H3453 Galvanic Corrosion Protection Tape – an answer to corrosion problems?

Friday, November 28th, 2014

Put two different metals, say aluminium and steel, in contact in a wet environment and the result is predictable – corrosion.  Specifically, a phenomenon known as galvanic corrosion will occur when metals with different electrode potentials are in contact in an electrolyte (imagine the aluminium sheet floor fixed to the steel frame of a trailer on a wet road in winter).  If measures are not taken to electrically isolate the two metals, galvanic corrosion will occur, resulting in damage and possibly danger.

There are a number of techniques available to prevent such corrosion and one of the most obvious is to separate the two metals with a non-conductive material.  At Heskins we know that in the past our customers have used our plastic materials to achieve this – and we thought we would put this to the test.

Samples of steel, stainless steel and aluminium were used in pairs in contact in a marine solution.  For each pairing, one pair had the metals in direct contact and the same pair was used with H3453 galvanic corrosion protection tape between the metals forming an isolating barrier.

The samples were then left for seven weeks.   When examined, as expected, where steel was paired with steel there was little or no corrosion and the presence or absence of the H3453 made no difference (see fig.1 & 2)

Things were different when the metals in contact were steel and aluminium.  Without a barrier there was significant corrosion, see fig. 3.

However, using H3453 galvanic corrosion protection tape to form an isolating barrier made a dramatic difference, see fig. 4.

Results were similar when aluminium was paired with stainless steel.

Summary

As can be seen, our H3452 galvanic corrosion tape makes a massive difference, it is a cost effective material that performs very effectively and provides long lasting protection to help prevent corrosion between different metals.  We can supply in roll format or die cut pieces that act as pads and virtually any shape or width can be produced.

High Quality Glow in the Dark Anti Slip Tape Now Available!

Wednesday, November 26th, 2014

high quality glow in the dark anti slip tape
Our newest addition to our range is H3452 high quality glow in the dark tape.  I will admit that the SKU is not exciting, but the product is and I would not lie to you!

Photoluminescent materials are becoming more and more prevalent, over the past few years there has been a gradual progression to regulatory approved levels of mcd/m².  The area of great interest to us is OSH1910 which relies on technical information from ASTM 2072.  ASTM 2072 stipulates that the levels of luminance at 10 minutes should be 30mcd/m² and at 60 minutes should be 4.4mcd/m², these figures are high.  DIN 67510 is a further testing standard, with PSPA providing classifications from A through D.  We wanted to take the regulatory requirement and make it applicable for a non-slip material, we further wanted to make the tape non-abrasive so it would be easy to clean (almost all will be used internally so it should be easier to clean) and we wanted the level of Coefficient of Friction (this is how grip is measured) to exceed all DIN, UKSRG etc requirements.  What a challenge as no other company has managed this.

The result is H3452.  H3452 high quality glow in the dark anti slip tape possesses levels of luminance far in excess of the regulatory requirements; H3452 possesses values of 107 mcd/m² and 32 mcd/m² at 60 minutes.  The photoluminescent test was performed by an independent external testing house and is not performed in-house (be very sceptical about tests performed, ask for external test data, generally companies overstate their own internal results)!  Our luminance results exceed the following requirements;

ASTM 2072

OSHA 1910

DIN 67510, class A

DIN 67510, class B

For Coefficient of Friction data, for Pendulum test data the product achieved an incredible 102 using TRL (dry) and 47 TRL in wet, this is far in excess of what is required for a non abrasive tape.

H3452 has so many uses, it ticks so many boxes, the photoluminescence values are incredible and the levels are exceptional.

We are now taking orders for this spectactular product, available in rolls of various widths, and die cuts. If you have a custom specification, please discuss with us, as dependent on order quantity, we are confident we can provide a solution for you.

Slip Prevention in the Winter Months

Monday, November 3rd, 2014

Heskins bolt down anti slip plates being used in snow

We are now in November, and in North America and Europe we will soon have the arrival of snow and ice. I thought I would, for once, be organized and start talking about what we can do for these conditions.

Both snow and ice create huge problems for safety.  All slip prevention materials rely on gripping the shoe (I think we should stick to shoe traffic in these situations), any substance that is detrimental to that greatly increases the risk of slippage and thus potential injury.

Snow does not initially create slip problems, fresh, soft snow with good footwear has few issues, it is the compacting and freezing of snow that creates problems.  With pressure the snow becomes more and more compact, the snow loses its ‘fluffiness’ and rapidly fills the valleys between the gripping peaks, thus decreasing, potentially removing, the grip potential of the surface.  As pressure builds up (more and more footfall pressing onto the already compacted snow) the now dense snow becomes smooth and creates a surface with lethally low levels of Coefficient of Friction (CoF).

Ice can rapidly fill valleys with almost instant high risk slip potential.

When dealing with areas at risk of snow or ice you need to ignore all materials that are not a deep abrasive product, they will not suffice, they will soon become clogged and will not give the desired level of CoF (grip).

For recommend either our coarse, or especially, our X-Coarse anti slip material, the deep valleys have far more resistance to be clogged compared to all other products available, the deeper the grit level the less chance of slippage that will be experienced with snow or ice.

Unfortunately most people like to solve a slip problem when a problem arises, i.e. when it is snowing, when it is icy etc, these are difficult application conditions due to temperature and moisture, there is an easy solution however: bolt down anti slip plates!  The plates come in two standard sizes, including an L shape for nosings, they can be coated with coarse or x-coarse and can be instantly applied, due to their mechanical fixing you can even apply in a blizzard (not endorsed by Heskins!), on request we supply relevant wood screws free of charge.  The countersunk holes ensure that the product looks superb, and more importantly helps to prevent slippage.

So ensure you’re safe and set for winter before it arrives, and contact us for a solution.
