Understanding Cut Resistant Glove Coatings

Choosing the right glove for the task at hand is essential and understanding the properties of different glove coatings is a large part of this. To keep our safety gloves at the forefront of innovation, we have incorporated new and proven technologies into the coatings of all our updated glove styles – giving our wearers the best possible protection.

TRAFFIGLOVE TECHNOLOGIES

X-DURA

This is an advanced coating technology that provides outstanding durability and ensures gloves last even longer. X-Dura features in our polyurethane (PU), nitrile and latex coatings.

MICRODEX

A ground-breaking patented coating technology with a durable nitrile blend polymer coating; extremely flexible with fantastic grip and dexterity in dry, wet and oily conditions.

Microdex Precise offers supreme grip and durability with its unique moulded cleat configuration, whilst Microdex Ultra offers maximum tactility/touch sensitivity.

LIQUIDEX

LiquiDex coating technology provides a lightweight, flexible barrier against various liquids including water, oils and many chemicals. Gloves that benefit from this technology have a high degree of comfort and superb grip in dry, wet and oily environments.

COHESION

A multi-compound technology with outstanding grip and dexterity, making it ideal for use in the glass manufacturing, metal work and automotive industry.

Cohesion Carbon (black coating) provides high abrasion oil and water resistance, whilst the high tenacity polymer increases abrasion resistance. Cohesion Crystal (transparent coating), in contrast, offers resistance to 170 degree hot melt and sealants, plus the low tack build up on the coating allows repeated application without tack transfer.

 

GLOVE COATINGS

There are 3 main coating materials used for cut resistant gloves: polyurethane, nitrile and latex.  We explore the strengths and weaknesses of each.

PU

Polyurethane is perhaps seen as the ideal choice of coating for cut-resistant gloves. This is due to its typically soft and stretchy properties, as well as having good puncture and abrasion resistance without being bulky or reducing touch sensitivity and grip.

PU is a very resilient, durable and flexible polymer. These characteristics make it an excellent general purpose, multi-industry coating that works particularly well for light manufacturing and small part assembly type operations.

The only downside to PU coatings is that they tend to have higher penetration levels into the seamless knit liner and can thereby sometimes heighten skin sensitivity issues. The PU coating is also non-breathable and so is often only used as a finger or palm dip style to reduce any perspiration build up inside the glove. 

NITRILE

Nitrile coated gloves offer excellent puncture and tear resistance and, whilst not flame-resistant *, it performs well in a range of temperatures between -4°C and 149°C.  The superior strength of nitrile rubber makes it more resistant to chemicals, oils and acid than natural rubber.

Foamed nitrile gives the coating a sponge-like property, great for when in contact with smooth, oily surfaces.  In effect, any surface oil is soaked up and displaced, meaning grip can be significantly improved.

Flat nitrile coatings provide a high level of oil and water resistance. Additionally, they offer good grip in dry conditions and solid durability with minimal micron thickness. Flat nitrile is also often combined as a knuckle or wrist dip first coat under a foam palm coating to provide a highly durable oil and water penetration resistant coating.

Overall, nitrile is a great coating to provide protection against abrasion, punctures, cuts and snags, along with chemicals, oils, greases, and fats. This makes it an excellent choice for use in abrasive material handling, building construction, small parts assembly, metal fabricating, oil and petrochemical refining, and automotive and battery manufacturing.

However, those wearing the flat or standard foam nitrile gloves may find them less dexterous as nitrile does not have the same micron thickness properties as PU, for example.

If nitrile ticks the boxes for your coating needs but you need increased tactility and comfort, then we would recommend seeking our latest Microdex technology coatings.

*EN 407 test requirements will apply.

LATEX

Latex has very high elasticity and outstanding grip compared to other glove materials, especially when it has been processed to form a crinkled surface. Crinkle surface styles offer great grip, cut/tear resilience, and are often used in handling rough wood, boxes, cut stone, scrap metal, and concrete block. Latex also has good durability and strength, and is able to withstand extreme temperature.

However, the soluble protein content levels found in some latex coated gloves can cause allergic reactions for wearers who suffer from latex allergies.
