FAQ

• Silicone rubber is a polymeric resilient material with both inorganic and organic properties. Some examples of the applications that silicone rubber has are:
  – excellent temperature resistance
  – ozone resistance
  – oxygen resistance
  – lightfastness
  – resistance to weathering
  – excellent electrical insulation properties
  – high respiratory capacity

Silicone rubber is used for extrusion, compression moulding and calendering, among other applications.

• Silicone oils consist of linear polydimethylsiloxanes (PDMS) and are used, for example, as release agents, lubricants, heat transfer and defoaming agents.In addition, silicone oil is used as a corrosion inhibitor. An oil-impregnated surface structure effectively improves the corrosion resistance of metallic materials. Silicone oil in particular is very effective in this area.

• Silicone is a substance based on silicon. This gives silicone many advantages in terms of protection against corrosion and heat dissipation in electronics. For example, silicone has high temperature resistance, up to +260 degrees, prevents rust formation and has high resistance to moisture and chemicals. Silicone comes in various forms, such as:
  oil, grease, rubber, liquids, powders

• Solvent-based cleaners, known as ”brake clean”, are used for cleaning metal. The range includes, for example, OKS 2611, OKS 2661, OKS 2631, OKS 2671 and OKS 2681. Further information on the various cleaners:
  – 2611 can also be used on plastic
  – 2661 is intended for metal only
  – 2681 is a sealant remover and a paint and adhesive remover
  – 2671 is an NSF-approved product that may be used in the food industry. We have a wide range of foam cleaners and contact cleaners, as well as adhesive and paint removers.

• One of the differences between grease and lubricating paste is that lubricating paste contains more solid lubricants than grease does. A grease is defined as containing more than 10% of solid lubricants, whilst a grease contains less than 10%. This often determines the consistency of the grease paste – it tends to be firmer than grease generally is – but not always.
• Lubricating pastes are often ideal for plain bearings and applications with slow or vibrating movements, as well as high temperatures and loads. Grease is a lubricant whose properties depend entirely on its composition, so it is important to have a clear specification of requirements for your intended grease.

• When choosing the right grease for your machinery, there are several factors to consider:
  – What sort of applications or machinery is the grease intended for?
  – What operating temperature and speed do the machines reach?
  – What consistency of grease is ideal for your specific machinery/applications? Grease contains 80–90% base oil. The base oil can be either mineral oil or synthetic base oil; which is suitable for your operations depends on the load, operating temperatures and the speed of the machinery. Synthetic base oil can generally withstand slightly higher temperatures and loads than mineral oil.

• We offer a wide range of OKS lubricants that are food-grade and NSF-approved for both H1 and H2 types, and which are suitable for production and maintenance in, for example, the food, pharmaceutical and packaging industries.- NSF H1: Lubricants for use where incidental and unintentional contact with food or pharmaceutical products may occur.
  – NSF H2: Lubricants for use in areas where there is no risk of contact with food or pharmaceutical products. Choosing NSF-approved products does not mean compromising on performance or service life. Our OKS products combine maximum wear and corrosion protection with the utmost focus on health and the environment. This means fewer maintenance intervals, a safe working environment and minimised risk to your end product.

• Our flexible adhesives from Viscoseal provide excellent adhesion to the vast majority of materials. As this type of elastic adhesive is based on MS polymer, it can be used for bonding, sealing and jointing, and adheres effortlessly even to composite materials and plastics that are otherwise difficult to bond. With a flexibility rating of 450%, this type of adhesive can withstand both cold temperatures and impact, making it ideal for outdoor use. Furthermore, this type of adhesive is not subject to labelling requirements, meaning it has little negative impact on health and the environment, both in the short and long term.

• We prioritise health and a good working environment and therefore constantly strive to source products with as little negative impact on health and the environment as possible. We are now able to offer a wide range of non-labelling-required adhesives from Loxeal – that is, products that do not carry warning symbols or risk phrases – for a variety of applications:
  – thread locking and thread sealing
  – cylindrical mounting
  – flange seal
  – superglue
  – epoxy adhesive
  – acrylic glue

• It is important to use the right type of adhesive when bonding thick plastics, which are often considered relatively difficult to bond. “Oily plastics” include, for example, PP/PE, PP, PA, PE, ABS and PET. The reason why a specially formulated adhesive is required to bond so-called oily plastics is that these materials have a relatively low surface tension. The surface being bonded needs to have a higher surface tension than the adhesive itself. If the wrong type of adhesive is used, it is difficult to achieve good adhesion. We offer acrylic adhesives with a lower surface tension than that of the oily plastic – and which therefore provide good adhesion to both difficult-to-bond and oily plastics, as well as rubber and, for example, metal.

• To seal bolted joints, you should use an anaerobic adhesive. Anaerobic adhesives are single-component adhesives that are specially formulated to cure only when applied inside the closed thread. This ensures a highly precise and effective result. Anaerobic adhesives are highly effective for sealing bolted joints and transferring shear loads in bolted joints, for example in flange gaskets, pipe sealing, bolt locking, bonding of bushings and bearings, and in other types of cylindrical joints when bonding metal to metal.

• CA adhesive is short for cyanoacrylate adhesive, but is also known as instant adhesive or superglue. The adhesive cures through contact with moisture on the materials to be joined. The curing time is very short, and joints bonded with CA adhesive develop very high resistance to both shear and tensile forces. Our CA adhesives from Loxeal are designed for use on both porous and non-porous materials, difficult-to-bond plastics and absorbent materials, and they perform equally well on metal, plastic, rubber, paper, glass, wood and cork.
