skin and mucous membranes (e.g. in the eyes) or allergies are the main problems with resins. Severe health hazards occur after swallowing and inhaling volatile components or dusts. The curing agents or hardeners are particularly harmful, so protective measures must be taken during processing. Processing high-quality woods or treated wood entails a high risk of chronic respiratory diseases caused by resins or wood preservatives.

THE ANSWER

Using NOVUS products with resins, epoxy resin and styrene

Depending on the gases emitted, a system with activated carbon filter for adsorption can be applied, possibly combined with an upstream dust or aerosol filter. For this purpose, a multi-stage filtration is necessary, tailored to your specific requirements. Please contact us or have a look at our product pages.

THE APPLICATION

Where resins occur

The range of uses is as diverse as the number of resin types. Resins are used for coatings, adhesives and varnishes, but also for manufacturing moulded parts, foamed plastics, fibre-reinforced plastics and wood-fibre materials, as a fluxing agent when spot-welding electronics, a fuel for lamps and candles and a component of cast resin and polymer concrete.
