1930s

Norman Leslie Stephen Hay pioneered hard chromium electroplating and the HoneyChrome process incorporating a microcracked, oil retaining surface

1940s

During the war years, Norman Hay worked closely with many famous names in the industry to bring engineering solutions to the war effort, with the application of hard chrome to the rockers on Rolls-Royce Merlin engines used in Spitfires, massively increasing engine service life

1950s

Development of the HAYDAN constant wattage process of hard anodising aluminium

1960s

First large scale use of vacuum distillation for industrial effluent control

First European automated production lines for electroplating plastics, ABS and Acetals

1970s

First automated production line using electroless copper to provide electromagnetic shielding for IBM computer chassis

1977

Ultraseal introduces and patents PC504 the world's first methacrylate sealant

1980s

Refinement of the HAYDAN process incorporating cobalt acetate to create thin hard anodic coatings with excellent corrosion resistance when operating in harsh marine environments

1980

Ultraseal first to introduce dry vacuum impregnation

1983

Plasticraft designed, installed and commissioned the first fully automatic chromic acid anodising plant for the UK Aerospace industry

1985

Introduction of Armourcote Tubecote X12 to the market - a unique application that acted as a facilitator in lowering the co-efficient on particularly large pre-assembled components

1988

Ultraseal first to introduce front load processing for vacuum impregnation

1993

A new coating is launched - Armourcote Lubricrome is formulated to utilise the macro-cracking that naturally exists in deposited hard chromium, harnessing the crack as a reservoir for lubrication

Ultraseal's R&D laboratories created an impregnation sealant capable of being recycled from the hot cure phase of the process, resulting in the elimination of the cold water wash phase - delivering significant environmental benefits. This advanced technology is promoted under the Autoseal Brand, available through MX Systems.

1995

Armourcote develop an electro-deposited anti-corrosion coating that enhances corrosion resistance by 300%

1998

Phosphate replacement coating launched, allowing in-situ repairs without the need for volumes of wet chemistry and consequential effluent

1999

Plasticraft introduced groundbreaking technology for their plant installed at the Canadian Helicopter Corporation. This plant, for the composite bonding of aircraft components, used modem linked technology to enable remote changes to the plc controlled functions and for 24 hour support and troubleshooting from our offices in the UK.

2000

Ultraseal International developed and launched Rexeal 100 recyclable sealant which offers increased temperature resistance, stability and overall performance

2001

Unique formulation of Armourcote 3400 enables premium threads of large subsea components to be coated creating gas tight sealing without the use of artificial or interference organic seals

2002

Ultraseal developed DB100/DB105 range of detergent and corrosion inhibitors for use in the water phases of the impregnation process to suit the more complex bi-metal components produced by today's leading edge manufacturers

2003

Ultraseal introduces Rexeal 100 - the World's Most Advanced Recycling Impregnation Sealant

2005

EC505 sealant was developed to offer excellent washing ability in the cold wash phase when used in conjunction with more basic process equipment. The sealant is a non recycling product and conforms to the NON Dead Fish/Dead Tree classification

2007

Surface Technology release the next generation of black metal finishing technology - Tricem 3800® - a new black thin film coating that provides superior corrosion and wear resistance, dramatically exceeding the performance of zinc, zinc alloy and electroless nickel plated finishes in thin film coating applications

2008

Expansioncote is developed to assist oil & gas operators and tool manufacturers globally

2009

Armourcote 3600 is applied to HMS Ambush, an astute class nuclear submarine

Surface Technology announces a managed services partnership in China with a leading automotive parts manufacturer

2011

Ultraseal first to market with 'Full Closed Loop Impregnation System'

2012

In-situ repair and maintenance capability expands after Norman Hay acquires international selective plating specialist SIFCO ASC

Acquisition of Aberdeen-based ACI Limited expands thermal spray capabilities

2014

Investment in a new Renfrew site provides specialist coating application services for large oil & gas infrastructure components up to 60ft in length
